AM623: ESM error

Part Number: AM623

After the system starts up normally and enters the terminal console, it runs for a period of time and automatically restarts during operation. The chip model is am62x and the SDK version is 10.01.10.04. What is the reason for the restart? Which registers can be read to further troubleshoot the problem?
Read the register 0x431A178h, and there is the following output log:

1  [system reboot time: 1970-01-01 00:00:02] POR Reset, Register_value: 0x00000000. Note: The ZLG and FORLINX core boards can't distinguish between an external watchdog reset and a power-on reset.

    Hi,

    Is this a TI EVM or your custom board? Which power supply are using with your board. We have seen similar issues when the power supply was too low for the SoC to function. 

    Also, are you enabling Wdg module and ESM module in either your MCU or A53 cores. Can you share the value of the following registers:

    0x4518170

    0x43018170
