can not mount UBIFS file system with devicetree
lampl92 opened this issue · 1 comments
File system can not mount when use UBIFS file system on NK-980IOT-V1.0
i also attach buildroot, uboot, kernel, device tree, ubinize config, could you please help me to figure out?
Check ubi partition in uboot
=> mtdparts
device nand0 , # parts = 4
#: name size offset mask_flags
0: u-boot 0x00200000 0x00000000 0
1: kernel 0x00700000 0x00200000 0
2: device-tree 0x00100000 0x00900000 0
3: rootfs 0x07000000 0x01000000 0
active partition: nand0,0 - (u-boot) 0x00200000 @ 0x00000000
defaults:
mtdids : nand0=nand0
mtdparts: mtdparts=nand0:0x200000@0x0(u-boot),0x1400000@0x200000(kernel),-(user)
=> ubi part user
incorrect device type in user
Partition user not found!
=> ubi part rootfs
