mtd: nand: fix bug writing 1 byte less than page size 2016-07-25T01:36:29+00:00 Hector Palacios hector.palacios@digi.com 2016-07-18T07:37:41+00:00 ebb7febc92fc628d1f37b96616a1bb21b646d072 nand_do_write_ops() determines if it is writing a partial page with the formula: part_pagewr = (column || writelen < (mtd->writesize - 1)) When 'writelen' is exactly 1 byte less than the NAND page size the formula equates to zero, so the code doesn't process it as a partial write, although it should. As a consequence the function remains in the while(1) loop with 'writelen' becoming 0xffffffff and iterating until the watchdog timeout triggers.

equates to zero, so the code doesn't process it as a partial write, although
it should.
