Bus Mastering DMA on Xavier NX

Hi,

I’m working on Xavier NX that is connected to Xilinx FPGA through PCIe (Xavier NX as endpoint). I need to transfer buffer (say 12MB in size) between two boards (in both direction). I supposed to use bus mastering DMA on Xavier NX to perform this. But, I didn’t get any supported documents or similar examples on xavier side. Can anybody help me…?

Thanks all…
