More testing....
It seems like I have one stick that generates the reported error. And this is of course THE one I have been testing with (Murphy is never resting...)
I have tried with four devices now USB 1.0 128MB : Had to repartition USB 2.0 512MB : Gives the reported problems (fine in linux and windows) USB 2.0 2GB : Works without partitioning USB 2.0 16GB: Works without partitioning
The response is the same on our own at91sam9263 board with 18.432MHz ocillator and the original at91sam9263ek with 16.36766MHz
So - I'm willing to rest my case :-) BUT there is something strange, since the "bad" stick works fine in Linux and Windows... -Any ideas about possible reasons for the difference? -Is there any specific known requirements for the sticks (except for FAT)
Best regards Pål Bakken

I have testet a lot more and have found the following:
I tried an old USB 1.0 stick, but got the same bad result...
Then I took that USB 1.0 stick and deleted multiple partitions with linux fdisk and created a single bootable FAT32 partition. This variant worked without any problems in u-boot. (the multiple partitions seems to be typical from the vendors)
Then I took the USB 2.0 stick (from the trace in my first mail) and did the same repartioning with fdisk. But this stick still gives the same bad result :-(
So????
Are there any known limitations/requirements to the u-boot USB implementation? -USB1.0 vs USB2.0 -How to partition the stick (if the original partition can't be used) -Other
...and once more: the USB 2.0 stick works fine in linux....
I'll take a look on my 9263ek
but I've test recently a 4GB usb 2.0 key on the at91rm9200ek with any problem
btw please limit your mail at 80chars per line
