NVMe doesn't show up

[ReddestDream]

Same problem as the OP. Just got a new Pinebook Pro. NVMe adapter does not work. I've tried 3 drives and none of them appear.

I think the issue, at least in my case, actually has more to do with the PCIe bus just not initializing. I've tried lspci with various forms and flags and I can't get anything to show up with or without an NVMe drive plugged in.

I suspect the relevant error involves the bit from dmesg:

Code:

rockchip-pcie f8000000.pcie: PCIe link training gen1 timeout!
rockchip-pcie: probe of f8000000.pcie failed with error -110

Not sure if this is a hardware defect or if I just need more time to play around more with uboot and/or the kernel.

Any help is greatly appreciated. Thanks!
