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!
After further investigation both on this forum and other sources and multiple attempts with various uboots and kernels, I have concluded that either my NVMe adapter board/ribbon cable is dead or my Pinebook Pro mainboard is partly defective (all other hardware appears to work) and can't communicate with the adapter. :/
I plan to further test the former possibility with continuity and voltage checks on the adapter board itself. I also have a final NVMe drive to test that is arriving Saturday.
Unfortunately, both the NVMe board and the spare Pinebook Pro mainboards are currently out of stock, so I can't order more of those to try.
I am also concerned given that Samurai_Crow said that there is currently a power supply issue with new Pinebook Pro boards and the NVMe adapter. Perhaps this is design defect and not just a one-off thing . . .
If any one has any further thoughts or ideas, please let me know. I got this Pinebook Pro in part to be able to play with NVMe and PCIe in general on ARM Thanks!
