help

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 accidentally due to device wear or something else.
