Probably, u-boot resets it after transfer (have not checked this yet). The idea of bd_t support looks promising anyway, especially if we'll continue our expansion in the embedded world (almost all powerpc and arm embedded boards are moving toward using u-boot exclusively). This way we'll get a good cooperation with another projects. I'll look into this after I get ate0 and usb working. BTW, what is the status of usb for now? Should it work? I'm receiving a 'device problem (IOERROR), disabling port 1' message if device attached. Is it known problem, or something is misconfigured in my board? Thanks for information! -- Stanislav Sedov ST4096-RIPE
