So we write oob with oobsize aligned (16bytes) instead of 3 bytes (from {2, 3}) Signed-off-by: Kyungmin Park --- diff --git a/drivers/mtd/onenand/onenand_base.c b/drivers/mtd/onenand/onenand_base.c index e342ba04118a..6b950ab8ea8d 100644 --- a/drivers/mtd/onenand/onenand_base.c +++ b/drivers/mtd/onenand/onenand_base.c @@ -965,8 +965,11 @@ static int onenand_write_oob(struct mtd_info *mtd, loff_t to, size_t len, this->command(mtd, ONENAND_CMD_BUFFERRAM, to, mtd->oobsize); - this->write_bufferram(mtd, ONENAND_SPARERAM, ffchars, 0, mtd->oobsize); - this->write_bufferram(mtd, ONENAND_SPARERAM, buf, column, thislen); + /* We send data to spare ram with oobsize + * to prevent byte access */ + memset(this->page_buf, 0xff, mtd->oobsize); + memcpy(this->page_buf + column, buf, thislen); + this->write_bufferram(mtd, ONENAND_SPARERAM, this->page_buf, 0, mtd->oobsize); this->command(mtd, ONENAND_CMD_PROGOOB, to, mtd->oobsize);
