yes, in following directions for the uboot environment I also told pogo to "uboot_install dockstar"
This command gave me the same "existing firmware cannot be identified" and along with that something along the lines of "...therefore new uboot environment cannot be installed..."
I just plugged along from there. It was interesting, that after entering into the "original" pogoplug OS that the root was pogoplug /$: or something similar, while before updating mtd0 my root was bash 3.2/. Is this because I flashed a new uboot loader (doozan's excellent creation)?
would you suggest I back out of my working server (that upon reboot still presents with the message "...broken pipe...") and make sure that the uboot environment is solid?
