Virtual port is not activated after DFU OTA

[shay]

Hi

I succeeded to run the DFU OTA process and updated only the application. Application is running OK

The problem is that after repower the application is running but debugger is not and I do not get the usb virtual com port activating.

Can someone explain why please?

Thanks

Hi,

It might be that your debugger firmware is gone. Can you check if this is the case?
