Re: Bootloader issues?

Sorry to take up more of your time but can you confirm there is nothing wrong with the messages I have,

I did read the document and noted the reasons but its not a full match to my messages.

Everything does seem to work fine now but just curious.

Thank you

Re: Bootloader-Update @ CM4 Lite + I/O-Board

Hi Mexx,

thanX FYI! I Read somethig about in the Datasheet:
The micro USB connector is designed to enable the CM4 to be updated via rpiboot. When a micro USB cable is plugged in
the USB hub is automatically disabled, so the CM4 USB 2.0 port becomes a USB device.
