Problem: I can't connect to any network at all. Neither netctl works, nor iwd/iwctl. My dmesg | grep brcm shows this error:
Direct firmware load for brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-zero.txt failed with error -2
Solution: It seems that the kernel module is expecting your firmware configuration file to be at "brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-zero.txt", but it is unable to find it there. Copy the firmware configuration file related to your chip (Banana Pi M2 Zero uses "AP6212") using this command:
# cp /usr/lib/firmware/brcm/brcmfmac43430-sdio.AP6212.txt /usr/lib/firmware/brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-zero.txt
Problem: I can't resolve any domain names. It seems that DNS isn't working, but ping seems to work fine. Solution: This is because of your date and time settings. Use time synchronization, or even better, an RTC module. For a temporary workaround, take a look at this.
