check data transference pcie

[enarasanz4]

I have connected a picoevb device to the Jetson Xavier and I want to exhange data from the Jetson memory to the FPGA and then from the FPGA to the Jetson memory. My project is similar to the one here: GitHub - NVIDIA/jetson-rdma-picoevb: Minimal HW-based demo of GPUDirect RDMA on NVIDIA Jetson AGX Xavier running L4T.

I have followed the instructions of the project in that github project and now I want to verify that it is working. Is there any way of verifying the transference or any tool that allows me to do it?

Doesn’t your FPGA has an internal DMA engine which and pull/push data from/to Xavier’s memory into/from FPGA’s memory? If yes, you need a driver written for your FPGA device that run on Xavier to do the job.
