David,

Thanks for the help. Here are the relevant schematic portions. We use a COM Express type 6 CPU module from Congatec, so some of the associated circuitry is on their board.

The schematic looks ok, do you have any decoupling caps on the 3.3V supply, what particular issue are you seeing?

Thanks
David
