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 > From: Jean-Christophe PLAGNIOL-VILLARD [plagn...@jcrosoft.com] > Sent: 2009-01-14 22:24:22 CET > To: Paal Bakken [pabak...@online.no] > Cc: Remy Bohmer [li...@bohmer.net], u-boot@lists.denx.de > Subject: Re: [U-Boot] Problems with USB mass storage on at91sam9263 > > On 22:30 Wed 14 Jan , Paal Bakken wrote: > > I have testet a lot more and have found the following: > > > > 1.
