You can't use FIS and linux jffs2 together on one chip. Moreover, eCos doesn't have linux-compatible NAND flash driver. > In this scenario, why redboot don't make access to boot flash ? > Where the Redboot image are stored ? Redboot just runs from boot flash (or loads to ram). In this case you don't need flash driver. > How can update Redboot ? You can't. > There is any board that implement this scenario? e.g. LPC-E2294 (http://sgs.gomel.by/sg/articles/olpce2294/index.html) Alexey -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
