Hi all, i'm quite new to this material, so if you see that I understood something wrong - please inform me about. I got a tiny6410 SDK Kit and want to play around with it. Currently there is QTopia installed on it and everything is fine. As I do not have much experience, I wish to do a NAND Backup to be able to restore simply everything if I crash something. What I did till yet: - Flashing SD Card with superboot6410 - added images/FriendlyARM.ini - added images/Android/rootfs, android images, superboot - changed FriendlyARM.ini to not automatically run/install - Starting and connecting DNW per Serial and USB to the kit - starting the kit with SD Boot -> in DNW 0.5A: - USB > Status - USB Backup NAND Flash to file - Selecting File and from here on - sometimes I get an USB Failed err:284 error, sometimes a Progressbar comes - but never proceeds. My question: How did you do the backup? Am I missing something? I'd really appreciate your help bye yours sincerly Thomas
