HOWTO load and run the kernel image using redboot?

Hi,
I have compiled the mips kernel image, and got vmlinux. And
how can load image into the ram run using redboot, my board is running with the redboot.
I followed the steps, after i got the vmlinux

1. mips-linux-objcopy -O binary -g vmlinux vmlinux.bin
2. gzip vmlinux.bin
3. mips-linux-objdump -f vmlinux | grep start
shows the entry point, which is say ENTRY
4. mips-linux-nm vmlinux | grep _ftext
which is say MEMADDR.
5. Load the image into memory
At a RedBoot prompt, type:
load -r -b %{FREEMEMLO} vmlinux.bin.gz
6. Copy the compressed image from memory to flash
fis create -e ENTRY -r MEMADDR vmlinux.bin.gz
and once i do go/exec, garbage is showing at the Redboot> prompt...

Can help the way of loading the kernel image using redboot and boot it.
