Yeah, I looked at that, but also wanted to cater for Phase1 developers (and some Phase0 developers) who don't have a debug board. >> 2) The only way I can find to get out of uboot DFU Mode back to uboot >> Runtime Mode is to do a dummy download (e.g. download a file to RAM) >> which puts uboot back into Runtime Mode (from which you can reset or boot). > > Is dfu-util -R not working for you ?

I'd also love a way for dfu-util to completely power-cycle the neo remotely :-) >> It would be good to have a dfu-util option which just resets back to >> runtime mode without having to do a scary dummy download. > > As far as dummy downloads are concerned, -a 0 isn't so scary :) True. -- Rod
