But they stopped developing the brcmfmac-Wifi-drivers for some unknown = reason. The last time I looked into it on the Pi : sdio didn=E2=80=99t work for = a simple reason :=20 There was a missing overlay in config.txt . That=E2=80=99s one of the reasons why e.g. Mark and me often take focus = on=20 the msdos partitions environment, u-boot etc. Sometimes discussions like this sound weird but all has to do with the = other :-) For now we should have sdio working on the Pi with the MMCCAM kernel. OpenBSD used their standard SD-driver IIRC so the next step=20 would be to port parts of OpenBSD`s driver to the fbsd-sdio =E2=80=A6 somewhat superficially described but combine forces with some people = here=20 We could have a good starting point to work on a driver, with or without = the fbsd-foundation. But there should be at least one FreeBSD developer who says: Yes, that=E2=80=99s a good path to go if you guys can manage that =E2=80=A6= I also think of IOT things like LoraWan and so on but having the onboard = Wifi for brcmfmac should be a=20 good starting point, then BT and so on...but it's going to be a pretty = dirty job :-) Above Information without guarantee as I am not a FreeBSD member.
