Hi Marek,

Pin mux settings has error, set EMACIO[1-8] [10-13] from 3 to 2, then usb works,

=> usb start
starting USB...
USB0: Core Release: 2.93a
scanning bus 0 for devices... 2 USB Device(s) found
=> usb tree
USB device tree:
1 Hub (480 Mb/s, 0mA)
| U-Boot Root Hub
|
+-2 Mass Storage (480 Mb/s, 98mA)
Generic USB Storage 000000000272
