Restoring the NAND Flash
Additional Procedures A-15
7) Execute the following commands to mount the MMC/SD and NAND
partitions and populate the YAFFS2 image:
EVM # mkdir /mnt/mmc
EVM # mkdir /mnt/nand
EVM # mount -t vfat /dev/mmcblk0 /mnt/mmc/
EVM # flash_eraseall /dev/mtd0
EVM # mount -t yaffs2 /dev/mtdblock0 /mnt/nand/
EVM # cd /mnt/nand
EVM # tar xf /mnt/mmc/dm357_flash_image_#_#_#_#.tar
EVM # cd
EVM # umount /mnt/nand
EVM # reboot
The first mount command assumes you have a VFAT partition. The
tar command will take about a minute to run.
The filename of the dm357_flash_image_#_#_#_#.tar image will be
in DOS 8.3 format if you are using a vfat filesystem. That is,
dm357_fl.tar.
8) When the EVM comes up after rebooting from the previous steps,
press Esc to get back to U-Boot prompt. You can now restore the out-
of-the-box U-Boot environment variables as described in Section
A.4.1.
