UBIFS ReadOnly FS

We are using iMx6ULL in our design with Toshiba NAND. When run my application more than a day , i m getting below errors,

UBIFS error (ubi0:0 pid 22611): ubifs_scan: corrupt empty space at LEB 1565:81920

I/O error : Read-only file system

May i know what could be the reason for above issue and is there any fix for this?

Note : This application will read sensor data, gps data, CAN data and also file read/write operation to some text file. which is of less size.

When i checked in google, the bit corruption due to other reasons may not be handled properly. So what can be done for this?

Hi Velayutha

seems this is specific ubifs error and was reported many times:

UBIFS corruption bug

ubifs_scan: corrupt empty space

From log L4.1.15 kernel used, so may be recommended to try with latest kernels described on

i.MX Software and Development Tools | NXP
