Hi, Just wanted to share boot success on T-Firefly board ( http://www.t-firefly.com/en/): https://github.com/tsgan/rockchip/blob/master/RK3288/rk3288-dmesg-multi-user.txt It has Rockchip RK3288 SoC (quad core Cortex A17), unfortunately there is down side, no public Doc/TRM released yet. The basic support codes need to be polished. Ganbold
