Hello. I am trying to split PCIe x8 controller on AGX Orin into eight x1 devices. I found several topics on this forum implying this is not supported (no bifurcation, no sufficient configuration available), however, none of them suggest a solution. Can you suggest a way to connect multiple x1 PCIe devices to a single x8 controller of AGX Orin? What kind of chip is needed here: switch, bridge, other?
At the end, what I need to achieve is one 10 GbE port and eight 1 GbE ports. My idea is to use eight PCIe x1 GbE controllers, but the more I read this forum the more it seems to not be possible. Can you guide me towards a possible solution?
The reason that Jetson itself cannot do this is because there are no 8 controllers to drive 8 x1.
You can try to use a pcie switch or bridge. For Jetson native PCIe controller, what it can support is just as the design guide document mentioned.
