Following instructions specifies how to flash the firmware onto WisTrio board from a Linux host machine:
$ git clone https://git.code.sf.net/p/stm32flash/code stm32flash-code $ cd stm32flash-code $ make $ sudo make install

$ sudo stm32flash -b 115200 -w ./Firmware/RAK811_HF_trackerboard_V188.8.131.52.bin -v -g 0x08000000 /dev/ttyUSB0
/dev/ttyUSB0is the serial port exposed by WisTrio
- Once the firmware is flashed, unlink J12 and connect to the WisTrio serial port using minicom
$ sudo minicom -D /dev/ttyUSB0
