Hi,
following the instructions on the wiki about UBIFS, I am root mounting a UBIFS filesystem, but am running into problem, when the filesystem switches into read-only mode. The filesystem was created per instructions and is flashed with BCH8 at 0x6c0000 offset, i.e. mtd7.

There are some issues with bad PEB handling and not enough reserved space. Could you guide me in the right direction on what needs to be changed?
Thanks,
