Thanks that you=E2=80=99re willing to step into tests ( a very important = thing to save the devs some (testing) time=20 And give feedback on boards/machines that devs don=E2=80=99t own)! `ll try to describe mmccam in simplest human understandable words : mmccam enables the output of : 'camcontrol devlist`=E2=80=A6.=20 what will (currently)return an empty tag on the second SDIO-IC on RPI , what means that there is something available on the SDIO-bus(the = Wifi-chip), which can=E2=80=99t be initialized because of a missing driver/firmware. The brcm-wifi-chip on the RPI4 is detected over the SDIO-bus( SD means = SD-card, IO means in/out). MMC means : MultiMediaCard. CAM means: Common Access Method, which is a SCSI-subsystem in Fbsd. So Bj=C3=B6rn talks to the Wifi-chip via the SD-Card-bus which is = 'detected'=20 over the SCSI-bus in his CAM-implementation. GENERIC-MMCCAM,as Bj=C3=B6rn told,( to say in hard but friendly words = :-) Ha Ha ),=20 isn=E2=80=99t enabled by default in GENERIC(-nodebug) because it = currently doesn=E2=80=99t do anything final=20 for production-mode (e.g. on the RPI). So the best thing which could happen is that my description is totally = outdated and wrong- and you would see fully working WIFI on your RPI :-), but don=E2=80=99t = expect that for now... Good luck, Regards kls
