STM32MP157 NAND FLASH error

[Yli.8]

​We used nandflash of MT29F4g08ABADAWP and found that there was an error in startup. May I ask how to solve it?

Boot over nand0!

ubi0: attaching mtd4

ubi0: scanning is finished

ubi0: volume 3 ("userfs") re-sized from 521 to 587 LEBs

ubi0: attached mtd4 (name "UBI", size 506 MiB)

ubi0: PEB size: 131072 bytes (128 KiB), LEB size: 126976 bytes

ubi0: min./max. I/O unit sizes: 2048/2048, sub-page size 2048

ubi0: VID header offset: 2048 (aligned 2048), data offset: 4096

ubi0: good PEBs: 4044, bad PEBs: 4, corrupted PEBs: 0

ubi0: user volume: 4, internal volumes: 1, max. volumes count: 128

ubi0: max/mean erase counter: 1/0, WL threshold: 4096, image sequence number: 826760955

ubi0: available PEBs: 0, total reserved PEBs: 4044, PEBs reserved for bad PEB handling: 76

UBIFS error (ubi0:0 pid 0): ubifs_recover_master_node: failed to recover master node

Error reading superblock on volume 'ubi0:boot' errno=-22!

ubifsmount - mount UBIFS volume

Usage:

ubifsmount <volume-name>

   - mount 'volume-name' volume

Hi @昌�?� �?�​ 

Can you please share more detail when you get this message ?

Is it during flash procedure or when booting once flashed ?

Can you share the .tsv file you are using ?

Thanks,

Olivier
