Hi,

    In Standby mode of NxpS32k344,the last step is to execute __WFI() instruction for waiting interrupt. But I execute that instruction program goes to out of memory area and lost connection with the target processor.

Do you develop your own debugger / programmer?

If you use Segger / Lauterbach / PEMicro debugger, please contact the vendor.

Daniel

Hi @Vamsi421,

You would need to implement Low-power debug handshake protocol (RM, Section 81.9).
