NAND is not good at handling absolute addresses to sectors for storing particular data. The current implementation of the NAND env support works around this in several ways such as storing a pointer to the sector in the OOB of the first sector (interferes with some CRC) or supporting a range of sectors (which unless it is huge is not guaranteed to be safe). None of these options address wear-leveling concerns or bad block handling.
Accessing the u-boot env from UBI eliminates these concerns. However, it does require some of the basic settings for finding the UBI env to be in the default u-boot env.
One question: Do you plan to support the fw_env Linux tools with this env-in-UBI feature as well?
Thanks, Stefan
