[yocto] any success with spartan6-lx9mb?

[Adrian Alonso]

I just read most of the thread,

Is clear that another maintainer for meta-xilinx is needed :)

To summarize spartan6-lx9mb I only succeed in building an initramfs image, using
Xilinx prebuilt toolchain.

Check
recipes-core/images/initramfs-image
in microblaze-support branch

The only build step that I found are here
http://wiki.secretlab.ca/Poky_Linux_Microblaze_support

Which are for Microblaze in Virtex5 M507;

At the time that I was working to integrate Microblaze I never pass to
successfully build gcc (4.5.0)
but probably with newer gcc it could be different story.
