i can run the kernel and ramdisk correct when i embedded ramdisk in
kernel,and i use
bootm can bootm them correctly.
but if i make vmlinux and ramdisk as two image to bootm
it get VFS panic can't find root device
as follow is my use of mkimage
mips_fp_le-objcopy -O binary -R .note -R.comment -S vmlinux linux.bin
gzip -9 linux.bin
./mkimage -A mips -O linux -T kernel -C gzip -a 0x80008000 -e
0x80170040 -n "Linux" -d linux.bin.gz uImage
./mkimage -n 'Simple Initrd Image' -A mips -O linux -T ramdisk -C gzip
-d initrd.bin initrd
and i set bootargs root=/dev/ram0
and load uImage to 0x80600000, ramdisk.gz to 0x80700000
and then bootm 0x80600000 0x80700000
Best regards

Try this:
root=01:00
or
root=0100
(i.e. point major:minor)
