After a bit of investigation it seems like there are two overlapping bugs in the original framework that cause silent failure when writing a bad block marker. This set contains fixes for both of these issues and one more fix (patch 2) that should not affect the actual behavior of the driver. Frieder Schrempf (3): mtd: spinand: Stop using spinand->oobbuf for buffering bad block markers mtd: spinand: Explicitly use MTD_OPS_RAW to write the bad block marker to OOB mtd: spinand: Wait for the erase op to finish before writing a bad block marker drivers/mtd/nand/spi/core.c | 67 +++++++++++++++++++------------------ 1 file changed, 34 insertions(+), 33 deletions(-) -- 2.17.1 ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
