| + | ===== consistent nand map between kernels ===== | ||
| + | first set the two mtdids/ | ||

| + | set mtdparts mtdparts=orion_nand: | ||
| + | mtdparts add nand0 6M uImage | ||
| + | mtdparts add nand0 - rootfs | ||
| + | </ | ||
| + | |||
| + | That is my nand's layout inside factory firmware. You'll also need to mention $(mtdparts) inside bootargs. | ||
| + | |||
| + | Then I was hoping that using **mtdparts del nand0,0** and removing the uboot partition would suffice on making normal kernels ignore the 4-bit ECC and printing a screen-full of bad block messages upon boot. :\ | ||
