[U-Boot-Users] U-boot+Arm linux 2.4.19-rmk7 boot problem

[Annamalai Prakash]

Hai Guys,

        I find the Kernel Entry Address and Load address for ARM kernel.
it is 0x8000. Now my system hangs after "Kernel panic: VFS: Unable to
mount root fs on 01:00". The kernel has Ramdisk support,ext2 file system
support.I dont know where i m doing mistake.
