s32k31x recovery Mode

[hagoo]

hello,

I disabled recovery Mode in S32k31x.

After generating DES once and T32 was attached, THEN S32k31x runs an infinite loop at 2040012C

That is the address value when entering recovery mode.

Do you know why it stays at that address value even after disabling the recovery mode?

If you check DCM_GPR_DCMRWP1 when s32k31x stay at that address value, you can see that it is disabled in C.

Hi @hagoo 

that's strange, I can see no problem on my side.

When I didn't disabled the recovery mode, I reached the endless loop after 8 functional resets which were generated by code. When I disabled the recovery mode, I can trigger more functional resets, no recovery mode is entered:

After destructive reset (POR), the application is still working.

Regards,

Lukas
