Hi Bill,
The instruction you listed is for standard building process. My question is how to use Board_Support_Package_Sources_for_Intel_Quark_v0.7.5_full_yocto_archive.tar.gz to build? It's different.
I assume all dependency package source files are included in xxx_full_yocto_archive file, so the bitbake can get source file from local file system instead of from network.
thanks,
Jacker
