Running mbed on custom PCB (STM32L496)

Hello,

I am programming STM32L496ZGTx on a custom PCB. In mbed I picked "NUCLEO L496ZG" platform hoping the pin mappings and settings would be the same.

However I am not able to run the most basic blink GPIO example (turning on external LED). It just does nothing. Double checked correct pins settings.

Custom PCB and MCU are OK, I tried a code with the same meaning using classical CubeMX-Atollic TRUEStudio and everything works OK, so hardware is OK and so is programming .bin files. Internal oscillator is used.

No idea what is the issue or how to fix it. Please share any ideas you might have.
