Hello,
I am using Atmel AT91SAM9263-EK and running u-boot 1.1.5, it fails to recognize a USB key of size 1GB and formatted in FAT.
Yep, known problem.
This is what is happening: U-boot> usb start (Re)start USB... USB: scanning bus for devices... USB device not responding, giving up (status=20) 2 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found
I have tried U-boot version 1.3.4 and see the same issue. I am using U-boot from the linux demo that came with the atmel kit.
Please, move to the latest release (e.g. 2009.03), it has a lot of problems solved with USB and sam926x. (Notice also that the Atmel kit provides bootstrap code with a PLLB configured wrong for sam9263, which is solved in latest U-boot releases as well)
Kind Regards,
Remy
