Hi everyone,
I want to use ramdisk to boot my filesystem, as I can't use NFS and harddisk.
I have load the ramdisk into the ram memory (start address :0x4000000)
and in the boot options I specified : root =dev/ram0 initrd=0x4000000
but the kernel said it can not find any file system on it.
Here is the information I can supply : U-Boot 1.2.0 (Aug 31 2007 - 20:54:55)
*** Auto-detects ethernet chip ***
DRAM: 0 kB ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB Flash: 0 kB *** Warning - bad CRC, using default environment

Who can give me some hints ? or point me some direction to handle this.
I appreciate this very much.
