New Revision: 1603
URL: http://svn.slimdevices.com?rev=1603&root=Jive&view=rev
Log:
Bug: N/A
Description:
Added new commands to the bootloader for verification of bad blocks.
nandbb <block> <numblocks> # prints out any blocks with bad block mark
nandmb <block> # marks the block as a bad block
nande <block> <bytes> # not new, but can be used to remove a bad block mark
For example:
JIVE# nandbb 80 580
StartBlock 128 (0x80) : NumBlock 1408 (0x580)
[block 804 (0x324) has been marked as a bad block(0)]
JIVE# nandmb 322
Mark block 802 (0x322) as BAD
[block 802 (0x322) is marked as a bad block]
[block 802 (0x322) has been marked as a bad block(44)]
JIVE# nandbb 80 580
StartBlock 128 (0x80) : NumBlock 1408 (0x580)
[block 802 (0x322) has been marked as a bad block(44)]
[block 804 (0x324) has been marked as a bad block(0)]
JIVE# nande 322 4096
StartBlock 802 (0x322) : Size 16534 (0x4096)
Total Erase Blocks 1 (0x1)
JIVE# nandbb 80 580
StartBlock 128 (0x80) : NumBlock 1408 (0x580)
[block 804 (0x324) has been marked as a bad block(0)]
