[yocto-ab] Fwd: Re: [yocto] anyone building for the arrow sockit eval board?

Tue Jun 4 10:58:30 PDT 2013

I just pinged my contact there. For what it's worth, they do claim an
official BSP:

http://www.altera.com/devices/processor/arm/cortex-a9/software/soc-yocto-embedded-linux.html

but it isn't listed on the YP website.
