probe of omap2-nand failed with -16

probe of omap2-nand failed with -16

[Pablo Bitton]

Hi,

I've started working on beagle board.

Using pre-compiled kernel (angstrom) - i've got nand driver loaded and running.

When I am trying to compile my own kernel from the source, I get error:

>> probe of omap2-nand failed with -16 (EBUSY)

I've selected all configs for Nand...

Am I missing something? Mux configuration? GPIO's?
Anybody has any idea?



thanks,

This happens because we moved 'gpmc_cs_request' from nand driver
(nand/omap2.c) probe to 'mach-omap2/gpmc-nand.c'.

Yes. You need to adopt gpmc-nand.c for beagle boards.
