Hi ,

  thanks Wlofgang Denk for the answer we can use ramdisk image used for other kernel version , 
now i am using ELDK 3.1.1 , and also using the ramdisk image provided by the ELDK ramdisk_image.gz , 
and in kernel i have configured for intial ramdisk support with size 4096 and for ext2 file system , 
it gives the message 

VFS kernel panic unable to mount root fs 01:00 

i tried both options 
first one making a multi image 
using mkimage clubbing it into one image FI64_fresh , with vmlinux.gz and ramdisk_image.gz 

./mkimage -A ppc -O linux -T multi -C gzip -a 0 -e 0 -n FI64_fresh -d vmlinux.gz:ramdisk_image.gz FI64_fresh
  
i download FI64_fresh at 0x500000 using tftpboot 

use bootm 0x500000 to boot the kernel i get the above message .

second option 

at 0x500000 in ram i download uImage of the linux-2.4.25 .
at 0x600000 i download ramdisk_image.gz 

and use the command 
bootm 0x500000 0x600000 
 i get the same message as above 

i do intial check using imi command it says images are fine after veryfing checksum 

is it i am missing somethoing else please let me know or is there any other way to check this 


Thanks In Advance 
Neelu

It certainly gives some more messages, which you did not  share  with
us. Also your kernel configuration is unknown to us.

So what do you expect? That we guess the casue of teh problem from  a
single line of output? I'm afraid it doesn't work like that.

Provide better information, and you might receive better advice.

Best regards,

Wolfgang Denk
