2014-06-25nanddump: change default to --bb=skipbadRichard Genoud
since mtd-utils 1.4.7, the default behaviour of nanddump is skipbad (commit 2521d4f1b6b9866a9c89f3c11a4f6a3d763ff1d7) Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2014-06-25nanddump: add options --bb=skipbad and padbadRichard Genoud
In mtd-utils, the bad block options changed in favor of --bb=[skipbad|padbad|dumpbad] and omitbad has been removed. This patch add the --bb=skipbad and padbad methods to busybox' nanddump. padbad is the current default behaviour. The difference between skipbad and omitbad is this one: On a 16K block NAND, if the 1st block of mtd0 is bad, we'll have: nanddump -b -l 16384 /dev/mtd0 | wc -c 0 nanddump --bb=skipbad -l 16384 /dev/mtd0 | wc -c 16384 <- data from 1st good block Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2014-06-25nanddump: correct rounding to next page (lead to infinite loop)Richard Genoud
The rounding to next page formula was wrong: ex: (len | ~(meminfo->writesize - 1)) + 1; len=128K writesize=4K (len | ~(meminfo->writesize - 1)) + 1 => 4 294 963 201 ?! correct rounding formula: ((len - 1) | (meminfo->writesize - 1)) + 1 => 128K len = 130K ((len - 1) | (meminfo->writesize - 1)) + 1 => 132K modprobe nandsim parts="20,20" badblocks="22,23" without patch: nanddump /dev/mtd1 | wc -c [...] infinite loop with the patch: nanddump /dev/mtd1 | wc -c 327680 Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
