Jlink fails to debug imx93

[leoX]

When using JLink to debug the M33 core of i.MX93, after setting breakpoints, it seems only the PC pointer is halted, while various internal counters continue counting, preventing normal debugging. What are the solutions for this issue?Thank you for ansering!

Hi,

Can you share the screenshot of  various internal counters? 

Did you set the m33 download mode?

Thank you for your response! I am reading tstmr in a task to calculate the task's execution cycle, but if I add a breakpoint, the calculated cycle increases, indicating that the system counter continues to count when I add a breakpoint. Also, I am starting the M core through the A core. Does setting the download mode for M33 help?

Best Regards

Hi @leoX 

My test is based on single M33 and Jlink, did you boot M33 with remoteproc?

Yes, and I tried on single M33 core, the system counter can't be halted as before. I can't find the reason.

Best Regards.
