Hello!!
A little bit off-topic question: I encountered an issue due to a patch causing
issues on ramips:
<commit>
... so my Zbtlink ZBT-WG3526 (32M) behaved like SPI flash was damaged. After
reverting the patch, anything was OK and the device is still running fine.
So, my question is: are there chances of damaing the flash chip when running on
those situations where bugs happen?
and, what if things like those would happen in NAND flash devices? What if, for
example, we mark as bad a block that wasn't bad after all?
thanks!!
Enrico

Hi Michal
I'm not that deep into the mtd-concat hack (expecially on NAND
flash). We might also run into issues when migrating to the new NAND
interface. If you you've found a fix for this, it would be great to
have it up for discussion on ML or GitHub. Especially as this is more
or less target independant and not directly associated with the ath79
driver.
Best wishes

Hello David,
Yes, I'm going to have a deeper look at mtdconcat driver and try to
modify its behaviour to be consistent with what is now required by
mtdcore. Concat is a virtual device, address translation layer mainly,
so understanding how it works should not require any deep flash hacking
knowledge.
Cheers
Michal
