.. note:: west flash requires SEGGER J-Link software_ and pylink_ Python module to be installed on you host computer.

Open a serial terminal (minicom, putty, etc.) with the following settings:

  • Speed: 115200
  • Data: 8 bits
  • Parity: None
  • Stop bits: 1

Reset the board and you should be able to see on the corresponding Serial Port the following message:
