Please try:
- Modify m25p80.c files instead of dev.c file Path: output/build/linux-master/drivers/mtd/devices/m25p80.c
/ { "w25q256", INFO(0xef4019, 0, 64 1024, 512, SECT_4K) }, / { "w25q256", INFO(0xef4019, 0, 64 1024, 512, 0) },
-
Use mkfs tool to generate rootfs ~Buildroot/output/images$ sudo mkfs.jffs2 -s 0x1000 -e 0x10000 -p 0x800000 -d ./rootfs -o jffs2.img
-
Modify Auto Mount Path: board/nuvoton/rootfs-xxx/etc/mdev.conf
mtdblock([3-9]+) 0:0 660 */sbin/automount.sh $MDEV X${ACTION}
Hi Nuvoton,

It works like below.

I didn't know, so I modified spi0 spi1 to be the same.
