Get error -74 (ECC error) during ubiattach

[t kevin]

Hi Tanya,

Thanks for the suggestion.
I create the UBIFS by ubiformat+ubimkvol. It was fine at the very
beginning and that error message pops out after a few erase cycles (<
10).
I'm wondering what can I do to fix the problem instead of erase
everything to make it go away.

Thanks
Kevin
