Hello,


That means you had a voltage ripple, and eventually the ripple exceed the max value of operating condition that triggers the device reset(you observed as device shutdown).

Please review your power delivery design for your PCB and make sure the decoupling capacitors are sufficient to supply the current required during ramp up and configuration.


Please use PDN tool to determine the power needed and how many decoupling required in your design.
