We want to have jffs2 running on a part (some megabytes / one FIS partition) of the NAND flash, to store configuration and theming data. I'm currently reading the sources, and it seems ugly, but doable. Ugly, because it looks like the flash driver interface consists of some static functions, so it will be impossible to support different flashes concurrently. Luckily, we'll only need a single flash unit at the moment. Thanks for your answer, Markus -- Markus Schaber | Logical Tracking&Tracing International AG Dipl.
