Hi,
I'm trying to boot linux from flash with cramfs from a specific mtd partition. Using fixed maps from /drivers/mtd/maps I had success but with command line arguments I didn't.
I always get the following message:
VFS: Cannot open root device "mtdblock4" or 1f:04 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 1f:04
Does anybody know the right bootargs command line and/or root= parameter should I use?
BTW, I'm using ELDK 3.1 with kernel 2.4.25.
Thx, TT
