Yes, agreed. I will work to document this in meta-intel so others can choose to use it if they would like. Patrik did a lot of work for us on this in support of the Minnowboard "pro-bono", so I want to make sure we make use of his work. For now, that will have to be documentation. -- Darren Hart Yocto Project - Linux Kernel Intel Open Source Technology Center _______________________________________________ meta-intel mailing list [email protected] https://lists.yoctoproject.org/listinfo/meta-intel
