We are bringing up a new board with the iMX8MP.
We can load and run flash.bin via uuu over USB port 2 using USB high speed 480 Mbps.
We have USB port 1 connected through a TI USB port isolator "ISO USB 111" which only passes USB low speed or USB full speed 12Mbps. uuu fails after 1% to 3% shown and ends with LIBUSB_ERROR_PIPE.
Using a scope, the signals at the iMX8MP side of the isolator look very clean.
Does the iMX8MP boot rom support USB full speed over the serial download protocol?
Thanks.
