Considering buying and question on the PCIe slot
#21
I think the time has come for ARM and chipmakers to use uefi on their chips since the u boot which is used is outdated now and as ARM is moving into laptop market, uefi might be a good use especially in driving pcie devices. With that being said, sbc makers should implement in their products the uefi for the good of its customers. Windows on ARM uses uefi, so as Linux must be.  Big Grin

Hi guys,

I've just joined the forum because I am curious if anyone has made progress on getting a Nvidia card to work with their Rockpro64 (joe2gaan?)
I do not own a board yet but am strongly considering buying one if this works.

Might the "Generic display driver" and CUDA Toolkit from https://developer.nvidia.com/cuda-toolkit-65 (See Linux ARM tab) work with this board?

I don't think NVidia card can work on ROCKPro64, this due to graphic card needs large IO Memory range.

Hey @zener, did you ever get this working?  I was looking at this board specifically to use with an Xtra, so hoping someone has blazed the trail Smile

Sorry about the late reply.

No I could not get it working. The recent PCIe driver will load, the low level test application will not crash:

But when I run the test application it will crash:

I was reading this post because of an interest in the pcie situation work the rk3399 SoCs.

I watched a presentation today from last October by some guy from ARM. The presentation was on just that topic. Do a search on "github ebbr arm" and you will find the specification they are leading work on. Good stuff.
