imx6 ubifs sqnum error

[XiaofengZang]

Hello

imx6 linux ubifs system found sqnum error after using 3 months, the rootfs is read only.

log is in attachment,why bad replay sqnum is smaller than commit sqnum?

it should be bigger than commit forever

Hi Xiaofeng

one can try with latest nxp linux releases from Code Aurora git repositories  repository

linux-imx - i.MX Linux kernel 

Documentation i.MX Software | NXP 

also (to exclude quality issue) one can try with other nand part form another vendor.

Best regards
igor

Hi

this reason is nand driver update, our version is 4.1.15, it's too old.

你好，我们这边也遇到相同的问题，请教一下你那边驱动升级了哪些文件。能打个压缩包，我们这边参考一下吗？
