Hi @vix,
I made some tests and made an update to this thread: Verdin IMX8MM, hardfault when initializing UART on M4 core - #9 by hfranco.tx
Please check my last answer. I’m seeing the exact same thing on the Plus, I’m trying to check what is causing this issue with my JTAG probe now.
I’ll update you here and in the other ticket if I’m able to make progress.
Best Regards,
Hiago.
