Hi @Jorn,
I was able to reproduce the error on my side, I got the same hard fault in the assembly code. My assumptions are:
- The UART is being used already, so we need to specify to the RDC (resource domain controller) that we want to use it on the Cortex-M side.
- Or, the UART is not initialized yet, so we need to initialize it first.
I’m not sure right now what is happening, but I will update you if I manage to make progress.
Best Regards,
Hiago.
