I'm trying to configure various GPIO in the AL and AH GPIO ports as outputs, using Tresos, on my S32K344EVB.
From the RTD examples, PTA29 is configured to drive the red LED, and I've successfully configured PTA30 and PTA31 to drive the green and blue LEDs respectively. I've tried to configure other GPIO in the A-ports, such as GPIO21, as outputs but they're stuck low. I haven't had this problem with the GPIO B-ports.
Any insight on why I can't configure the A-ports would be appreciated. Thank you.
