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

This is a miniPCIe. Me also need an adapter to connect an NVMe SSD with an M2 key. I can't find one. 0 Quote Link to post Share on other sites
thc013 8 Posted March 3 Share Posted March 3 Yeah it is a m2 slot and just 2 lanes and there are nvme ssd with a m2 key they are called m2 ssd they copied the m2 slot of the rk3399 board to a pcie/m2 slot with a flex cable so more as 2x pcie is not gonna happen i get today that pcie board , just in time i fixed yesterday the typc boot option in uboot the pinebook and the helios gave the solution rk3399 is not that good in bringing up all rails in 1 time and they do it in the board c file instead with the dts file 0 Quote Link to post Share on other sites
jstefanop 1 Posted March 5 Author Share Posted March 5 They only expose one PCIE lane on that adapter, and it won't work with M.2 directly or run at Gen2. Might release our custom board, 2x lanes, Gen2 running stable ~1TB/s bandwidth. 0 Quote Link to post Share on other sites
disablewong 0 Posted Wednesday at 08:41 AM Share Posted Wednesday at 08:41 AM hello jstefanop! Have you released your custom board at last>? I want to use the orangepi with my NvME SSD and 10Gbps network card but it seems not detect neither of them..... with the mini-pcie to PCI-E converter and PCIE hub it could not boot at all..... Did you built your own kernel to get it working? 0 Quote Link to post Share on other sites
