Dear NXP Support,
I am currently using TRACE32 to debug an S32K312 device.
The S32K312 is configured with two cores (Core 0 and Core 1). I can debug Core 0 without any issues, but I am unable to debug code running on Core 1.
As shown in the attached screenshot, I set a breakpoint in the source code executed by Core 1. I also added a counter variable, and I can see that its value keeps increasing, which indicates that the code is indeed running. However, the breakpoint is never hit.
Could you please advise how to properly configure TRACE32 to debug both Core 0 and Core 1?
If there are any additional settings or initialization steps required for multi-core debugging on the S32K312, I would appreciate your guidance.
Here is my file cmm

Hi @NghiaLX308
Are we really talking about S32K312? Because this is single core device:
