Compiling MTD in the kernel

Hi,

I just tried to compile MTD in the kernel (not as a module) btu, even if everything compiles fine, it doesn't work. If I try to cat a jffs image in /dev/mtd0 (I use mtdram), I get:

bash: /dev/mtd0: No such device.

If I try to mount a partition using jffs (even though this partition isn't jffs), I get:
mount: fs type jffs not supported by kernel

It's the same errors I would get If I had compiled everything as modules but didn't load them.

Any clue?

2.2 kernel, I assume. Did you apply the mtd-patch-2.2.16 from the patches/ directory? It puts all the calls to the init routines in the right place.

I assume you did enable CONFIG_MTDCHAR and CONFIG_JFFS_FS :)

You probably did not patch init/main.c and fs/filesystems.c to call init_mtd() and init_jffs_fs() correspondingly.

Should be there.
