Emmc mount fail

Hi

We are using jetson xavier nx and storage is only eMMC.

Under what circumstances does this error occur?

And how can i fix it?

The superblock is corrupt. That’s kind of a master listing of content (notes). That’s pretty bad, and you probably can’t save it (if you can, it will be pieces, and the process best performed on a Linux PC with plenty of disk space).

It could be hardware failure, but that’s unlikely. Things like improper shutdown (including power loss) would typically cause something like this. I don’t see this as “disk full”, I see this as “the data is so corrupt it isn’t known how to fix it”. Has this unit been shut down with proper software commands?

Incidentally, here is some background:

Now that I think about it, it seems that sometimes I turn off the module with a simple power shutdown rather than a software command.

So if this is the case, is it possible to fix it by flashing again?

Flashing will install everything new again. It will work, but it will lose any prior changes.
