I see these tests but I'm not sure how they're used. is their a doc for these?
I'm on a sam9263 platform and I'm sure my timing are within spec.
Infact I stretched
my to be sure it's not timing related. When it works I can see the
files from my bootloader.
Also when it doesn't work, I can still see file fragments.
I briefly tried creating and mounting a ubi volume which worked until
I repeated it with a file
loaded. I get some uncorrectable errors but since I'm not familiar
with this fs and never
used this filesystem before, this could very well be user error.
Thanks.
