Hello Xinyu and Robin,

I was facing same issue and going through comments on software forum, As I am looking into older comments on forum in future someone like me may reach this thread and he might get benefitted from my comment so adding it to this thread.

I found that issue was present with my PE micro hardware (It was faulty), I was able to find root cause with Kinetis Recovery utility tool.

Hi xinyu1650,

Have you check the connections and power?

Have you successfully program the chip before?

Please observe the waveform of the RESET pin with an oscilloscope and upload a picture. If there is a periodic pulse, please let me know the period of the pulse.

Have you tried to using P&E Recovery Utility halt MCU by refer to: https://community.nxp.com/t5/S32K/Can-t-use-PEmicro-debugger-with-S32K118EVB2-Q048/td-p/1376204

Best Regards,
Robin
