IIRC the PCIe interface is not compatible with GPUs.
- geerlingguy 6y agoIt may be, but nobody has proven it yet... the biggest issue is lack of ARM video drivers :( I might pick up an older PCIe card and see how far I can get using it with the CM4.
- 0-_-0 6y agoI think it's proven it doesn't work because the RPi CPU doesn't have enough BAR (Base Address Register) space. More details in this discussion: https://news.ycombinator.com/item?id=20399652 https://news.ycombinator.com/item?id=20399652
