I think we should change this a little bit. Unluckily I don't know what is the best way to fix it. As far as I have understood, the NAND_NO_SUBPAGE_WRITE is a chip option, not for a driver.
At nand_base.c is chip->options &= ~NAND_CHIPOPTIONS_MSK; chip->options |= type->options & NAND_CHIPOPTIONS_MSK; so the bit is masked out anyway and subpages are enabled.
After that UBI tries to read VID header at 512 by default. I had to use "ubi part root 2048" to override it. Besides of that driver seems to work fine.
Can you please supply me with the commands that trigger such bug and the resulting problem you then see? So I can reproduce it and fix it? Thanks!
