Nate, thanks for the update. Unfortunately, we're somewhat stuck by the "newness" of the platform. We don't have RV64G support for any Ubuntu releases prior to 21.04 (ugh!). The PR you referenced doesn't appear to be too terribly difficult to follow. I may try to manually patch my local source and make the necessary architecture mods. I know this is not the preferred path, but I may be able to crawl through this...
