Is communication through Ethernet over pcie in r36.4.3 same as pcie to pcie communication between two jetson agx orin 64gbs ? like speed, etc. ? ---

Are you talking about PCIe endpoint mode? ---

Yes, that one. But actually we are unable to transfer the data from end-point to root-port over direct pcie to pcie communication. ---

I am not quite sure about what does your “same” mean here in the comment. Compare to what kind of usecase? The pcie endpoint mode on Ethernet interface has some other network overhead on it so may not be as fast as direct transfer. ---

ok got this one. So, can you help us to transfer the data from rootport to endpoint over pcie to pcie. Already, we have followed the steps in documentation of r36.4.3, but unable. ---

You should provide logs and what did you do on your side step by step. Please do not just tell me “it cannot work”. This provide nothing helpful. ---

Just follow this document. > **[PCIe Endpoint Mode — NVIDIA Jetson Linux Developer Guide](https://docs.nvidia.com/jetson/archives/r36.4.3/DeveloperGuide/SD/Communications/PcieEndpointMode.html#bringing-up-an-ethernet-interface-over-pcie)** I don’t know what you are doing there but looks like you didn’t use tegra vnet driver at all. ---

tegra\_vnet is for ethernet over pcie right … that is working fine and succesfully pinging on both sides. But we want direct pcie to pcie communication for Bi directional file transfer. ---

I don’t get what you need here. tegra\_vnet can do what you want too. tegra\_vnet or pcie\_dma\_test are all sample drivers here. If it cannot achieve what you need, then please modify them by yourself. ---

pcie\_dma\_test there is no kernel to user level API. I am unable to see sending and receiving the data. Is there any reference to read and Write into BARs. Or please confirm me pcie-epf-nv test will work in R35.4.1 same pcie-epf-nv test will work for R36.4.3? ---

That driver is deprecated on rel-36.4.3 and no work anymore. If you want that, maybe trying to port that to rel-36.4.3. ---
