Getting Started with NuttX – Nucleo STM32F303 (Arch Linux)

Here we will try to set up a functional Nuttx environment on a STM32F303 Nucleo-64 evaluation board on Arch Linux OS.

We will install the required software components, configure the board in order to be able to display the "hello world !" string on a serial terminal to the emulated ST-LINK/V2-1 serial port (through the USB cable).

Installing the ARM tool chain

Install the following Arch software packages:

...

Packaging from AUR, despite being very simple, is out of scope of this document. Please refer to Arch Wiki and install these above packages.

Install Nuttx

$ mkdir nucleo; cd nucleo
$ git clone https://bitbucket.org/nuttx/nuttx
$ git clone https://bitbucket.org/nuttx/apps

$ cd nuttx
$ tools/configure.sh nucleo-f303re:hello

...

One can see the firmware nuttx.hex has been successfully generated.

Flash & debug with openocd and gdb

The good thing with the nucleo kit is that it embarks the latest st-link/V2-1 which may be used as a JTAG programmer/debugger, and also a USB to serial bridge which is already routed to the STM32 UART1. Therefore one can use it to redirect sdtout and the Nuttx console.

Connect to the STLINK serial console

Open a new terminal and run the mintermminiterm:

$ miniterm.py /dev/ttyACM0 115200
miniterm.py /dev/ttyACM0 115200
--- Miniterm on /dev/ttyACM0  115200,8,N,1 ---
--- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---

Congratulation! You are started with Nuttx NuttX!
