Hello Stelian,
I gave your patches a run on an AT91CAP9 and had limited success with them (usb seems to work, usb storage do not):
Does it work without the patches? Is it a regression, or still an improvement?
U-Boot> usb part print_part of 0
Partition Map for USB device 0 -- Partition Type: DOS
Partition Start Sector Num Sectors Type 1 63 1974208 6
print_part of 1 ## Unknown partition table
These errors are normal, 'usb part' seems to look for primary partitions on a USB stick that is formatted as a floppy...
U-Boot> usb storage Device 0: not available
U-Boot> fatinfo usb 0:1
** Invalid boot device **
I have no explanation for this error, it could be related to the filesystem on the USB stick itself. I do not see any errors that USB itself is not working, the problems I fixed were in the USB area, and they solved all the problems I encountered with USB sticks on AT91SAM9261 (OHCI)
I would expect that it would work much better than before on your CPU... Unfortunately I do not have a test environment for AT91CAP9, so I cannot verify this issue here.
Kind Regards,
Remy
