Re: No console on SMDK2440 Board boot

["Kevin Morfitt" <kevin.morfitt@xxxxxxxxxxxx>]

I removed devfs and now get "VFS: Cannot open root device "mtdblock/2" or 
unknown block(2,0)". I've noticed I haven't got any mtd entries in /dev so 
maybe devfs was handling mtd in the absence of /dev/mtd nodes. I'll add mtd 
nodes to /dev and see what happens.

I'm on 2.6.10 because when I tried 2.6.20.1 I didn't see any boot messages. 
Using GDB I could see it was trying to boot in the background and failed to 
boot but I couldn't see why it failed to boot because of no boot messages. 
If I set the wrong mach type in r1 it did give me a serial port error 
message so the serial port was working. My 2.6.10, supplied by Samsung and 
modified by them to add support for various SMDK2440 devices (which probably 
rely on devfs), at least gives me boot messages so I'm trying to get 2.6.10 
to boot correctly then going back to 2.6.20.1 (or whatever the head is now). 
I'm new to Linux - it's a bit of a challenge isn't it? ;)
