+          devices. For further information see

+          This adds an extra check when data is written to the flash. The
+          OneNAND 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.
