+README
+======
+
+ This README file provides information about the port of NuttX to the Teensy 4.x board. This board features the
+ MIMXRT1062DVL6A MCU. Some of the features of this board include:
+
+ o Processor
+
+ - MIMXRT1062DVL6A processor
+
+ o Memory
+
+ - 1 Mb RAM memory
+ - 2 Mb QSPI Flash
+ - 1 SDIO (4 bit) native SD
+
+ o Connectivity
+
+ - Micro USB host
+ - CAN transceivers
+ - 41 digital pins
+ - 14 analog pins, 2 ADCs on chip
+
+Contents
+========
+
+ o LEDs
+ o Configurations
+ - Configuration sub-directories
+
+LEDs and buttons
+================
+
+ LEDs
+ ----
+
+ There are two LED status indicators located on the Teensy-4.x board.
+ The functions of these LEDs include:
+
+ - RED LED (loading status)
+ - dim: ready
+ - bright: writing
+ - blink: no USB
+ - USER LED(D8)
+
+ Only a single LED, D8, is under software control.
+
+ This LED is not used by the board port unless CONFIG_ARCH_LEDS is
+ defined. In that case, the usage by the board port is defined in
+ include/board.h and src/imxrt_autoleds.c. The LED is used to encode
+ OS-related events as follows:
+
+ ------------------- ----------------------- ------
+ SYMBOL Meaning LED
+ ------------------- ----------------------- ------
+ LED_STARTED NuttX has been started OFF
+ LED_HEAPALLOCATE Heap has been allocated OFF
+ LED_IRQSENABLED Interrupts enabled OFF
+ LED_STACKCREATED Idle stack created ON
+ LED_INIRQ In an interrupt N/C
+ LED_SIGNAL In a signal handler N/C
+ LED_ASSERTION An assertion failed N/C
+ LED_PANIC The system has crashed FLASH
+
+ Thus if the LED is statically on, NuttX has successfully booted and is,
+ apparently, running normally. If the LED is flashing at approximately
+ 2Hz, then a fatal error has been detected and the system has halted.
+
+Configurations
+==============
+
+ Information Common to All Configurations
+ ----------------------------------------
+ Each Teensy-4.x configuration is maintained in a sub-directory and
+ can be selected as follow:
+
+ tools/configure.sh [OPTIONS] teensy-4.x:<subdir>
+
+ Where typical options are -l to configure to build on Linux or -c to
+ configure for Cygwin under Linux. 'tools/configure.sh -h' will show
+ you all of the options.
+
+ Before building, make sure the PATH environment variable include the
+ correct path to the directory than holds your toolchain binaries.
+
+ And then build NuttX by simply typing the following. At the conclusion of
+ the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
+
+ make
+
+ The <subdir> that is provided above as an argument to the tools/configure.sh
+ must be is one of the following.
+
+ NOTES:
+
+ 1. These configurations use the mconf-based configuration tool. To
+ change any of these configurations using that tool, you should:
+
+ a. Build and install the kconfig-mconf tool. See nuttx/README.txt
+ see additional README.txt files in the NuttX tools repository.
+
+ b. Execute 'make menuconfig' in nuttx/ in order to start the
+ reconfiguration process.
+
+ 2. All of these configurations are set up to build under Windows using the
+ "GNU Tools for ARM Embedded Processors" that is maintained by ARM
+ (unless stated otherwise in the description of the configuration).
+
+ https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
+
+ That toolchain selection can easily be reconfigured using
+ 'make menuconfig'. Here are the relevant current settings:
+
+ Build Setup:
+ CONFIG_HOST_WINDOWS=y : Window environment
+ CONFIG_WINDOWS_CYGWIN=y : Cywin under Windows
+
+ System Type -> Toolchain:
+ CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : GNU ARM EABI toolchain
+
+Configuration sub-directories
+-----------------------------
+
+
+ nsh-4.0:
+
+ Configures the NuttShell (nsh) located at examples/nsh for Teensy 4.0.
+ This NSH configuration is focused on low level, command-line driver testing.
+ Built-in applications are supported, but none are enabled. NutShells then
+ runs on UART6: Pin 0 is RX and pin 1 is TX
+
+ nsh-4.1:
+
+ Configures the NuttShell (nsh) located at examples/nsh for Teensy 4.1.
+ This NSH configuration is focused on low level, command-line driver testing.
+ Built-in applications are supported, but none are enabled. NutShells then
+ runs on UART1: Pin 24 is TX and pin 25 is RX
+
+ can-4.1:
+
+ This is an nsh configuration (see above) for Teensy-4.x with added support of
+ CAN driver. FlexCAN3 is chosen as default, the change can be made at System
+ type peripheral selection.
+
+ Bitrate and sample point can be also changed at System type peripheral selection,
+ basic values are 1 MHz for bitrate and 0.80 for sample point. The FlexCAN driver
+ for imxrt runs at 80 MHz clock frequency.
+
+ The configuration also includes CAN utilities as candump and cansend.
+
+ CAN_FD supported but not enabled. For CAN_FD please select following:
+
+ CAN_FD = y
+ NET_CAN_CANFD = y
+ NET_CAN_SOCK_OPTS = y
+
+ This configuration can be easily changed to work with Teensy 4.0 by
+ selecting CONFIG_TEENSY_40=y.
+
+ netnsh-4.1:
+
+ This configuration is similar to the nsh configuration except that is
+ has networking enabled, both IPv4 and IPv6. This NSH configuration is
+ focused on network-related testing.
+
+ This configuration cannot be changed to Teensy 4.0 as this board does
+ not have Ethernet capability.
+
+ sd-4.1
+
+ This is an nsh configuration (see above) for Teensy-4.x with added support of
+ connecting micro SD card.
+
+ You can mount micro SD card by "mount -t vfat /dev/mmcsd0 /mnt"
+
+ This configuration cannot be changed to Teensy 4.0 as this board does
+ not have micro SD card slot.

+ * beginning at 0x2020:0000. Neither DTCM or SDRAM are used in this

+ *
+ * The user and kernel space partitions will be spanned with a single

+ * The solution to this wasted memory is to (1) use more than one region to
+ * span the user spaces, or (2) poke holes in a larger region (via sub-
+ * regions) to trim it to fit better.
+ *
+ * A detailed memory map for the 512KB SRAM region is as follows:
+ *
+ * 0x2020 0000: Kernel .data region. Typical size: 0.1KB
+ * ------ ---- Kernel .bss region. Typical size: 1.8KB
+ * 0x2020 0800: Kernel IDLE thread stack (approximate). Size is
+ * determined by CONFIG_IDLETHREAD_STACKSIZE and
+ * adjustments for alignment. Typical is 1KB.
+ * ------ ---- Padded to 4KB
+ * 0x2040 0000: User .data region. Size is variable.
+ * ------- ---- User .bss region Size is variable.
+ * 0x2042 0000: Beginning of kernel heap. Size determined by

+/* There are four LED status indicators located on the EVK Board. The
+ * functions of these LEDs include:
+ *
+ * - Main Power Supply(D3)??
+ * Green: DC 5V main supply is normal.
+ * Red: J2 input voltage is over 5.6V.
+ * Off: The board is not powered.
+ * - Reset RED LED(D21)??
+ * - OpenSDA LED(D20)??
+ * - USER LED(D8)
+ *
+ * Only a single LED, D8, is under software control.
+ *
+ * This LED is not used by the board port unless CONFIG_ARCH_LEDS is
+ * defined. In that case, the usage by the board port is defined in
+ * include/board.h and src/imxrt_autoleds.c. The LED is used to encode
+ * OS-related events as follows:
+ *
+ * -------------------- ----------------------- ------
+ * SYMBOL Meaning LED
+ * -------------------- ----------------------- ------
+ *
+ * LED_STARTED 0 NuttX has been started OFF
+ * LED_HEAPALLOCATE 0 Heap has been allocated OFF
+ * LED_IRQSENABLED 0 Interrupts enabled OFF
+ * LED_STACKCREATED 1 Idle stack created ON
+ * LED_INIRQ 2 In an interrupt N/C
+ * LED_SIGNAL 2 In a signal handler N/C
+ * LED_ASSERTION 2 An assertion failed N/C
+ * LED_PANIC 3 The system has crashed FLASH
+ * LED_IDLE Not used
+ *
+ * Thus if the LED is statically on, NuttX has successfully booted and is,
+ * apparently, running normally. If the LED is flashing at approximately
+ * 2Hz, then a fatal error has been detected and the system has halted.

+ * Name: arch_phy_irq
+ *
+ * Description:
+ * This function may be called to register an interrupt handler that will
+ * be called when a PHY interrupt occurs. This function both attaches
+ * the interrupt handler and enables the interrupt if 'handler' is non-
+ * NULL. If handler is NULL, then the interrupt is detached and disabled
+ * instead.
+ *
+ * The PHY interrupt is always disabled upon return. The caller must
+ * call back through the enable function point to control the state of
+ * the interrupt.
+ *
+ * This interrupt may or may not be available on a given platform depending
+ * on how the network hardware architecture is implemented. In a typical
+ * case, the PHY interrupt is provided to board-level logic as a GPIO
+ * interrupt (in which case this is a board-specific interface and really
+ * should be called board_phy_irq()); In other cases, the PHY interrupt
+ * may be cause by the chip's MAC logic (in which case arch_phy_irq()) is
+ * an appropriate name. Other other boards, there may be no PHY interrupts
+ * available at all. If client attachable PHY interrupts are available
+ * from the board or from the chip, then CONFIG_ARCH_PHY_INTERRUPT should
+ * be defined to indicate that fact.
+ *
+ * Typical usage:
+ * a. OS service logic (not application logic*) attaches to the PHY
+ * PHY interrupt and enables the PHY interrupt.
+ * b. When the PHY interrupt occurs: (1) the interrupt should be
+ * disabled and () work should be scheduled on the worker thread (or
+ * perhaps a dedicated application thread).
+ * c. That worker thread should use the SIOCGMIIPHY, SIOCGMIIREG,
+ * and SIOCSMIIREG ioctl calls** to communicate with the PHY,
+ * determine what network event took place (Link Up/Down?), and
+ * take the appropriate actions.
+ * d. It should then interact the PHY to clear any pending
+ * interrupts, then re-enable the PHY interrupt.
+ *
+ * * This is an OS internal interface and should not be used from
+ * application space. Rather applications should use the SIOCMIISIG
+ * ioctl to receive a signal when a PHY event occurs.
+ * ** This interrupt is really of no use if the Ethernet MAC driver
+ * does not support these ioctl calls.
+ *
+ * Input Parameters:
+ * intf - Identifies the network interface. For example "eth0". Only
+ * useful on platforms that support multiple Ethernet interfaces
+ * and, hence, multiple PHYs and PHY interrupts.
+ * handler - The client interrupt handler to be invoked when the PHY
+ * asserts an interrupt. Must reside in OS space, but can
+ * signal tasks in user space. A value of NULL can be passed
+ * in order to detach and disable the PHY interrupt.
+ * arg - The argument that will accompany the interrupt
+ * enable - A function pointer that be unused to enable or disable the
+ * PHY interrupt.
+ *
+ * Returned Value:
+ * Zero (OK) returned on success; a negated errno value is returned on
+ * failure.
