I write some configs to make it automatic build image weekly, here is the project:
It's simply patch 0001-Zsun.patch to the latest 17.01 code and build it.
Files download there (sdk and image builder include):

NOTE that I lost my wireless hardware last month when I weld the ttl, so there is NO TEST for those images.
