trying to boot linux2.6.12 with u-boot-1.1.3 on a ARM versatile board I am facing a difficulty .
the kernel fails at init because i think of my ability to indicate the place where it can find the root file system.
what is to be put in the bootargs?
 
the error message is :
Root-NFS : no NFS server available.
 
please append a correct "root=" boot option
Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(2,0)
 
I have tried many commands all leading to the same error.
 
-setenv bootargs "root=/dev/mtdblock0 mem=128M ether=27,0,0xfc800000,0xfc800010,eth0 mtdparts=versatile:0x5c0000 at 0x1c0000(cram
fs) video=vc:1-2clcdfb:"
 
-setenv bootargs "setenv bootargs root=/dev/mtdblock0 mtdparts=armflash.0:0x65d000 at 0x2200000(cramfs) ip=none mem=128 console=ttyAMA0 video=vc:1-2clcdfb:"
 
my cramfs is in flash at address 0x341c0000 while the basis of my flash memory is 0x34000000.
 
Anyone ?
greetings 
thomas

The correct root device, of course.

And what was the other boot messages?

Did the boot messages indcate that the kernel really created  a  MTD0
device  as per your request? Did you enable command line partitioning
in your kernel configuration? Did you enable cramfs support  in  your
kernel configuration?

This is  obviously  wrong  but  the  kernel  will  ignore  the  bogus
additional arguments "setenv" and "bootargs".

And does your kernel acknowledge this?

[BTW: this has nothing to do with U-Boot and it off topic at least on
this list.]

Aaarrgh! The same message on three lists and no-one complains?  Has 
everyone gone soft?
