Subject: [PATCH 44/71] cmd: mtd: add markbad subcommand for NMBM testing
|
|
|
|
This patch adds:
|
|
* Mark bad block on lower mtd device and erase on upper mtd
|
|
device, which will trigger remapping:
|
|
$ mtd markbad spi-nand0 0x20000 (mark block1 as bad)
|
|
$ mtd erase nmbm0 0x20000 0x20000 (let nmbm detect the bad block and remap it)
|
|
|
|
* Clear bad block mark through:
|
|
$ mtd erase.dontskipbad spi-nand0 0x20000 0x20000
|
|
(After cleaning bad block mark, we need to rebuild nmbm manage table.)
