Please keep replies on the eCos list so that all may benefit.

AFAIK, that port only supports the NOR FLASH on the board.  If you want
to add NAND, you'll need to write the drivers, etc, yourself.  There
has been much discussion on this topic of late; check the archives.

Hi all,

I have a freescale based development board. I am trying to boot from
nand using redboot. My queries are:

1. How would I enable the nand flash in redboot?
2. How to integrate jffs2 filesystem with redboot?
3. If integrated will I be able to write, read, erase files in the nand
flash?
4. How could I enable the support for these functionalities?

What kind of Freescale development board is it?
Where did you get the RedBoot/eCos sources (if not from the public CVS
tree)?
