Hi: York
1, There is an issue for sdk2.0 kernel that the nor-flash can't be probed . we
can fix it as follow:
$make menuconfig
x -> Device Drivers
x -> Memory Technology Device (MTD) support
x -> RAM/ROM/Flash chip drivers
x -> Flash chip driver advanced configuration options
x -> Flash cmd/query data swapping
x x ( ) NO
x x (X) BIG_ENDIAN_BYTE
x x ( ) LITTLE_ENDIAN_BYTE
Enable BIG_ENDIAN_BYTE .
2, The spi-nor flash can working on ls1043aqds , and I use the sdk2.0 kernel
(ce5a3841f3).
[ 1.598954] m25p80 spi0.0: n25q128a11 (16384 Kbytes)
