Picking up the suggestion here I want to ask about CD8180’s PCIe ‘bifurcation’ capabilities.
As I may have understood correctly it’s not only about the SoC’s possibilities how to ‘spread’ PCIe lanes but also board layout (with RK3588 the four Gen3 lanes could be used in a 4 x x1 config but the clocks must also be considered and as such with Rock 5B only a 2 x x2 config for the M.2 slot is possible, right?)
So speaking about the PCIe x8 and the M.2 x4 slot: is it possible to use them in other configs, e.g. the PCIe slot in a 4 x x2 and the M.2 slot in a 4 x x1 or 2 x x2 setup?
