Board: STM32F3discovery
The STM32F3-discovery is cheap evaluation board designed by ST for pushing the STM32F3 microcontoller to a broad audience. It features an STM32F303VC microcontroller with 48Kb of RAM and 256Kb flash memory running with up to 72MHz. Addionially it provides USB host capabilities, 8 LEDs and sensors for a 9-degree of freedom initial measurement unit (3-axis accelerometer, 3-axis gyro and 3-axis magnetometer).
The board does however not provide any radio capabilities, radio devices have to be connected externally via I2C, SPI, UART or similar.

The STM32F3discovery board includes an on-board ST-LINK V2 programmer. To program the board you just need to connect a micro-USB cable to the USB port that is centered on the top of the board. You can then either write software into the mircrocontrollers flash memory using one of the supported IDE's (e.g. Atollic Studio) or by using the free commandline tool 'st-flash'.
- First of all you have to download the st-flash tool from texane's github repository:
# git clone https://github.com/TODO/blubb.git stlink
- Change into the new directory:
# cd stlink
- Build the st-flash tool
# ./configure
# make
For this step you have to have a working build-environment installed, for debian/ubuntu you can do this by installing the build-essential package.
- Add the
st-flashandst-utiltools to your bin-path
-
Connect your discovery board to your pc
-
After you have successfully compiled RIOT and your application, just type
# make flash
This will run the st-flash utility and upload your compiled project to your discovery board.
You can alternatively flash your discovery board manually by using the st-flash utility directly:
$ st-flash [PRJDIR]/bin/stm32f3discovery/[PRJNAME].hex 0x08000000
