S32K324 : Debugger and Peripheral Clock

[sreekanthkn]

Hello,

I am using S32K324 controller and PE micro multilink debugger. I had a problem in running the software without debugger. I was able to run the software with debugger connected but when I tried to run the SW without debugger as standalone, software was not running. After spending some time investigating, I enabled the peripheral clock for all the peripherals in the SW and then I was able to run the SW without debugger also.

My question is how PE micro debugger impacts the clock of the peripherals?

Thanks in advance.

Hi Lukas,

thanks for your reply.

This option is disabled in my setup. Unfortunately I can not share the project with you. Is there any other pointers I can check?

Hi,

you can try to attach the debugger to a running target, so you can check state of the device. Take a look at this thread, for example:

https://community.nxp.com/t5/S32-Design-Studio/How-attach-to-running-program/m-p/1030375

Another thing - I would try to enable the clocks one by one to see what makes the difference exactly.

Regards,

Lukas

Hi Lukas,

execution is stopped with a bus fault originated from DMA code.

Hi Sreekanth,

Pemicro uses *.mac file to perform some basic steps for debugging. You can find it at this path:

c:\NXP\S32DS.3.4\eclipse\plugins\com.pemicro.debug.gdbjtag.pne_5.2.6.202206301831\win32\gdi\P&E\supportFiles_ARM\NXP\S32K3xx\S32K324.mac

But it should be disabled by default. Could you check in debug configurations if it is disabled?

If this doesn't help, is it possible to provide simple project to reproduce the issue?

Lukas
