TPS53622: Invalid Command Status

Part Number: TPS53622

Team,

Have you ever seen invalid command status though tps53622A can boot up normally? Just worry about if something goes wrong. Do you have any idea about it?

Thanks.

    Hi,

    CML-Invalid Command won't affect any regulation behaviors. It was logged due to some PMBus communication error. There are several scenarios could cause it. For example, if the GUI keeps polling the data even before supplying 3.3V, then it's very likely the controller will get incomplete PMBus command when it is powered up.
