Flashing the device
Flashing the Board Using OpenOCD
The ST Nucleo-F334R8 board includes an on-board ST-LINK V2 programmer. The easiest way to program the board is to use OpenOCD. Once you have installed OpenOCD (look here for installation instructions), you can flash the board simply by typing
and debug via GDB by simply typing
Flashing the Board Using ST-LINK Removable Media
On-board ST-LINK programmer provides via composite USB device removable media. Copying the HEX file causes reprogramming of the board. This task could be performed manually; however, the cpy2remed (copy to removable media) PROGRAMMER script does this automatically. To program board in this manner, use the command:
- Note
- This PROGRAMMER requires ST-LINK firmware 2.37.26 or newer. Firmware updates could be found on this STM webpage.
Accessing RIOT shell
Default RIOT shell access utilize VCP (Virtual COM Port) via USB interface, provided by integrated ST-LINK programmer. ST-LINK is connected to the microcontroller USART2.
The default baud rate is 115200.
Supported Toolchains
For using the ST Nucleo-F334R8 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
