Yeah, but I'm trying to make do without building my own kernels if possible. And yes, the ubiformat "bad eraseblocks" message was indeed a misunderstanding from my part. There was one more error (for benefit of anyone else hitting the same problem): mkfs.ubifs -e 129024 parameter from http://www.plugcomputer.org/plugwiki/index.php/Enabling_UBIFS#Make_ubi_image_out_of_the_ubifs didn't work for me (got "validate_sb: LEB size mismatch: 129024 in superblock, 126976 real"). Fixing this to the number indicated in the error message (126976) fixed it. Looks like I have ubifs working now. :) -- To UNSUBSCRIBE, email to debian-arm-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
