Interfacing between FPGA(Xilinx) / Jetson Xavier

[Tey]

Hello,

I’m working on designing a platform which consists of a Jetson Xavier on a carrier board which is connected to a FPGA board. A couple of questions propped up so im wondering if anyone has answers to.

The initial direction is to use Pcie for communication, as in a cable running from the FPGA PCIe edge connector to the carrier board containing the xavier nx. However most if not all jetson boards available don’t have a pcie slot. I do see alot of mpcie slots but those are orientated towards m.2 storage?

is it possible to use a converter cable FPGA → PCIe → mPCIe > Jetson?

Are there any other suitable interfaces that would be better?

Are there any boards available with gen 2/3 PCIe interfaces?

I’m looking for the most painless way of communication.

Thanks,

Thanks for the additional resources, So would mean that its possible to interface with the fpga using PCIe via M.2 2280 socket? I cant see why not right?

Hi, it depends on your choice. For Xavier NX, you can refer to below devkit user guide for the interface info of Xavier NX devkit, all are standard ports that should have no problem to connect to external device.
