There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.
Thanks

I don’t see anything related to UART in your log.

Is that CDC driver not able to work related to your device? Or you don’t know what I am talking about?
