Jffs support into kernel?
« on: January 17, 2004, 02:36:54 pm »
Hi there!

I want to have jffs2 support in my kernel in order to be able to customize my OZ Rom-Image. How do I get it? Now, I have a self-configured kernel, but the option for jffs2 is greyed out in xconfig and not appearing in menuconfig. I guess there\'s some sort of dependency that I have to enable something else in the kernel, but the docs aren\'t giving anything away... Btw, it\'s a 2.4.22 kernel, patched to 2.4.23-pre4.

I\'d be really grateful for any hint, cheers

You need to enable Memory Technology Devices (MTD) support. It has it\'s own section on the main menu.

Are you sure you don\'t already have it. My Mandrake ROM came with it.

modprobe mtdblock
modprobe mtdram -o total_size=16384
modprobe jffs2
dd if=initrd.bin of=/dev/mtdblock/0
mount -t jffs2 /dev/mtdblock/0 mnt/initrd

Or something similar.

Nope, tumnus is right  My kernel is self-compiled, so the probability\'s very high that I missed something there.... thanks anyway, both of you
