Thanks that you’re willing to step into tests ( a very important thing to save the devs some (testing) time And give feedback on boards/machines that devs don’t own)! `ll try to describe mmccam in simplest human understandable words : mmccam enables the output of : 'camcontrol devlist`…. 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’t 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 Björn talks to the Wifi-chip via the SD-Card-bus which is 'detected' over the SCSI-bus in his CAM-implementation. GENERIC-MMCCAM,as Björn told,( to say in hard but friendly words :-) Ha Ha ), isn’t enabled by default in GENERIC(-nodebug) because it currently doesn’t do anything final 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 So the best thing which could happen is that my description is totally outdated and wrong- and you would see fully working WIFI on your RPI :-), but don’t expect that for now... Good luck, Regards kls _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arm To unsubscribe, send any mail to "[email protected]"
