See > http://rockchip.fr/Rockchip%20RK3399%20TRM%20V1.3%20Part2.pdf > Everything I'm seeing there says Gen1 vs Gen2 depends on "PCIE_GENERATION_SEL", and that if its set to 0, you get Gen1 2.5Gt/s and if it is set to 1, you get Gen2, 5.0Gt/s. But I don't see anything specifying this value for the RockPro64 board. Drew
