I have been compiling images for OpenWRT for nearly five years but hit a brick wall today trying to upload code to a piece of hardware that is supposedly a WIP.

I am dealing with a serial connected U-Boot session on a Buffalo LS421DE. I have several compiled images from the current DD trunk but it seems that everything is compressed as a tarball...

Decompressing the tarball ( tar -xvf openwrt*.tar) I am left with files labeled CONTROL, root, and kernel.

What I need is a zImage to run through mkimage to get a uImage for U-Boot or a way to get a compiled uImage.

I have no idea what file compression I am dealing with after the tarball... In the V=s output from the compilation I see multiple mentions of a uImage being made or manipulated but I have no idea where to go looking for it or what sequence of decompression steps that need to be taken in order to extract it.

Is there some odd directory where just the raw uImage or zImage goes before compression is applied to it?

Thanks... Any input is welcome.
