The last image I made worked ok. The difference was that I changed the -c 1996 to -c 4010 in the mkfs.ubifs call. My flash segment has 4011 blocks. 1996 was too few. I think the image was getting truncated. I can't explain why the superblock was coming up empty, but the image is working now. Thanks, Larry
