The Block#0 issue is a known one, the problem is that it doesn't pick up the name until it invokes the DLL/.so from your custom code. It's being worked on. They should work, however, in GNU Radio where the DLL/.so *is* linked in.
You do, however, need to create block.yaml files to describe your blocks to UHD. --M On Sun, Nov 8, 2020 at 8:04 AM Dario Pennisi <da...@iptronix.com> wrote: > Hi, > I've been trying to create and use a rfnoc block for n310 within gnuradio > 3.8 and uhd4.0.
