I still can't boot 11.3.0 from USB following http://wiki.laptop.org/go/OS_images_for_USB_disks#Booting. James Cameron helpfully replied: > I would use http://wiki.laptop.org/go/Tiny_Core_Linux to boot from USB > and investigate the cause: That worked using boot u:\boot\olpc.fth , very nice! I tweaked your F.S. test steps to: # cat /proc/mtd # mkdir /mnt/MY_XO_FS # mount -t jffs2 mtd0 /mnt/MY_XO_FS (I updated the wiki page with all this) at which point after about 15 seconds I get JFFS2 error: (1053) jffs2_build_inode_pass1: child dir "root" (ino #340448) of dir ino #340447 appears to be a hard link Yet the NAND flash contents look pretty good, /home/olpc, /versions, etc. `find -inum 340xxx` fails to find those inode numbers, but prints find: ./versions/run/af5b6blahblah: Input/output error `ls` reports this directory doesn't exist. Unfortunately there's no fsck.jffs2 , so this seems irreparable. I hope it's just hardware rather than the "steps to free up disk space" that I vaguely recall running before I last shut down. > I would also make a backup using the xo-backup tool included on the Tiny > Core Linux build modified for XO-1. That worked, nice! % gtar -v --create --directory /mnt/MY_XO_FS/home/olpc \ --file /mnt/sda1/xo_home_olpc.tar . Thanks again! Now I'll install *without* using olpc-update for the first time in years. -- =S Page _______________________________________________ Testing mailing list [email protected] http://lists.laptop.org/listinfo/testing
