As the READID function did not propagate the second id parameter but had a hard-coded call for 0x90 0x00, reading the ONFI identifier was not possible and thus chips werde not detected (tested with MT29F8G08ABABAWP) Signed-off-by: Enrico Jorns Signed-off-by: Brian Norris --- diff --git a/drivers/mtd/nand/denali.c b/drivers/mtd/nand/denali.c index 870c7fc0f759..7b6186ffe3ac 100644 --- a/drivers/mtd/nand/denali.c +++ b/drivers/mtd/nand/denali.c @@ -1304,7 +1304,7 @@ static void denali_cmdfunc(struct mtd_info *mtd, unsigned int cmd, int col, */ addr = MODE_11 | BANK(denali->flash_bank); index_addr(denali, addr | 0, 0x90); - index_addr(denali, addr | 1, 0); + index_addr(denali, addr | 1, col); for (i = 0; i < 8; i++) { index_addr_read_data(denali, addr | 2, &id); write_byte_to_buf(denali, id);
