eMMC2 is new on the rpi4 and uses the sdhc(4) driver, so that description doesn't apply. But switching makes the other sdhc(4) available for the wifi. > Incidentally, the line in the dmesg that > bwfm0: failed loadfirmware of file brcmfmac43455-sdio.bin > Is that a problem? Run fw_update and reboot. The wifi should work after that.
