I replaced dead chips on rpi3B and 3B+ with cm3+ BCM2837B0. Most everything works but wifi doesn't. Tried using rpi3's dtb or cm3's dtb with dtoverlay=sdio, got the same error in dmesg:
CM3+ chip on rpi3B:CM3+ chip on rpi3B+:cat /sys/class/mmc_host/mmc1/mmc1:0001/vendor
Seems the wifi chip is recognised but driver is unhappy with it. What should I do next?
CM3+ chip on rpi3B:
