Hi, i've ported Snappy to Cubox-i and Hummingboard devices. You can find precompiled kernel and uboot packaged as "device part" at https://github.com/dz0ny/snappy-cubox-i/releases/tag/v0.0.2. Repository itself also contains patches and build script for porting almost any device with kernel 3.14 to Snappy system. Happy Hacking!
