Debug message in core 0 and core 1

I’m new to embedded systems and I’m trying to debug the NXP FRDM-MCXN947. We have two cores, and I can see the messages from Core 0 on one of the COM ports. However, I’m unable to see the messages from Core 1. Is there a jumper configuration needed to view the Core 1 console?

Hi,

The core1 can use the uart to communicate to outside world as the core0 does.

Pls refer to the AN14150, it uses mutex mechanism to guarantee the integrity of the message from both core0 and 1.

Hope it can help you
