Can I use a M.2 to PCIe X4 cable connected from M.2 Key E Slot on Jetson Nano Carrier board to a Xilinx FPGA XDMA

No idea that, it seems you also opened another topic: Error: No PCIe DMA channels were identified while running run_test.sh on Nvidia Jetson Nano which is connected to XILINX Artix-7 A7 FPGA - Jetson & Embedded Systems / Jetson Nano - NVIDIA Developer Forums
Please help to give update. Thanks
