I saw this document: https://downloadcenter.intel.com/download/23197/Intel-Quark-BSP
There is a new BSP version 1.2 On the Build guide it says
There is Galileo Gen2, but does that release also works on Galielo Gen1?
"Intel® Galileo Customer Reference Board (CRB) (Fab D with blue PCB)" means Galileo Gen1.
So it is supported.
