Fairphone 2 (fairphone-fp2)/Downstream kernel

From postmarketOS

This page is only meant as a reference for the v3.4 downstream Linux kernel that is offered during pmbootstrap init. While some features work better than on mainline kernel I don't recommend using it for anything apart from debugging.

WiFi

Using NetworkManager (preinstalled) doesn't work for me / my WiFi network because of some dhcp issue.

Enable the device-fairphone-fp2-nonfree-firmware package with the mainline kernel during pmbootstrap init

Create your wpa_supplicant.conf file in /etc/wpa_supplicant/wpa_supplicant.conf, start with adding you WiFi SSID and passphrase :

# wpa_passphrase "YOUR SSID" "YOUR PASSPHRASE" > /etc/wpa_supplicant/wpa_supplicant.conf

Add the following lines to the top of the file :

ctrl_interface=/run/wpa_supplicant
update_config=1

Then run as root on the device:

# Stop NetworkManager as it interferes with wpa_supplicant
service networkmanager stop
# Start wpa_supplicant
wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf

Try without the -Dnl80211 option if it doesn't work.

Connect to a network using this guide.

# Start a DHCP client on the wlan0 interface to get an IP address
udhcpc -iwlan0

Then you should have a working WiFi connection!

Audio

For audio, read pmaports!38 for now until it's more integrated.
