-# Getting Started with nsh configuration
-1. Download and install toolchain
-
- $ curl https://static.dev.sifive.com/dev-tools/riscv64-unknown-elf-gcc-8.3.0-2019.08.0-x86_64-linux-ubuntu14.tar.gz
-
-2. Download flash tools
- There are multiple tools that can be used, but option (a) is recommended.
- a. blflash -- cross platform open-source (recommended)
- curl -L -o blflash https://github.com/spacemeowx2/blflash/releases/download/v0.3.0/blflash-linux-amd64
- chmod +x ./blflash
-
- b. Bouffalo Lab flash tools (official)
- https://github.com/bouffalolab/flash_tools.git
-
-3. Configure and build NuttX
-
- $ mkdir ./nuttx; cd ./nuttx
- $ git clone https://github.com/apache/incubator-nuttx.git nuttx
- $ git clone https://github.com/apache/incubator-nuttx-apps.git apps
- $ cd nuttx
- $ make distclean
- $ ./tools/configure.sh bl602evb:nsh
- $ make -j
-
-4. Connect bl602 and computer via USB
-
-5. Flash
- Use option (a) or (b) based on tool selection in section 2.
- a. Using blflash
- Place the board in bootloader mode
- bl602evb: Jumper IO8 to HI and press reset
- DT-BL10: Press and hold D8, press and release EN, release D8
-
- $ blflash flash nuttx.bin --port /dev/ttyUSB0

- b Using BL flash_tools
- Run flash tools, select the nuttx.bin generated in the previous step in the
- Firmware bin field, and refer to the document for the settings of the remaining fields.
-
-6. Run connect terminal to UART (default baudrate 2000000)
- $ screen /dev/ttyUSB0 2000000
-7. Reset Device
- bl602evb: Press reset
- DT-BL10: Press and release EN
-8. NSH should appear on console
-
-
-# Using openocd and gdb:
-This guide is focused on the bl602evb board. See the reference manual for
-how to connect to the JTAG interface for other boards.
-
-1. Make sure you are running a recently built version of openocd. The packaged
-versions are very old, and will likely not work. https://github.com/ntfreak/openocd
-
-
-2. Create a openocd-bl602.cfg file
