According to a page that hasn't been updated for a while (https://wiki.free= bsd.org/SDIO) work is in progress on Broadcom wireless drivers for the Rasp= berry Pi 3 and 4. I'm supposed to start by building the GENERIC-MMCCAM ker= nel. A CAM device will then appear which I can then use camcontrol to talk= to. I built the kernel and booted it on my Pi 3B+, which has a Broadcom = 43455/6 according to Linux. All camcontrol finds is the mini SD card. I s= ee only one call to sdhci_init_slot in bcm2835_sdhost.c so maybe that's the= problem. It supports exactly one SDIO device, a memory card. Any thoughts? Is it worth thinking about the wireless chip or is it just t= oo much work? # camcontrol devlist <SDHC SC16G 8.0 SN 54B43C20 MFG 08/2018 > at scbus0 target 0 lun 0 (pass0,= sdda0) # camcontrol devlist -v scbus0 on sdhci_slot0 bus 0: <SDHC SC16G 8.0 SN 54B43C20 MFG 08/2018 > at scbus0 target 0 lun 0 (pass0,= sdda0) scbus-1 on xpt0 bus 0: <> at scbus-1 target -1 lun ffffffff (xpt0)
