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?
