Hi Jeff, I don't know the direct answer to your question because I have not yet tried to build the example gain block. However, I have looked at the rfnoc specification (draft version) found here <https://files.ettus.com/app_notes/>. This doc is not without errors, but it does provide a good overview of changes and might help answer your question about yml files. It appears that Ettus has not yet released "noc_block_tool" which will eventually create the yml files from user input, but for now perhaps you have to just create the yml file yourself based on other example noc blocks like FIR and FFT.
