Resolved! STM32L4xx board has GPIO pin 5 on two different ports (GPIOA and GPIOB) that need to interrupt at different phases of processing. How to initialize PA5 to interrupt initially and the switch to PB5 until done and switch back?

EE designed the board with both pins in use and both needing to wake up from STOP2. At start PA5 must be used to awake. Once awake, switch interrupt to PB5 for normal processing. When normal processing is done, switch back to PA5 and enter STOP2. ...

Faulty pins?

Hey, I made some simple code for my STM32L053C8 Discovery kit to toggle GPIO pins which are connected to LEDs. I used PA0 PA1 and PA2 pins and only PA0 pin responded. Then I turned all GPIO pins high and using LED found some more pins which didn't tu...
