+This is the 57th release of NuttX. This release includes a combination
+of some new features as well as several bugfixes. New features
include:
- * TI/Luminary Stellaris LM3S9B96:
- Header file changes contributed by Tiago Maluta.
- * TI/Luminary Stellaris LM3S8962:
- Header file changes and support for the Stellaris LM3S8962
- Ethernet+CAN Evaluation Board contributed by Larry Arnold.
- * On-Demand Paging Support:
- The basic logic for the On-Demand Paging feature is complete,
- implemented for the NXP LPC3131, and partially tested. See
- https://nuttx.apache.org/docs/latest/components/paging.html.
- Some additional test infrastructure will be needed in order to complete
- the verification. See configs/ea3131/README.txt for details.
- * Two Pass Build Support:
- The make system now supports a two pass build where a relocatable,
- partially linked object is created on the first pass and that
- object is linked with the NuttX libraries to produce the final
- executable on the second pass. This two pass build is currently
- only used to support the On-Demand paging feature: The first
- pass link forces critical logic into the locked text region;
- the second pass builds the NuttX executable more-or-less as
- normal.
- * CONFIG_APP_DIR:
- Generalized the way in which applications are built and linked
- with NuttX. The new configuration CONFIG_APP_DIR replaces
- CONFIG_EXAMPLE. CONFIG_EXAMPLE used to identify the sub-directory
- within the NuttX examples/ directory that held the example
- application to be built. That made it awkward to configure to
- build an application that resides outside of the NuttX examples/
- directory. CONFIG_APP_DIR is more general; it can be used to
- refer to any directory containing the application to be built.
-
- For people who have their own configurations and/or Makefiles,
- you will need to make a couple of changes:
-
- - Replace all occurrences of CONFIG_EXAMPLE=foobar with
- CONFIG_APP_DIR=examples/foobar in all of the configuration
- files.
- - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with
- $(CONFIG_APP_DIR)
- - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT)
- with libapp$(LIBEXT) in your Makefiles.
- - Check any other occurrences of CONFIG_EXAMPLE.

- some warnings. See the ChangeLog for details.

Important bugfixes include:
- * Cortex-M3 Hard Fault. Fixed a hard fault problem that can occur
- if certain types of interrupts are pending at the time another
- interrupt returns. This problem has only been observed on the
- LPC1766 (returning from a SYSTICK interrupt with a pending
- Ethernet interrupt). However, it is assumed that all Cortex-M3
- ports could have this as a latent bug.
-
- * TCP/IP Sequence Number Bug. Corrected errors some important
- logic in the way that sequence numbers are managed when send()
- sends out packets before a previous packet has been acknowledged.
- Some of that send() logic was incompatible with logic in the
- uIP layer. Errors seen include: (1) The final final packet in
- a sequence of packets might be too large! In the THTTPD example,
- this might leave some garbage at the bottom of the display. Or
- (2) send() might hang with outstanding, unacknowledged data
- (and with no re-transmission requests). This was due to
- differences in sequence number handling in send() and in
- uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) that all
- of the bytes were acknowledged; send.c knew that they were not.
-
- * One-Shot POSIX Timer Bug. Fixed an error in set-up of a one-shot
- POSIX timer. It was using the repetitive timer value (which
- is zero in the one-shot case), always resulting in a 10Ms timer!
- Found and fixed by Wilton Tong.

-Additional support has been included for the Olimex-LPC1766. Support
-for that board was added to NuttX 5.13. This release extends that

+2010. This release includes several bugfixes as well as feature
enhancements, primarily for the Olimex LPC1766-STK board.
Important bugfixes included:
- * Additional fixes needed with the TCP sequence number problem
- "fixed" in NuttX-5.14.
- * In the send() logic, now checks if the destination IP address
- is in the ARP table before sending the packet; an ARP request
- will go out instead. This improves behavior, for example, on
- the first on the first GET request from a browser
- * All USB class drivers need to call DEV_CONNECT() when they are
- ready to be enumerated. That is, (1) initially when bound to
- the USB driver, and (2) after a USB reset.
- * The SPI_SETBITS macro was calling the SPI setmode method.
- * And several other bug fixes of lower importance (see the
- ChangeLog for details).

Below is a summary of the NuttX USB host implementation as extracted
from the NuttX Porting Guide:
- 6.3.9 USB Host-Side Drivers
- * include/nuttx/usb/usbhost.h. All structures and APIs needed to
- work with USB host-side drivers are provided in this header
- file.
- * struct usbhost_driver_s. Each USB host controller driver must
- implement an instance of struct usbhost_driver_s. This structure
- is defined in include/nuttx/usb/usbhost.h. Examples:
- arch/arm/src/lpc17xx/lpc17_usbhost.c.
- * struct usbhost_class_s. Each USB host class driver must implement
- an instance of struct usbhost_class_s. This structure is also
- defined in include/nuttx/usb/usbhost.h. Examples:
- drivers/usbhost/usbhost_storage.c
- * USB Host Class Driver Registry. The NuttX USB host infrastructure
- includes a registry. During its initialization, each USB host
- class driver must call the interface, usbhost_registerclass()
- in order add its interface to the registry. Later, when a USB
- device is connected, the USB host controller will look up the
- USB host class driver that is needed to support the connected
- device in this registry. Examples: drivers/usbhost/usbhost_registry.c,
- drivers/usbhost/usbhost_registerclass.c, and
- drivers/usbhost/usbhost_findclass.c,
- * Detection and Enumeration of Connected Devices. Each USB host
- device controller supports two methods that are used to detect
- and enumeration newly connected devices (and also detect
- disconnected devices):
- + int (*wait)(FAR struct usbhost_driver_s *drvr, bool connected);
- Wait for a device to be connected or disconnected.
- + int (*enumerate)(FAR struct usbhost_driver_s *drvr);
- Enumerate the connected device. As part of this enumeration
- process, the driver will (1) get the device's configuration
- descriptor, (2) extract the class ID info from the configuration
- descriptor, (3) call usbhost_findclass() to find the class
- that supports this device, (4) call the create() method on
- the struct usbhost_registry_s interface to get a class instance,
- and finally (5) call the connect() method of the struct
- usbhost_class_s interface. After that, the class is in charge
- of the sequence of operations.
- * Binding USB Host-Side Drivers. USB host-side controller drivers
- are not normally directly accessed by user code, but are usually
- bound to another, higher level USB host class driver. The class
- driver exports the standard NuttX device interface so that the
- connected USB device can be accessed just as with other, similar,
- on-board devices. For example, the USB host mass storage class
- driver (drivers/usbhost/usbhost_storage.c) will register a
- standard, NuttX block driver interface (like /dev/sda) that can
- be used to mount a file system just as with any other other
- block driver instance. In general, the binding sequence is:
-
- 1. Each USB host class driver includes an initialization entry
- point that is called from the application at initialization
- time. This driver calls usbhost_registerclass() during this
- initialization in order to makes itself available in the
- event that the device that it supports is connected. Examples:
- The function usbhost_storageinit() in the file
- drivers/usbhost/usbhost_storage.c
- 2. Each application must include a waiter thread thread that
- (1) calls the USB host controller driver's wait() to detect
- the connection of a device, and then (2) call the USB host
- controller driver's enumerate method to bind the registered
- USB host class driver to the USB host controller driver.
- Examples: The function nsh_waiter() in the file
- configs/nucleus2g/src/up_nsh.c and the function nsh_waiter()
- in the file configs/olimex-lpc1766stk/src/up_nsh.c.
- 3. As part of its operation during the binding operation, the
- USB host class driver will register an instances of a standard
- NuttX driver under the /dev directory. To repeat the above
- example, the USB host mass storage class driver
- (drivers/usbhost/usbhost_storage.c) will register a standard,
- NuttX block driver interface (like /dev/sda) that can be
- used to mount a file system just as with any other other
- block driver instance. Examples: See the call to
- register_blockdriver() in the function usbhost_initvolume()
- in the file drivers/usbhost/usbhost_storage.c.

+standard, NuttX block driver interface (like /dev/sda) that can
+be used to mount a file system just as with any other other
+block driver instance. In general, the binding sequence is:
+
+1. Each USB host class driver includes an initialization entry
+point that is called from the application at initialization
+time. This driver calls usbhost_registerclass() during this
+initialization in order to makes itself available in the
+event that the device that it supports is connected. Examples:
+The function usbhost_storageinit() in the file
+drivers/usbhost/usbhost_storage.c
+2. Each application must include a waiter thread thread that
+(1) calls the USB host controller driver's wait() to detect
+the connection of a device, and then (2) call the USB host
+controller driver's enumerate method to bind the registered
+USB host class driver to the USB host controller driver.
+Examples: The function nsh_waiter() in the file
+configs/nucleus2g/src/up_nsh.c and the function nsh_waiter()
+in the file configs/olimex-lpc1766stk/src/up_nsh.c.
+3. As part of its operation during the binding operation, the
+USB host class driver will register an instances of a standard
+NuttX driver under the /dev directory. To repeat the above
+example, the USB host mass storage class driver
+(drivers/usbhost/usbhost_storage.c) will register a standard,
+NuttX block driver interface (like /dev/sda) that can be
+used to mount a file system just as with any other other
+block driver instance. Examples: See the call to
+register_blockdriver() in the function usbhost_initvolume()
+in the file drivers/usbhost/usbhost_storage.c.

- * Added support for the STM3210E-EVAL board: (1) LCD in either
- landscape or portrait mode, and (2) interrupting buttons.
- * Added a configuration option to use different serial ports for
- debug and for the NSH serial console (there are some issues
- with CR-LF expansion and character echo if NSH is not run on
- the console).
- * Standardized the button press and button interrupt interfaces
- so that they are common across all boards.
- * Added a new graphics example that focuses on placing text on
- the background while pop-up windows occur. Text should continue
- to update normally with or without the popup windows present.
- * Added ARM stack checking logic.

Additional new features and extended functionality:
- * RTOS:
-
- - Implemented the POSIX pause() function (still has some compiance
- issues).
- - Tasking logic is extended to support the notion of address
- environments. An address environment is the key notion underlying
- "process" vs. tasks. If tasks are created with address environments
- (by binfmt), the OS will propagate that environment to child threads
- and will destroy the address environment when the "process" exists.
- - If support for the PATH variable is enabled, the OS start up logic
- will create an initial environment containing the default PATH
- setting (CONFIG_PATH_INITIAL). This initial PATH will then be
- inherited by all tasks.
-
- * Binfmt
-
- - The NuttX binary loaders have been updated to support the PATH
- environment variable. Now, if the PATH is properly defined, programs
- can be executed from mass storage using only the file name. This
- feature is added to support more standard behavior (eventually, NSH
- will support execution of programs in file systems by just entering
- the file name, perhaps in 6.25?).
- - The NXFLAT and ELF binary loaders have been extended to create
- address environments for any new tasks executed from the file system.
- This feature requires that the architecture support a memory management
- unit (MMU) and the address environment interfaces declared in
- include/nuttx/arch.h (currently, this is only supported by the z180).
-
- * Drivers: LCD driver for the Univision UG-2864AMBAG01 OLED
-
- * STM32: Support for STM32F100 high density chips contributed by Freddie
- Chopin.
-
- * STM32 Drivers: Added optional RS-485 direction bit control (from
- Freddie Chopin).
-
- * STM32 Boards:
-
- - Support for generic STM32F100RC board contributed by Freddie Chopin.
- - stm32f4discovery/nxlines: STM32F4Discovery support for the
- UG-2864AMBAG01 OLED.
- - stm32f4discovery/winbuild: A version of the NuttX OS test
- configured to build natively on Windows.
- - stm32f4discovery/elf: Now uses the PATH variable to find ELF
- executables.
- - configs/cloudctrl: Added for Darcy Gong's CloudController board
-
- * PIC32 Boards: Update the Mirtool configuration for Release 2 of the
- Mirtoo module.
-
- * Calypso: Add Calypso keypad driver. From Denis Cariki.
-
- * ZiLOG:
-
- - Add support for the z180 chip family and, specifically, for
- the P112 retro hardware (see http://p112.feedle.net/).
- - All ZiLOG configurations updated to use the current ZDS-II
- and/or SDCC toolchains.

-
- * C++: Exception stubs from Petteri Aimonen.
-
- * Applications:
-
- - Add NSH hexdump command to dump the contents of a file (or character
- device) to the console (contributed by Petteri Aimonen).
- - Extend the NSH ifconfig command plus various DHCPC improvements
- (from Darcy Gong).
-
- * apps/examples:
-
- - ostest: Replace large tables with algorithmic prime number
- generation. This allows the roundrobin test to run on platforms
- with minimal SRAM (Freddie Chopin).
- - keypadtest: A new keypad test example contributed by Denis Carikli.
- - elf and nxflat: If CONFIG_BINFMT_EXEPATH is defined, these examples
- will now use a relative path to the program and expect the binfmt/
- logic to find the absolute path to the program using the PATH
- variable.
-
- * Build system:
-
- - New top-level Makefiles: Makefile.unix and Makefile.win (along with
- numerous changes to other make-related files). This adds basic
- support for building NuttX natively under Windows from a CMD.exe
- window (rather than in a POSIX-like environment). This build: (1)
- Uses all Windows style paths, (2) Uses primarily Windows batch
- commands from cmd.exe, with (3) a few extensions from GNUWin32.
-
- This capability should still be considered a work in progress
- because: (1) it has not been verfied on all targets and tools,
- and (2) still lacks some of the creature-comforts of the more
- mature environments (like a function configure.sh script and
- 'make menuconfig' support).
-
- - Example Windows native builds for STM32F4Discovery, eZ80, z16f, z8,
- Z80, and Z180.
- - Several configurations have been converted to work the kconfig-
- frontends mconf configuration tool: stm32f4discovery/nxlines, and
- all eZ80, z16f, z8, Z80, and Z180 configurations.
- - Architectures now include a common Toolchain.defs file that can be
- used to manage toolchains in a more configurable way (most of this
- contributed by Mike Smith).
-
- * Build tools:
-
- - Renamed tools/winlink.sh to tools/copydir.sh.
- - Several new tools/scripts to support the Windows native build:
- tools/mkdeps.bat, tools/mkdeps.c, tools/link.bat, unlink.bat, and
- copydir.bat.
- - tools/incdir.sh and incdir.bat now support an -s option to generate
- system header file paths.
- - tools/b16.c: Fixed precision math conversion utility.

Additional new features and extended functionality:
- * OS Initialization
-
- - Removed support for CONFIG_BUILTIN_APP_START. This is not really a
- useful feature and creates a violation of the OS layered
- architecture.
-
- * Task Creation:
-
- - Implement a simple vfork(). In NuttX-6.25, this interface is
- available only for ARM7/9, ARMv7-M (Cortext-M3/4), and MIPS32
- (PIC32MX) platforms.
- - exec() now sets the priority of the new task to the same priority as
- the parent task (instead of the arbitrary value of 50).
- - New, partially compliant implementations of execv() and execl().
- These are only partially compliant because they do not overlay any
- existing "process space" but rather create the new task and exit().
- - Add a complete implementation of posix_spawn(). This standard
- interface is a better match for an MMU-less architecture than are
- vfork() plus execv() or execl().
- - Add a task start hook that will be called before the task main
- is started. This can be used, for example, to schedule C++
- static constructors to run automatically in the context of the
- new task.
-
- * Task Parentage
-
- - Repartitioned tasking data structures. All shared resources are now
- collected together in a "task group". A task group includes the
- original task plus all of the pthreads created by the task.
- - Added support for remember the parent "task group" when a new task is
- started.
- - Added optional support to record the membership of each thread in
- the "task group".
- - Implement support for retaining child task status in the "task group"
- after the child task exists. This is behavior required by POSIX.
- But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and
- CONFIG_SCHED_CHILD_STATUS
- - Add internal logic to "reparent" a task. This is useful,
- for example, where the child task is created through a trampoline
- task that redirects I/O. Reparenting allows the caller of posix_spawn()
- to be reparented for the eventual child thread.
- - Added support for SIGCHLD. Sent to all members of the parent task
- group when the file member of the child task group exits.
- - If SIGCHLD and retention of child task exist status are enabled, then
- a more spec-compliant version of waitpid() is enabled.
- - New interfaces waitid() and wait() are also enabled when SIGCHLD
- is enabled.
-
- * File System
-
- - dup() and dup2() can new be used with opened files in a mounted file
- system. This supports re-direction of output in NSH to files.
- - The binfs file system was moved from apps/builtin to fs/binfs. The
- binfs file system was extended to support execution of "builtin
- applications" using exec(), execv(), execl(), or posix_spawn().
- - Added logic based on SIGCHLD to automatically unload and clean-up
- after running a task that was loaded into memory.
-
- * Binary Formats
-
- - Much of the logic for "builtin applications" was moved from
- apps/builtin to nuttx/binfmt/libbuiltin. Includes some extensions
- contributed by Mike Smith.
- - A binary loader was added for builtin applications to support
- execution of "builtin applications" using exec(), execv(),
- execl(), or posix_spawn().
-
- * Drivers:
-
- - Added logic to marshal and serialized "out-of-band" keyboard
- commands (such as cursor controls and key release events) intermixed
- with normal ASCII keypress data. The encoding is partially integrated
- in the HID keyboard driver and the decoding full integrated into the
- apps/examples hidkbd and keypadtest (the latter contributed by Denis
- Carlikli).
- - Driver for the UG-2864HSWEG01 OLED contributed by Darcy Gong.
- - Add support for removable serial devices (like USB serial). This
- support is enabled by CONFIG_SERIAL_REMOVABLE.
-
- * ARMv7-M:
-
- - Added an option to use the BASEPRI register to disable interrupts
- (instead of the PRIMASK). This eliminates some innocuous hardfaults
- that interfere with some debug tools. You need to switch to the
- BASEPRI method only if you have such tool interference.
-
- * STM32 Drivers
-
- - Bring STM32 F1 DMA capabilities up to par with the STM32 F2/F4
- (contributed by Mike Smith).
- - Add support for USART single wire mode (Contributed by the PX4
- team).
- - Updates to support for SPI DMA on the STM32 F1/F2/F4. From
- Petteri Aimonen.
-
- * STM32 Boards:
-
- - New configuration to support the UG-2864HSWEG01 OLED on the
- STM32F4Discovery board.
- - Added a posix_spawn() test configuration for the STM32F4Discovery.
-
- * LM3S/LM4F
-
- - Files and directories repartitioned to support both LM3S and LM4F
- using the STM32 organization as a model.
- - Partial definitions for the LM4F contributed by Jose Pablo Carballo
- (this is still a work in progress).
-
- * LM3S Boards
-
- - Added scripts and documentation to use OpenOCD with the LM3S (from
- Jose Pablo Carballo).
-
- * LPC176x/LPC178x
-
- - Files and directories repartitioned to support both LPC175x/LPC176x
- and the LPC177x/LPC178x families using the STM32 organization as a
- model. The LPC1788 port is a work in progress by Rommel Marcelo.
-
- * LPC176x/LPC178x Boards:
-
- - Added a configuration to support the Wave Share Open1788 board.
- This is still a work in progress by Rommel Marcelo.
-
- * LPC2148 Boards:
-
- - Add basic support for the The0.net ZP213x/4xPA board (with the LPC2148
- and the UG_2864AMBAG01 OLED).
- - Add an nxlines configuration for the ZP213x/4xPA (with the LPC2148
- and the UG_2864AMBAG01).
-
- * Simulator:
-
- - Add an nxlines configuration for the simulator.

- TCB structure into the task group: pthread join data,
- atexit/on_exit callbacks, waitpid data structures, and message
- queues.
- - TCBs for tasks and pthreads are now separate structures. This
- saves a little memory since tasks do not have to carry the overhead
- for threads and vice versa.

- * Kernel Build:
+* Kernel Build:
- - Extensive changes were made to support the kernel build mode. In
- this mode, NuttX is built as a monolithic kernel. NuttX is built
- as a separate kernel mode "blob" and the applications are built
- as a separate user mode "blob". The kernel runs in kernel mode and
- the applications run in user mode (with the MPU restricting user
- mode accesses). Access to the kernel from the user blob is only
- via system calls (SVCalls).
- - Extensive changes were made to the syscall, SVCall, and trapping
- logic. Many internal interfaces were renamed.
- - The memory manager was extended to support both kernel- and user-
- mode allocations. Logic within the kernel needs to use the
- correct kernel- or user-space allocator, depending upon the user
- of the allocated memory.
- - The user-space blob now contains a header built in at the beginning
- of the block that provides the same information that was previously
- provided by a kludgy, auto-generated header file (user_map.h).
- - Basic support implemented for the ARMv7-M family with fragments
- also implemetned for the ARMv6-M and MIPS32 families.
- - Kernel build supported added for the LPC17xx Open1788 and for
- the Atmel SAM3U-EK board. All testing is being performed on the
- Open1788 board.

- the applications run in user mode (with the MPU restricting user
- mode accesses). Access to the kernel from the user blob is only
- via system calls (SVCalls).
- - Kernel build configurations for the Open1788 board and for the
- STM32F4Discovery now execute correctly.
- - Changes were made to task and thread start-up routines, signal
- handling, data structures, ARMv7-M SVCalls, stack management

- * STM32:
-
- - Added an option to conditionally disable the "wfi" sleep mode. This
- is needed with certain JTAG debuggers to prevent the debug session
- from being disconnected (from Ken Pettit).
- - Added support for the STM32L (STM32L15X/STM32L16x) family.
- - Added STM32F103C4 and F103C8 chip support (from Laurent Latil).
- - Added a new interface function, stm32_dmacapable() that can be used
- to determine if DMA is possible from the specified memory address
- (from Petteri Aimonen)
-
- * STM32 Drivers:
-
- - If CONFIG_STM32_DMACAPABLE is defined, the STM32 SPI driver now uses
- stm32_dmacapable() to determine if it is possible to perform DMA
- from the specified address. This change is important for the STM32
- F4 which may have SPI data buffers allocated on the stack in CCM
- memory which cannot support the DMA (from Petteri Aimonen).
-
- * STM32 Boards:
-
- - Support added for the MikroElektronika Mikromedia for STM32F4
- development board (from Ken Pettit) with the MIO283QT2 LCD and
- touchscreen. Several graphics configurations are included.
- - The HY-mini STM32v board now uses the common SSD1289 driver
- and supported the card detect interrupt. Several new
- configurations also added and some removed (from Laurent Latil).
- - Support added for the R65105-based LCD that comes with some
- HY-Mini STM32v boards (from Christian Faure).
- - Added basic support for the STM32L-Discovery board. Drivers
- for the on-board segment LCD are included.
- - Added support for the STM32 Tiny development board based on the
- STM32 F103C8T6 MCU. This includes support for the nRF24L01+
- wireless on the board (from Laurent Latil).
-
- * Stellaris LM3S/LM4F:
-
- - Support added for a TI/Stellaris internal FLASH MTD driver (from Max
- Holtzberg).
-
- * Stellaris LM4F Boards:
-
- - The LM3S6965-EK now has configurations for the UDP discovery tool and
- for the TCP echo server (both from Max Holtzberg)
-
- * Atmel ATSAM3/4:
-
- - Reorganized, renamed, and updated directory structure to better
- support additional members of the SAM3/4 family.
- - Added support for both the ATSAM4S and ATSAM4L families. The
- ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a
- different beast, really much more akin to the AVR32s SoCs but
- with a Cortex-M4.
-
- * Atmel ATSAM3/4 Boards:
-
- - Added support for the Atmel SAM4L Xplained Pro development board.
- This board features the ATSAM4LC4C MCU (Cortex-M4 with 256KB FLASH +
- 32KB SRAM).
- - Added support for the Atmel SAM4S Xplained development board. This
- board features the ATSAM4S16C MCU (Cortex-M4 with 1MB FLASH + 128KB
- SRAM).
-
- * PIC32MX Boards:
-
- - Added support for the 1602 segment LCD on-board the Sure PIC32MX
- board. This board will now also support a USB NuttX console and
- the USB monitor test program.
-
- * Build System:
-
- - Clean-up of almost all .gitignore files: Made scope of ignore to be
- only the current directory; Ignore .dSYM files in directories where
- .exe's may be built. Also, in Makefiles, clean .dSYM files in
- directories where an .exe may be built.
- - Standardize and consolidated all build-as-an-NSH-application
- configuration settings. Now only CONFIG_NSH_BUILTIN_APPS is
- sufficient to build an application, test, or or example as an NSH
- builtin application.
- - Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI
- toolchains.
-
- * Libraries:
-
- - Added encoder/decoder logic to marshal and serialize special segment
- LCD (SLCD) commands intermixed with normal ASCII data. This is the
- similar to the encoding/decoding logic that is used to marshal
- special commands from a keyboard.
- - Add dprintf() and vdprintf() (the latter from Andrew Tridgell).
- - Add an application that may be built as an NSH builtin command that
- will erase FLASH using a flash_eraseall NSH command (from Ken Pettit).
-
- * Applications:
-
- - Added an MTD partition test/examples. Currently used with (1) the a
- simulation configuration to test MTD partitions on a RAM emulation
- of FLASH and (2) with the Mikroe STM32F4 configuration.
- - Added a test/example to verify alphanumeric, segment LCDs.
- - Added a simple single threaded, poll based TCP echo server based
- on W. Richard Stevens UNIX Network Programming Book (from Max
- Holtzberg).
- - Added several tests of the SMART block driver and file system (from
- Ken Pettit).
- - Added a runtime configuration for the UDP discover utility (from
- Max Holtzberg).
- - Added an example application to demo the nRF24L01 driver (from
- Laurent Latil).
- - New and modified NSH commands:
- Added a -h option to the df command to show the volume information
- in human readable form (from Ken Petit).
- Add a new mksmartfs command (from Ken Petit).

+simulation configuration to test MTD partitions on a RAM emulation
+of FLASH and (2) with the Mikroe STM32F4 configuration.
+- Added a test/example to verify alphanumeric, segment LCDs.

-
- - CC3000 Networking. Initial support for the TI CC3000 network
- module on the Freescale Freedom-KL25Z board from Alan Carvalho
- de Assis. This is still a work in progress.
-
- * kconfig-fronted Configuration:
-
- - Conversion of old configurations to use the kconfig-frontends
- tool is an ongoing effort that will continue for some time.
- At this time, only 46% of the configurations have been converted
- to use the kconfig-frontends tools.
-
-Bugfixes (see the ChangeLog for details). Some of these are very important:
-
- * File Systems:
-
- - ROMFS: Fix an error where long (>15) file names were read
- incorrectly from a ROMFS file system. From Mike Smith
- - NXFFS: Clean up some compiler warnings.
-
- * Common Drivers
-
- - MMC/SD driver: Correction for a bad return value when multiple
- block SDIO transfers are suppressed. By Andrew Tridgell.
- - USB HID keyboard and mass storage host-side class drivers: Fix some
- compilation errors and warnings when pre-allocated data structures
- are used.
- - USB device-side class drivers: Fix some compilations errors when
- DUALSPEED (i.e., full- and high-sped) support is enabled.
- - CDC/ACM and PL2303: Don't use max packetsize assigned to the endpoint
- when allocating request buffers; The default value of the endpoint
- max packetsize may be incorrect because the endpoint has not yet
- been configured. Really only an issue for high-speed endpoints.
- - USB Host Mast Storage Class: Fixed a problem that was causing some
- devices to fail to initialize: If device is returning fatal transfer
- errors while attempting to initialize, don't bother with the startup
- retries; abort immediately so that the device will be reset and we
- can try again with a better ready device.
- - USB Host Mast Storage Class: Correct a reference counting error:
- When an MSC device transfer fails while waiting for UnitTestReady,
- the reference count on the class was not being decremented. The end
- result is a memory leak as can be seen by the USB device numbers
- incrementing: sda, sdb, sdc, ...
- - USB Device CDC/ACM: Fix backward conditional compilation in the
- CDC/ACM driver with regard to remote wakeup and self-powered
- capabilities. From the PX4 team via Lorenz Meier,
-
- * Networking / Network Drivers
-
- - ARP IP harvesting: Correct backward condition in netmask task.
- From Max Holtzberg.
- - Network connection monitor: Fixes a race condition where a loss of
- connection may not be detected when the connection is lost before it
- has been accepted (from Max Holtzberg).
- - TCP/IP Backlog: Fix a critical bug in the TCP/IP backlog
- initialization: Only the first backlog buffer was getting added to
- the free list. From Max Holtzberg.
- - ENC28J60: Fixes and improvements back-ported from the ENCX24J600
- to the ENC28J60 by Max Holtzberg.

- - STM32 I2C Correct an error that crept into the STM32 F1 I2C
- driver with some recent changes. From Librae
- - STM32 F4: Added some missing CONFIG_SERIAL_TERMIOS support; Fixed
- some STM32 F4 Timer 8 pin configurations. From CCTSAO.
- - STM32 SDIO: If CONFIG_SDIO_BLOCKSETUP defined, OS would crash. Now
- Generate an error if CONFIG_SDIO_BLOCKSETUP is defined; that
- option is not yet supported by the STM32 SDIO driver. From CCTSAO
- - STM32 I2C Timers: Some CCER bit settings changed. Submitted by
- CCCTSAO.
- - STM32 CAN: Fix access to CAN filter registers. From the PX4 team
- via Lorenz Meier.
- - STM32 Kconfig: Fix STM32 UART7/8 Kconfig names and UART DMA. From
- the PX4 team via Lorenz Meier.
-
- * LPC17xx Drivers
-
- - Fix #endif with missing #if in USB host header file. Reported
- by Andrew Bradford,

- reversed in a function call.
- - Correct a race condition in the HSMCI driver when an interrupt
- occurs before the wait for the interrupt begins.
- - Peripheral clock setup: Correct a typo in a register name.
-
- * Atmel AT91 SAMA5D3

- - Order of some operations changed in boot-up logic to defer
- enabling of caching of memory regions until SDRAM is initialized.
- - Correct handling of spurious interrupts.

-
- - KL25Z SPI: Correct typo in name of a function. From Alan Carvalho
- de Assis.
-
- * Applications:
-
- - apps/examples/composite: Fix a typo that can cause a configuration
- error. From CCTSAO.
- - apps/examples/pwm: Clean-up some configuration confusion.
- - apps/netutils/dhcpd/dhcpd.c: Fixed calculation of the next lease
- address. From Paolo Messina.
- - apps/examples/usbmsc: Don't try to control USB trace if we are
- an NSH built-in task. In that case our attempts are inadequate
- and only interfere with with other logic that is attempting to
- to do the same thing (in NSH or in the USB monitor).
- - apps/examples/usbmsc: IMPORTANT bug fix: Change how the msconn
- works. Because of recent changes the msconn command was hanging.
- This was because the USB MSC start-up logic creates a pthread;
- Now waitpid() will wait until all members of the task group
- exit. So NSH was hanging in waitpid when msconn started even
- though msconn returned. The USB MSC logic really should not use
- a pthread, but we are stuck with that for now. The work-around
- is the msconn now daemonizes itself so that it so that the pthread
- is created in a different task group.
- - apps/nshlib: Fix NSH listing output for the case of a single file.
- From the PX4 team; provided by Lorenz Meier.

NuttX-6.31
----------
The 98th release of NuttX, Version 6.31, was made on October 28, 2013,
-and is available for download from the SourceForge website. Note
-that release consists of two tarballs: nuttx-6.31.tar.gz and
-apps-6.31.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-6.31.tar.gz and
+apps-6.31.tar.gz. Both may be needed (see the top-level nuttx/README.txt
file for build information).
Additional new features and extended functionality:
- * General:
-
- - Standardized stack checking logic so the interfaces can be used
- by common stack monitoring logic.
-
- * Audio Subsystem and Audio Drivers:
-
- - Ken Pettit has finally released his long awaited audio subsystem.
- This is a generic audio subsystem that is appropriate for the
- deeply embedded MCU. Current testing has, however, been focused
- on the VS1053 CODEC chip.
- - Ken Pettit's VS1053 audio CODEC driver is now functional.
-
- * Networking / Network Drivers
-
- - Add the prefix ETH0 to all PHY configuration selections. This
- will allow us to support to Ethernet MAC drivers with two different

- the router, vs the MAC address of the peer.
- - Make net_close() nonblocking and free unestablished connections if
- no free connections available. From Max Holtzberg.
- - Changed the meaning of the uip_*input functions. They now return

- driver that must make a decision to return the packet or not: It
- should not retry dropped packets. From Max Holtzberg.
- - David Sidrane has completed integration of the CC3000 networking.
- This is much more than a network driver: It is a complete
- replacement for the NuttX networking with off-chip networking support
- in the CC3000.

+- Add configuration for the Spark Core. The initial check-in is
+basically the Maple Mini board and subsequent development by David
+Sidrane is his special Spark emulation hardware. The configuration
+should be very mature when actual Spark hardware is available.
+- Support for the Olimex STM32 P207 board added by Martin Lederhilger.
+- Configuration for the Mikroe STM32F4 board configuration updated for
+audio support by Ken Pettit.
+
+* NXP LPC17xx Boards:
+
+- zkit-arm-1769: LED1 is now user controllable after booting. From
+Rashid Fatah.
+
+* Kinetis KL Drivers:
+
+- PIT and TPM register definitions header files for the from Alan
+Carvalho de Assis.
+- Added low-level getc() function for operation with no file system.
+The KL25Z can now support NSH in a very minimal system that does
+not even have a file system.
+
+* Kinetis KL Boards
+
+- A new configuration called minnsh was added is an experiment to
+see how small we can get the NuttX footprint and still support NSH.
+From Alan Carvalho de Assis..
+
+* TI Calypso Phones:
+
+- Basic board support for the Motorola C139 (Compal E86) phone. From
+Craig Comstock.
+
+* Applications:
+
+- Moved several useful examples from apps/examples to apps/system.
+This includes USB MSC, USB CDC/ACM, and USB Composite.
+- New addroute and delroute commands added to NSH in order to manage
+the network routing table.
+- Numerous enhancements and updates to the CC3000 example from David
+Sidrane.
+- Add a new stack monitor daemon that can be used to constantly
+monitor stack usage by all threads.
+- Numerous changes to get NSH working with no file system. Basically
+this suppresses I/O redirection and replaces file I/O with calls to
+low-level console read/write functions. Suggested by Alan Carvalho
+de Assis.
+- apps/system/nxplayer: A new, command-line media player called
+'nxplayer' from Ken Pettit.
+- apps/examples/random: Add a simple test that dumps values from
+/dev/random.
+- apps/examples/adc: Add support so that a ADC driven by software
+triggering can be tested.
+
+* Build System:
+
+- The MKDEP tools now support a new argument that identifies the
+object file path.
+
+Efforts In Progress. The following are features that are partially
+implemented but present in this release. They are not likely to be
completed soon.
- * kconfig-fronted Configuration:
-
- - Conversion of old configurations to use the kconfig-frontends
- tool is an ongoing effort that will continue for some time.
- At this time, only 48% of the configurations have been converted
- to use the kconfig-frontends tools.
-
-Bugfixes (see the ChangeLog for details). Some of these are very important:
-
- * Initialization and Scheduling:
-
- - IDLE thread initialization logic should not call group_setupidlefiles()
- if there are no file descriptors (and, hence, no file system).
- - Fix some cornercase error handling logic: If sched_releasetcb() is
- called as part of a failed pthread startup before the flags field in
- the TCB has been initialized, then a crash occurs. Pointed out by
- David Sidrane.
-
- * Networking / Network Drivers:
-
- - Look up of a device using subnet will fail if the packet is being
- sent out of our subnet (via a router). The fallback here is just to
- use the only device ("eth0") if the subnet lookup fails (this logic
- was extended to handle multiple Ethernet devices by adding a simple
- routing table).
- - Fix some backward conditional logic in send() that enabled the
- check if the ARP address is in the ARP table. From Max Holtzberg.
- - Notify the socket layer from the network monitor if a connection is
- lost before the monitoring callback has been registered. From Max
- Holtzberg.
- - send(): Reset the send timeout when the data is ACKed, not when the
- data is sent. Remove conditions on checking for timeout. From Max
- Holtzberg.
- - Correct how the TCP/IP initial minimum MSS is calculated. Max
- Holtzberg.
- - TCP state machine: Move tcp connection into SYN_RCVD state after
- aception instead of bypassing and moving directly into ESTABLISHED.
- From Max Holtzberg.
- - Numerous fixes to the ENCX24J600 driver from Max Holtberg.
-
- * USB Drivers:
-
- - Change naming of SELFPOWERED and REMOTEWAKEUP to avoid name
- collisions. Prepend the name of the driver (for example
- CDCACM_SELFPOWERED).
- - CDC/ACM class driver: Change the interval for the interrupt
- endpoint from 0xff (invalid) to 10. This is not a critical
- change but will avoid a complaint from the Linux driver when
- it overrides the 0xff value.
-
- * ARM Cortex-A5:
-
- - Fix an error in data cache clean and invalidate functions: Fix of
- addresses to cache line boundaries.
-
- * Atmel AT91 SAMA5D3x Drivers:
-
- - Correct some inconsistencies in the way that USB configuration
- settings are used. This caused compilation errors in SAMA5 OHCI
- when USB debug was ON but USB host tracing was off.
- - When 480MHz UPLL is used to drive OHCI, it should have a divider
- of 10. However, that does not work. A divider of 5 does. Why?.
- - OHCI HCD: Fix a place where DMA-related data needed to be flushed
- to data cache; Fix another where a virtual address was being used
- in a register where a physical address was required.
- - HSMCI Driver: TX DMA disabled. It is just not reliable. No idea
- why. RX DMA is still used.
- - STM32F103C pinmapping corrections from David Sidrane.
-
- * Atmel SAMA5D3x-EK Board
-
- - Increase the number of pre-allocated watchdog timers. The default
- number of 4 was easily being exhausted in the more complex
- configurations.
-
- * STMicro STM32:
-
- - STM32 F4 DMA definitions: Typo fixes for UART7 and UART8 DMA
- configs. From Mike Smith.
- - DMA priority configuration corrections from Mike Smith.
- - Changes to the stm32_dmacapable API. In order to correctly
- verify that a buffer can be transferred, the transfer count and
- the CCR value are required. Implemented stm32_dmacapable for
- stm32f1xx devices. Enhanced stm32_dmacapable for stm32f2xx and
- stm32f4xx devices to check for additional conditions that will cause
- DMA to fail or lose data.
- - STM32 F1 DMA fix from David Sidrane: The DMA_CNDTRx register
- cannot be modified if the DMA channel is disabled.
-
- * STMicro STM32 Drivers:
-
- - Fix compilation errors from bad bit definitions in ADC and PWM
- register. From Martin Lederhilger.
- - DMA-related fixes to the SPI driver from Ken Pettit.
-
- * NXP LPC17xx Drivers:
-
- - Remove undefined spi_select() prototype. This was causing compile
- time warnings.
-
- * NXP LPC17xx Boards:
-
- - zkit-arm-1768: MMC/SD is on SPI, not SSP0. From Rashid Fatah.
-
- * C Library
-
- - scanf() fixes from kfrolov: 1) sscanf() function hangs in the
- following example: sscanf("2", "%u,%u,%u,%u", ...), 2) sscanf()
- returns incorrect number of parsed numbers if some arguments
- can't be parsed: sscanf("=2", "%u,%u,%u,%u",...)==1 instead of
- 0, and 3) using of char* instead of const char* in vsscanf
- function leads to warnings from GCC.
-
- * Build System
-
- - Dependency generation generation was broken for directories that
- keep objects in a sub-directory. The MKDEP tools now support a new
- argument that identifies the object file path.
- - tools/define.sh: 'cut' no longer works as it once did. Script
- adapted to observed behavior.
-
- * Applications:
-
- - Remove a warning from the NSH library when DHCP is not enabled.
- - Default NSH IP address should be 0x0a000001 (10.0.0.1), not
- 0xa0000001 (160.0.0.1). Ditto for the gateway.
- - Add some missing options to the OS test Kconfig file
- - Fix some bad conditional compilation in the USB monitor.
- - Fix default I2C frequency used by the I2C tool: 400KHz instead
- of 4MHz. Suggested by Max Kriegleder.
- - Increase stack size for the system/info command. Ken Petit
- reports that this simple command can exceed its 768 stack size
- under certain conditions. The size is marginal and has been
- increased to 1024 by default but is also now configurable.
- - apps/Makefile: Needs to include external/Make.defs if we want
- allow external applications to participate in the NuttX
- configuration. Suggested by gdi@embedders.org.
- - apps/netutils/telnetd: Missing argument to debug statement
- can cause crashes in certain error conditions. From David
- Sidrane.
- - apps/examples/can: Correct an error in a debug statement. From
- Martin Lederhilger.

+* File Systems:
- - procfs: Add support for a tiny procfs file system. The initial

- further in subsequent releases.
- - NXFFS: An initial attempt was made to integrate NXFFS with the NAND
- MTD driver. Changes were made to handle bad blocks. However, I
- later realized that NXFFS cannot handle NAND because the way that
- is re-writes blocks is incompatible with the NAND ECC handling.
- These changes were backed-out so as not to introduce turmoil, but
- can be re-enabled if needed via configuration option.
- - NXFFS: Make the start up scan of the media a configuration option.
- It just takes to long and is not really necessary! Those rare cases
- where the scan was helpful can be fixed using MDIOC_BULKERASE IOCTL
- command.

+Efforts In Progress. The following are features that are partially

- * kconfig-fronted Configuration:
-
- - Conversion of old configurations to use the kconfig-frontends
- tool is an ongoing effort that will continue for some time.
- At this time, only 50% of the configurations have been converted
- to use the kconfig-frontends tools.
-
-Bugfixes (see the ChangeLog for details). Some of these are very important:
-
- * File Systems
-
- - FAT: In one error return case, the error return value was not being
- set, making the failure look like success. From David Sidrane.
- - mount: SMART FS must be included in the conditional compilation for
- the set of file systems that require block drivers. From Daniel
- Palmer.
- - SmartFS: Fixed a minor bug with SMART partition number reporting
- that would only be seen if both partition support and multi-root
- directory support are enabled at the same time. From Ken Pettit.
- - Deadlock: The inode semaphore must be re-entrant. Here is the re-
- entrant path that I found: (1) USB host connects to FLASH drive and
- creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is
- removed but /dev/sda is not destroyed because there is still a
- reference on the device because of the mount, (4) umount() is
- called, taking the inode semaphore, now the driver tries to destroy
- the block driver by calling unregister_blockdriver(). But (5)
- unregister_blockdriver() also takes the inode semaphore causing a
- deadlock if the inode semaphore is not re-entrant.
- - FAT: Fix a typo in the FAT16 formatting logic. Was this ever able to
- format a FAT16 volume?
-
- * MTD Drivers
-
- - MTD Partitions: Fix erase block vs page block confusion. From Ken
- Pettit
- - SST25 Serial Flash: Improved write performance by fixing a bug that
- prevented operation in the faster write mode. From David Sidrane.
-
- * USB Drivers:
-
- - USB MSC Device: pthread_join() does not work if called from a
- different task group than the pthread. This is correct behavior,
- but still a problem. The correct solution would be configure the
- USB MSC thread to a task, however, this workaround from David
- Sidrane plugs the hole for now.
- - USB CDC/ACM, USB MSC, and Composite Device Classes: Un-initialization
- logic caused re-use of a stale pointer. Changed to a two pass
- un-initialization for the case of the composite driver: Memory
- resources are not freed until the second un-initialization pass.
- From David Sidrane.
-
- * STMicro STM32 Drivers:
-
- - STM32 F1 USB Device: Fix some errors that cause crashes when the USB
- was disconnected. From David Sidrane.
- - STM32 F1 USB Device: Correct EP0 state handling logic when buffers
- larger than the EP0 packet size are sent. From David Sidrane.
- - STM32 F1 USB Device: The long outstanding bug involving the handling
- of OUT SETUP commands has been fixed in the STM32 F1 USB device
- driver by David Sidrane.
- - Kconfig: Add missing setup of CAN TSEG1 and TSEG2 values. From
- Martin Lederhilger.
-
- * Tools
-
- - tools/mkconfig.c: SMART FS must be included in the conditional
- compilation for the set of writable file systems. Noted by Daniel
- Palmer.
-
- * Applications:
-
- - apps/platform/Makefile: Was not dealing with the bin sub-directory
- correctly.
- - apps/system/composite/composite_main.c: The wrong handle was getting
- nullified. From David Sidrane.

-
- * ARMv7-M
-
- - Add support for high priority, nested interrupts. This change
- effects not only core ARMv-7M logic, but all ARMv7-M MCU logic:
- LM3S, LM4F, LPC17xx, LPC43xx, SAM3, SAM4, and STM32. See
- https://cwiki.apache.org/confluence/display/NUTTX/High+Performance%2C+Zero+Latency+Interrupts

- - Add the C11 thread.h header file
-
- * Configuration/Build System
-
- - Top level Makefile now supports qconfig and/or gconfig targets that

-
- * Applications
-
- - NSH: Refactor. Separate NSH command handling and command execution
- from NSH line parsing.
- - NSH: Will now support multiple commands on a command line, each
- separated with a semi-colon.
- - NSH: Add support of commands enclosed in back quotes as command
- arguments.
- - NSH: Can now handle arguments that are concatenations of constant
- strings, command return data, application return data, and
- environment variables.
- - NSH: Add true and false commands.
- - NSH: Add support for while-do-done and until-do-done loops. These
- only work when executing a script file because they depend on the
- ability to seek in the file to implement the looping behaviors.
- Can be conditionally compiled out to reduce footprint.
- - NSH: Loosen up if-then-else-fi syntax to allow a command to be on
- the same line as the then or else tokens like:
- "if true; then echo true; else echo false; fi". More like bash.
- - NSH: Add a break command that can be executed with a loop to
- terminate the loop immediately.
-
- - system/inifile: A simple .INI file parser.
- - system/vi: Add support for a tiny, VI work-alike editor. This is
- a minimal full screen editor that works with a terminal emulator
- that using VT100 commands.

- doing nothing! It turns out that that is not really important
- because up_disable_irq() is not really used for that purpose. But
- some spurions STM32 ADC interrupts have been reported to me and this
- turned out to be the cause in that case. Thanks to Manuel Stühn for
- the tip.

NuttX-7.1
---------
The 101st release of NuttX, Version 7.1, was made on March 15, 2014,
-and is available for download from the SourceForge website. Note
-that release consists of two tarballs: nuttx-7.1.tar.gz and
-apps-7.1.tar.gz. Both may be needed (see the top-level nuttx/README.txt
+and is available for download from the SourceForge website. Note
+that release consists of two tarballs: nuttx-7.1.tar.gz and
+apps-7.1.tar.gz. Both may be needed (see the top-level nuttx/README.txt
file for build information).
- The previous NuttX version was 6.33. The NuttX minor version number is
- incremented on each release, but the major version number is incremented
- only when an incompatibility with previous versions is included in the
- release. In this case, the legacy, manual configuration is no longer
- supported by the NuttX build system beginning with NuttX 7.1. Only the
- newer configurations generated by the kconfig-frontends tools will generate
- viable NuttX configurations.
-
- All board configurations in the NuttX source tree have been converted to
- use the newer configuration, but if you have some older style configurations
- for you board, you will need to convert those configurations to use the
- kconfig-frontends tools before taking any new code from the repository. See
- https://cwiki.apache.org/confluence/display/NUTTX/Converting+Legacy+Configurations+to+Use+kconfig-mconf
- for some guidelines.
