Suggest you trying fsck in Linux PC first.

Also are you using VFAT sytsem?

> Hello, Our SD card in a mangoh red gets corrupted from time to time. We would like to run fsck, but the system reports that fsck.vfat is missing. Since fsck is within busybox, I guess that we need to update busybox by updating yocto?? Any idea? Thanks
