Well, After a bit of "hacking" removing the "impossible instructions" trying to determine is this system (not Intel or AMD) has AVX/AVX2 in the FreeDV GUI Ver 1.4, it actually runs and doesn't crash in 2020 mode.
At this point, I have what looks like a working FreeDV 2020 app. No success on Fedora 29 on an i3 8100 or Ubuntu 18.04 on a current Pentium bought last week. H110 motherboard, bought for this job!! Both crash often and always when [Stop] is pressed. CPU load on the Berry, running a remote X session (ssh -Y user@host ) in 2020 mode, no audio from a real radio yet. With Waterfall: 60% of one CPU core With Spectrum: 30% or one CPU core In short, light load.
