jstefanop 1 Posted December 11, 2020 Share Posted December 11, 2020 What is the current pcie link speed set for stable Armbian 5.9.x release? I know stock kernels from orange pi have it set to Gen 1 speed. Need to test some Gen 2 hardware and see if it works. 0 Quote Link to post Share on other sites

We have Gen1 by default as it's the only one that's officially supported by Rockchip with RK3399: https://github.com/armbian/build/blob/master/patch/kernel/rockchip64-current/add-board-orangepi-4.patch#L839 You can however try switching it to Gen2 with pcie-gen2 overlay (overlays=pcie-gen2 in /boot/armbianEnv.txt) and see how it goes: https://github.com/armbian/build/blob/master/patch/kernel/rockchip64-current/general-rockchip-overlays.patch#L70 0 Quote Link to post Share on other sites

Is there a similar setting for link width? Its currently picking up a x4 Gen 3 M.2 drive with both link speed downgraded to gen 1 (as expected), and width downgraded to 1x. Should be 2x. 0 Quote Link to post Share on other sites

Which adapter do you use to connect the M2 for PCIE port on the orange pi 4? I can't find. 0 Quote Link to post Share on other sites
