Wheberth,

What you're trying to do sounds possible, but I think you're approaching it
the wrong way. When you use the USRP with a default FPGA image
(usrp_x310_fpga_HG.lvbitx), you just get the HG image that you can
interface with using the NI-USRP driver in LabVIEW. In that case,
everything you program is on the host side. With this HG image, you're
pretty much just getting default RFNoC under the hood with a few changes
including header modifications. The project isn't available and wouldn't be
useful to you for integrating your code, even if you had it.

You'll want to use your X310 as a USRP RIO and interact with it via the
LabVIEW FPGA module (or something along those lines, I'm not particularly
familiar with this paradigm myself). This will give you a blank block
diagram to implement your IP and pass data over DMA to the host while
preserving the static logic necessary to allow the radio to work as you'd
expect. This is all LabVIEW and no UHD/GR. You might poke around some of
the USRP RIO examples [1] to see how similar functionality has been
implemented before you drop yours in. Beyond that, reaching out to NI
Support might be a good call for follow up questions.
