Hey Arend Thanks for taking a look. The brcmfmac-wcc module is present on my installation, but I’m not currently loading it. (I only load brcmutil, then brcmfmac.) But, even if I load it, the wlan0 interface still doesn’t show up. In the modules.dep, I see that brcmfmac-wcc should be loaded after brcmutil and brcmfmac. Is that accurate?
Yes. Actually brcmfmac loads brcmfmac-wcc by itself.
My installation is somewhat unusual in that I use a custom userland (see https://gokrazy.org/).
Bit tricky choice of name :-p I will check it out. Regards, Arend

Thanks.Strange. Could it be there is some build config needed to install the additional kernel modules (brcmfmac-wcc.ko, etc.) on RPi image?
