Hi Yifan, This sounds like the missing mmc drivers that was fixed in the latest kernel release. You can update your kernel to the newest one found here:
https://casper.berkeley.edu/wiki/LatestVersions using the instructions here: https://casper.berkeley.edu/wiki/ROACH_kernel_uboot_update I can help you with that if you'd like. Dave/Alec: As an aside, has Mo's setup been updated with the newest kernel you compiled in August? Yifan's board was done in late June, so it would have had the May release of the kernel.

Hi, I am a new ROACH user and I am having some difficulty setting things up. Currently, I'm trying to set up netboot so I can ssh bof files to the board, but somehow in the process of things I seem to have messed up the boot partitions. So now I get an error every time I boot using mmcboot, usbboot, basically in any way other than soloboot: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1) Rebooting in 180 seconds.. Is there a way to recover the original settings? I've tried rebooting, but otherwise I'm not sure how to fix this bug. Should I just remount the image somehow onto a USB drive? Any advice would be appreciated. I am new to this mailing list so if there is a more appropriate place to direct these questions please let me know, Thanks, Yifan
