I want to connect 4 Jetson Tx2 to a PCIe switch for the communication between them.
So i will set one Jetson Tx2 as a PCIe root and other three would be PCIe end-point mode.
my question is that whether TX2 could be set to PCIe end-point mode. And whether my application could be working?

TX2’s PCIe has support only for root port mode of operation. It can’t work as an end point.
Although, if the PCIe switch you are planning to use supports Non-Transparent Bridging (NTB), then, that feature of the switch can be used to make inter TX2 communication with having TX2s continue to work in RP mode.
