RK3399 M.2 SATA

weckso · Posted at 4/11/2017 03:44:30

I have installed an M.2 SATA 2242 SSD on my RK3399. It doesn't appear to show up at all under Linux - is there something I'm missing?

thanks

I have a similar problem: I've inserted a M.2 -> SATA converter [1] and attached a sata harddrive, but the drive is not showing up in Linux. I've looked at `lsblk` and `lspci` (the latter results in an error) with no luck.

i think I saw that the kernel needs to be configured for support in another thread

Do you have a link?

I just tried with the latest beta image: https://drive.google.com/drive/f ... gAqAN0hWd1FMN1Zjb0k

... still no dice.

Do I have to use the official adapter board? http://shop.t-firefly.com/goods.php?id=52

Or do I have to use a different kernel to get pci/m.2 support?

I have done some research, the kernel looks like it has PCI enabled in the config (how/if it's implemented I do not know) and I'm now leaning toward u-boot needing some configuration to use the PCIe bus. I have reached out to support but no reply from them at this time.

I did just get confirmation on the #linux-rockchip irc channel that someone has actually gotten pci working but not with the firefly. He pointed me to the https://github.com/rockchip-linux/kernel project and said the 4.4 kernel is what he used. He was also kind enough to show where in the device tree pci was defined https://github.com/rockchip-linux/kernel/blob/release-4.4/arch/arm64/boot/dts/rockchip/rk3399-firefly-linux.dts#L744 Now, last time I looked through the firefly SDK source and compiled a kernel I did notice that device tree was not enabled in the .config so unless I misunderstood something, the kernel will need to be compiled with device tree support to properly use the pci bus. This should include m.2 SSD devices also.

Is there actually SATA support on the M.2 slot or is it PCI-E only? Seems strange they made the decision to put the mini PCI-E port on the bottom instead of the M.2 (would have had space for a full size 2280 drive there). Problem here is that if there is no SATA support on the M.2 - you can't really find PCI-E drives in that form factor so you have to use an awkward adapter card.

I just tried again with the latest `Firefly-rk3399_xubuntu1604_201704271809` image - it still doesn't work...

Hi
did you get the "/dev/block/nvme0n1p1" when insert your pci-e devices.?
