Long time (commercial) = unix expert. Not much FBSD. I=E2=80=99m running Linux right now on NanoPi NEO (Allwinner H3) and NEO = 2 (Allwinner H5). Not because I love Linux (I don=E2=80=99t) but because = it works out of the box including I2C. I=E2=80=99d really like to use = FBSD on them. I hope that they will reach the same maturity as BB soon. Perhaps I=E2=80=99m wrong but my impression following this list and = searching around is that I2C and SPI are not =E2=80=9Cout of the box=E2=80= =9D with FBSD on these platforms. I=E2=80=99m not all that familiar with FDT. I=E2=80=99d like to learn = how to master it. If I understood it better I could probably bring = anything I needed to life. BUT, that is back burner to actually = completing the projects I=E2=80=99m trying to complete (where I just = need I2C access from user land). I really need those things to just work = out of the box for now - or have clear instructions on how to enable. In short I can=E2=80=99t use FBSD yet because it doesn=E2=80=99t appear = ready for these kinds of apps on these devices. I greatly appreciate all = the effort that has and is going on to get there. If I had the knowledge = I=E2=80=99d love to help, but I don=E2=80=99t currently. Perhaps I=E2=80=99ve just not searched and read enough to find the jewel = document that explains all the FDT magic in sufficient detail. By that I = mean *current* FDT magic (which is another confusing aspect as things = seem to be in flux). Any advice on these matters greatly appreciated. > On Mar 18, 2019, at 12:58 PM, Ian Lepore wrote: > I would never recommend that anybody use any flavor of rpi for any > purpose at all.
