NAND Writing

WARNING: The content of this section is considered DEPRECATED and OBSOLETE It is preserved for historical or documenting reasons. Some recipes for putting filesystems onto NAND FLASH. See also Installing_to_NAND. Bad Block Table Messed Up This is a recipe for erasing the NAND Flash and rewriting it, in the event that the bad block table is potentially messed up. Boot from a USB key, passing the cmdline argument "cafe_nand.skipbbt=1" Login as root modprobe mtdchar flash_eraseall -j /dev/mtd0 nandwrite -p /dev/mtd0 build131.img Reboot, and the BBT should be recreated as cafe_nand loads, based on the bad blocks found during formatting. Copying Stuff on as Files This is for when you don't have a preformatted JFFS2 image and you just want to make an empty filesystem and copy on some files. modprobe mtdchar flash_eraseall -j /dev/mtd0 mount -tjffs2 mtd0 /mnt # Now use cp, or tar, or whatever to copy files into /mnt umount /mnt Note that the "umount" command will sometimes take a while to finish.
