I have a Potenta H7 and need to use serial ports 1-3. 1 and 3 are responding and sending data but not serial 2. Exact same code with each: Serial.begin(), serial.available(), etc...
What is it about serial UART 2 on an H7?
Found the answer on this forum. Had to add this code so that UART 2 used the correct pins: UART GPS_UART2(PG_14, PG_9, NC, NC);
