Hello All,

Does ECOS has a FTL(Flash Translation Layer) module to emulate a
NOR/NAND flash as a block device?

Sort of. See packages/io/flash/current/src/flashiodev.c. NOR only.

NAND flash is so prevalent!
Will ECOS support NAND flash later?

Some NAND flashes are supported, but at the moment this is no central
support.

It needs somebody to write the necessary code for all the checksum and
block management, preferably in a way which is compatible with Linux.

Feel free to submit a patch...
