Serial Console

At default serial console is available with Segger RTT driver. For access to the RTT console use this commands:

JLinkGDBServer -if SWD -device stm32h743zi -speed 16000
sudo socat -d -d PTY,link=/dev/ttyRTT0,raw,ignoreeof TCP:127.0.0.1:19021,reuseaddr
minicom -D /dev/ttyRTT0

An alternative option is to use the P4 connector and connect an external UART converter:
