How to debug at the sleep state

HaileyByun — Sun, 13 Oct 2024 07:59:29 GMT

Hello. I'm using S32K312 and I'd like to know how to debug at the sleep state.

I'm using Trace32 and canoe. And I can't debug at the sleep state because of hardfault.

How can I debug?

Have you referred to the Low-power debug handshake protocol chapter of S32K3xx Low Power Management.pdf and S32K3XXRM.pdf?

Best Regards,
Robin

I got running(power down) state but I can't see B:List window as you can see this picture.

Did you add the command "SYStem.Option PWRDWNRecover ON" to Lauterbach download script?

I am able to run S32K344_GPIO_Wkup_S32DS_3_4_RTD_LLD_2_0.elf on S32K3X4EVB-Q257. This elf is from S32K3 Low Power Management AN and demos.

yes I did.

So as you can see the picture that I uploaded, there's "(powerdown)" in the running state.

But I can't see B:List window.

Are there anything else that I should do?

I'm not sure if you can't see B::List main
Please refer to the attached video

I can't see the "B::List" window like you. But I can't set break point. When I try to set breakpoint on B::List window, and I can only see the message,"Chip powered down", on T32.

And also I can't see anything on"B:Var Watch" window.
