Debugging with UART

Connecting

There is a debug console accessible through the board UART. Like the flashing process, you will need an USB to TTL FTDI Adapter with 3.3V support.

Connect the TTL Adapter using only the following pins: GND, RX and TX (do NOT connect VCC / +5V / +3.3V etc) Speed is 115200 8N1
