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:
make BOARD=stm32l476g-disco PROGRAMMER=cpy2remed flash
@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates can 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.
