Obviously not supported hardware, but wanted to throw this out in case it's of use to anyone. I picked up the mid-level CuBox-i2eX (dual-core, serial over USB, http://www.solid-run.com/products/cubox-i-mini-computer/cubox-i-specifications/) model and attempted to load the 12/14/2014 IMX snapshot (via tftp using SolidRun's Ignition image as the U-Boot source). Logs are below, let me know if there's any assistance I can in the future. Thanks.
