[Discuss OpenCPI] qadc to qdac loopback

The goal is to implement a simple iqsample loopback Application from qadc to qdac on Zed+fmcomms3 to measure the round-trip delay. The Application xml is below. It fails with:
No acceptable implementations found in any libraries for "ocpi.assets.devices.ad9361_spi".
The question is: does this need an assembly with nothing in it to get the container?
