[leon-anavi]

Enable AMPAK AP6330 that combines Broadcom Wifi (BCM4330) and Bluetooth 4.0 (BCM40183) chips for sun9i devices such as Merrii A80 Optimus and Cubieboard 4.

QA

Tested with an open 2.4GHz WiFi network on Merrii A80 Optimus board here are the results:

• The dmesg log:

Configuration

Follow the steps below to configure the WiFi:

• Built an image with wpa-supplicant, for example in conf/local.conf:

IMAGE_INSTALL:append = " wpa-supplicant"

• create directory /etc/wpa_supplicant/

• Create /etc/wpa_supplicant/wpa_supplicant-wlan0.conf with the following content:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
country=BG

network={
  ssid="Leon-P9"
  key_mgmt=NONE
  scan_ssid=1
}

Note: replace the ssid with whatever you are using.

• Create /etc/systemd/network/70-wlan.network with the following content:

[Match]
Name=wlan0

[Network]
DHCP=ipv4

After creating these two files restart the networking systemd services:

systemctl restart systemd-networkd.service
systemctl restart [email protected]
