Hi, Wanted to try a new uboot on my guruplug server with openocd 0.9.0-1+b1 and my SheevaPlug JTAGKey FT2232D device. I got very similar bug. I've modified the /usr/share/openocd/scripts/interface/ftdi/sheevaplug.cfg file to use ftdi_channel 0 and not 1. With that change, I was able to use openocd, keep the serial console open and flash a new uboot.
I guess it would be interesting that others people having the problem confirm it's working for them too. Arnaud
