--- Booting from JFFS2 root ---
|
||||
|
||||
1. First boot the board with NFS root.
|
||||
|
||||
2. Erase the MTD partition which will be used as root:
|
||||
|
||||
$ flash_eraseall /dev/mtd3
|
||||
|
||||
3. Copy the JFFS2 image to the MTD partition:
|
||||
|
||||
$ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3
|
||||
|
||||
4. Then reboot the board and set up the environment in U-Boot:
|
||||
|
||||
=> setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
