Hello,

We have a Micron 4K page sized ONFI NAND MT29F16G08
I am encountering frequent errors while reading the device. Although the data area is protected for 8bit correction with BCH8 algorithm, the oob area is unprotected and is susceptible to bit flips

These errors are very frequent and it results in jffs2 file system mounting problems and other related issues

I also confirmed the problem through oobtest module.

Can you please suggest any solutions/workaround

Regards
Vipin

Use ubi -- the OOB will then only be used for ECC.
