Jason, I was trying to update the uboot for my roach board following the instruction from: http://casper.berkeley.edu/wiki/ROACH_kernel_uboot_update But I cannot interrupt the booting process, it always boots from the USB stick. (I save the bootcmd environment to run usbboot) I tried every key to stop the booting process(ctrl-c, ctrld-d, ctrl-z, space, etc.), no one works. Is there any way I can interrupt the booting process, so I can type the uboot command, following the update procedure. Or is there any way I can clear the uboot environment without booting into the uboot.
