I've just successfully installed FriendlyWrt 22.03 on a NanoPi R5S and have some questions about updating it.
1) On the web, I've read about production builds and snapshots. Does this apply to FriendlyWrt as well? Is 22.03 the stable version as of early December 2022?
2) How is the software kept updated? I've run across references to a command "sysupdate"; does that apply to Friendly Wrt as well?
3) The wiki (section 5.8) mentions running "opkg update", but this consisstently gives me the "wget returned 8" message, even though I can reach the outsside network from the R5S. Is this the right way to initialize the package list?
