S32K344 can connect Jlink but not debug with Jlink or PE

[MountQomolangmaclimber]

Hi everyone,

I met a problem with my S32K344. It can connect JLINK and can be erased via JLINK. But it cannot  neither debug with JLINK or PE, nor run programme normally. For example, there is a programme about LED twinkling, I download it in S32K344 via JLINK, but the led does not work.

The cause may be follow:

In a project of S32K358, I used PE for debugging and forcibly changed the configuration of PE from S32K358 to S32K344. Then I clicked Dubug, which caused the chip to be unable to continue to be used normally.

The above is entirely due to personal negligence. I hope my S32K344 return to normal, but I have no choice.

So I ask everyone for help. Thank you!

Here are some pictures about debugging:

Then I connect it with Jlink:

Then I debug with PE, there are some pictures:

As you can see, I cannot debug with PE or Jlink. So confused.

If you have any solution or advice, please reply soon. Thank you!

Oh, although it can be debugged in IAR, but when I turn off the power, and turn on the power, it does not work normally. I doubt that IAR debugs my S32K344 in RAM not flash.

Amazing!

It can be debugged in IAR!
