Am I doing something wrong?

Altera_Forum · ‎12-08-2004

I have a Microtronix uKit development board.

I want to use jffs2 as my root filesystem.

The mtd drivers correctly detect my 8MB flash and set it up with two partitions.

One of them is at offset 0 and is 2MB in size.

The other is at offset 0x200000 and is 6MB in size.

I have used the mkfs.jffs2 tools to create a jffs2.bin of my filesystem.

I have used the upload tool to upload jffs2.bin at offset 0x200000.

The pass the kernel the argument of "root=/dev/mtdblock1".

Is there something else I need to do in order to get this to work.

Right now I'm getting the usual error:

"Kernel panic: VFS: Unable to mount root fs on mtdblock1"

Hmmm ... this sounds familiar -- I had a similar problem before I

switched to cramfs. Unfortunately, I didn't keep good notes :-(

but I believe I had to pass rootfstype=jffs2 as well.

Anyway, there was another cmdline parameter that I needed ... sorry

I can't be more specific ... give the above a try though.

PS -- you also have to make sure your /dev/mtdblock1 inode has

the correct major,minor numbers .
