Those instructions are useful, but since I am not a MIPS developer I don't have an existing toolchain/kernel tree and rootfs available to test this. If you can provide me with a link to your vmlinux and rootfs with busybox or similar in it, I can take a look to see what is happening here. Otherwise it's almost impossible for me to understand and debug the problem you are seeing on your setup. ATB, Mark.
