I've made a small wrapper repo on github with submodules for edison-linux (branch edison-3.10.98) and edison-bcm43340 that makes it quick and easy to build new edison-linux kernels without having to use Yocto.
After cloneing the wrapper repo, a simple
is all you need to build an edison-linux kernel with the default configuration from the edison firmware images. You can update an Edison firmware image using
DFU=../edison-image-latest/ sudo make install
or copy your new kernel and modules to a running Edison using
scp -r * email@example.com:/
Kernel config files are included in the wrapper repo for both the default edison firmware images as well as a more inclusive config that makes Edison a good headless server.
