I'm supposed to start by building the GENERIC-MMCCAM kernel. 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 see 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?

Here you can search through the history of the mailinglist. https://lists.freebsd.org/archives/freebsd-arm/date.html Look for WiFi/SDIO/RPI kind of subjects. The latest I found about this subject: https://lists.freebsd.org/archives/freebsd-arm/2020-October/022626.html. I don't know anything about the current state. But a USB-WiFi dongle might be a reasonable shortcut. I'll cc the Bjoern from this e-mail. @bjoern: do you have a status update? Regards, Ronald.
