This adds an extra check when data is written to the flash. The
|
|
NAND flash device internally checks only bits transitioning
|
|
from 1 to 0. There is a rare possibility that even though the

|
device thinks the write was successful, a bit could have been
|
|
flipped accidentaly due to device wear or something else.

Enable the use of the S3C2410's internal ECC generator when

(Note that on PowerPC, the normal probe will only check at

0xE4000000.)

bool "Allow BBT writes on DiskOnChip Millennium and 2000TSOP"

depends on MTD_NAND_DISKONCHIP
|
|
help
|
|
On DiskOnChip devices shipped with the INFTL filesystem (Millennium
|
|
and 2000 TSOP/Alon), Linux reserves some space at the end of the
|
|
device for the Bad Block Table (BBT). If you have existing INFTL
|
|
data on your device (created by non-Linux tools such as M-Systems'
|
|
DOS drivers), your data might overlap the area Linux wants to use for
|
|
the BBT. If this is a concern for you, leave this option disabled and
|
|
Linux will not write BBT data into this area.
|
|
The downside of leaving this option disabled is that if bad blocks
|
|
are detected by Linux, they will not be recorded in the BBT, which
|
|
could cause future problems.
|
|
Once you enable this option, new filesystems (INFTL or others, created
|
|
in Linux or other operating systems) will not use the reserved area.
|
|
The only reason not to enable this option is to prevent damage to
|
|
preexisting filesystems.
|
|
Even if you leave this disabled, you can enable BBT writes at module
|
|
load time (assuming you build diskonchip as a module) with the module
|
|
parameter "inftl_bbt_write=1".
