[poky] Need help to build poky image for beagle board

[Sparsh Wid hope]

Thanks for your guidance, I downloaded angstrom-angstrom-layers package from the link 
http://gitorious.org/angstrom/angstrom-layers/ and updated laverne-4.0.1/meta/conf, /recipes-bsp, /recipes-ti, added image recipes_images_beagleboard-demo-image.bb in /meta/recipes/core/images and modified /meta/conf/local.conf.sample as 
#MACHINE  ?="qemux86" and
MACHINE ?="beagleboard"
and bitbake it as bitbake omap-image-beagleboard-demo and got the error :
NOTE: <type 'exceptions.Exception'>:variable BBPATH references itself! while evaluating:
/home/surya/Surya/pro/POKY/laverne-4.0.1/meta:${BBPATH}

Help me to solve the problem.
Thanks in advance.

I'll address the 'beagleboard' portion of your question below.

That's not a TI overlay, it's an overlay done by someone to add the dspbridge stuff to OE. If you want better beagleboard support, use the following layer:

http://gitorious.org/angstrom/angstrom-layers/

If you don't want to manually resolve all the layer dependencies have a look at the scripts mentioned in the readme:

http://gitorious.org/angstrom/angstrom-layers/blobs/master/README

The 'better' in the above is aimed at hw support like cpufreq, DSP, 1GHz/720MHz, etc. The standard yocto kernel lacks all that because it's focussed at different things like 100% POSIX compliance.

Koen
