This caused ECC calculation to fail for odd bytes Signed-off-by: Chad Monroe Signed-off-by: Felix Fietkau --- diff --git a/target/linux/ramips/patches-5.10/410-mtd-rawnand-add-driver-support-for-MT7621-nand-flash.patch b/target/linux/ramips/patches-5.10/410-mtd-rawnand-add-driver-support-for-MT7621-nand-flash.patch index 8049dbde14..3314013420 100644 --- a/target/linux/ramips/patches-5.10/410-mtd-rawnand-add-driver-support-for-MT7621-nand-flash.patch +++ b/target/linux/ramips/patches-5.10/410-mtd-rawnand-add-driver-support-for-MT7621-nand-flash.patch @@ -233,7 +233,7 @@ Signed-off-by: Weijie Gao +#define DEC_EL_EVEN_S 0 +#define DEC_EL_M 0x1fff +#define DEC_EL_BYTE_POS_S 3 -+#define DEC_EL_BIT_POS_M GENMASK(3, 0) ++#define DEC_EL_BIT_POS_M GENMASK(2, 0) + +#define ECC_FDMADDR 0x13c +
