I have a customer develop a board based on 7z010, everything is ok except the usb port, they found during the linux boot, can not detect any u-disk information. they also try it on microzed , both the same.
we also use a code try to read the PHY ID, return nothing, both on microzed and customer board.
Customer's board design is the same as microzed, except the number of layers. We have test the power,reset, everything ok.
