    Hi,

    You can check the value RESET_SRC_STAT register from CTRL MMR section to know the reason for the reset.
    Please find the register details captured below.

    ok Thank you
    How to trace which process is killed while rebooting?

    How read the register CTRLMMR_WKUP_RESET_SRC_STAT to get the reset reason?

    Are you using Linux HLOS? If you try enabling coredump logging and check in the next boot, which process created the segmentation fault.

    You can read from the Linux HLOS root prompt using the devmem2 command.

    Thank you for your reply

    We are not using Linux HLOS, we are using qnx8.0 and FREERTOS
    How to enable coredump logs ?
    Will it give all the processes and threads information?

    we are using qnx8.0 and FREERTOS, how can we read the register CTRLMMR_WKUP_RESET_SRC_STAT?

    You can read the "CTRLMMR_WKUP_RESET_SRC_STAT" register from one of your applications and print to the debug terminal, and check in every boot what is the reason for the reset.

    QNX, please reach out to QNX on how to enable core dumps on QNX8.0.

    On FREERTOS, we are not logging the crashes.

    What is the reason for suspecting some application crashes? It will not reset the SoC. PMIC can only reset the SoC, or if any watchdog is implemented in the application, and trigger a SoC reset via PMIC.
