Hi Kshitij,

I am trying to boot the linux kernel with ramdisk support.

The details of the ramdisk image are Image Name: RAm Disk Created: Wed Sep 24 11:55:02 2003 Image Type: ARM Linux RAMDisk Image (gzip compressed) Data Size: 3038830 Bytes = 2967.61 kB = 2.90 MB Load Address: 0x10800000 Entry Point: 0x10800000

The kernel is Image Name: Linux Kernel Image Created: Wed Sep 24 11:56:19 2003 Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 686909 Bytes = 670.81 kB = 0.66 MB Load Address: 0x10C08000 Entry Point: 0x10C08000

The bootargs : setenv bootargs console=ttyS0,115200n8 initrd=0x10800000,8M root=/dev/ram ip=off

If you use U-Boot (at least on PowerPC) you do _not_ need an "initrd" argument, the RAM disk address is passed by U-Boot for you if a second parameter to bootm appears.

The kernel is compiled with ramdisk support. I store my kernel in the flash at location 0x100000 and I download the ramdisk in the ram at location 0x10000000 ( this is starting of my RAM). Now when I boot the kernel with the

$ bootm 0x100000 0x10000000

You are aware that U-Boot takes its input in hexadecimal per default, so this should rather be "bootm 100000 10000000". But as a kernel is started this might be a copy and paste problem.

I get the following error

RAMDISK: Couldn'find valid RAM disk image starting at 0.

Address 0 - looks bogus.

Freeing initrd memory: 8192K cramfs: wrong magic Kernel panic: Unable to mount root fs on 01:00

Am I missing some thing in my steps ?? Any comments will be greatly appreciated.

It would help a lot if you could provide us with a complete transcript of the failing attempt.

Cheers Detlev
