I have a issue with j-link debug.
My platform is S32K148, the debug tools is j-link, the 4 pin connect, GND-VCC-SWD-CLK.

But one time, I debug my code, maybe the program is not valid, the program run out of track, and pop up message.

From then on, the j-link can not connect with platform.

I have try below procedure

1. plug out power and plug in

The program can run part, but after part, disorder

2. make reset to low when connecting, also fail.

3. I have mark the SWD function when VLPS mode, I doubt the program have jump to VLPS.


For this issue, how to fix it, please help.
