Hello,

Are you using a custom board or Ti EVM? If it's a custom board then are you using the same PMIC as TI EVM?

Let us know the above details.

Best Regards,

The PMIC has its watchdog enabled by default. Just start "petting" the watchdog over the I2C2 interface, GPIO1 and GPIO2 and it is good to go.
