LSDK2108 SPI NOR FLASH JFFS2 initialize rootfs kernel panic

[Hugh512]

rootfs is flashed into SPI NOR flash

1. bootargs

set bootargs console=ttyS0,115200 noinitrd root=/dev/mtdblock4 rootfstype=jffs2 rootwait rw earlycon=uart8250,mmio,0x21c0500 quiet lpj=250000

2. rootfs is generated by

flex-builder -i mkrfs -r yocto:tiny

3. mkfs.jffs2 command

flexbuild_lsdk2108/build/rfs/rootfs_lsdk2108_yocto_tiny_arm64/target

sudo mkfs.jffs2 -o test.jffs2 -r target/ -e 0x10000 -s 0x1000 -n -l --pad=0x1000000

After booting into kernel, kernel crash:
