Hi,
I want to use nand ubifs as rootfs, and the MTD driver was built in linux kernel, but can't mount the ubifs when booting, and MTD was not loaded at that time.
There's an error printed by kernal when booting:
UBI error: cannot open mtd rootfs, error -2console [netcon0] enabled
uboot cmdline:
nandboot=setenv bootargs console=ttyS1,115200n8 rootwait=1 rw ubi.mtd=1,2048 rootfstype=ubifs root=ubi0:rootfs
How to load MTD before the ubifs is loaded?
Other Info：
dmesg(with emmc boot, you can see mtd was loaded at filesystem-stage after kernel-stage):
