Hello community!

IN the FS32K144HFT0VLLT project, I found that the MCU would occasionally reset and then I found the value of the RCM->SRS register is 0x20 when reset happened.It means WDOG out of TIME.How can I quickly locate the cause example somewhere crash?

Any help would be greatly appreciated. Thank you!

Hi @dzkk

The Watchdog timer is enabled by default be sure to refresh it or disable it.

If the WDOG is enabled is going to cause a reset to the MCU if it is not refreshed.
