Setup Lakka on Raspberry Pi

Lakka configuration

1. Connect Ethernet cable or connect to WiFi from GUI.
2. Turn on SSH in Services

Static IP

Connect via ssh:

ssh root@lakka.local

Edit WiFi settings:

$ vi /storage/.cache/connman/wifi_XXXXXX_managed_psk/settings

Change IP method to manual and set local_address:

[wifi_XXXXXX_managed_psk]
Name=XXXXXXXXXX
SSID=XXXXXXXXXXXXXXXXXXXX
Favorite=true
AutoConnect=true
Passphrase=XXXXXXXX
Frequency=2437
Modified=2020-07-04T15:47:43.045286Z
IPv4.method=manual
IPv4.netmask_prefixlen=24
IPv4.local_address=192.168.0.113
IPv4.gateway=192.168.0.1
IPv6.method=off
IPv6.privacy=disabled

Restart WiFi:

$ connmanctl disable wifi
$ connmanctl enable wifi
$ connmanctl connect wifi_XXXXXX_managed_psk

The same for the wired connection (you have to connect cable first to see this config):

$ vi /storage/.cache/connman/ethernet_XXXXXX_cable/settings

On local machine for easy access can be added: ~/.ssh/config:

Host lakka.wlan
    UserKnownHostsFile ~/.ssh/known_hosts.wlan.lakka
    Hostname 192.168.0.113

Host lakka.eth
    UserKnownHostsFile ~/.ssh/known_hosts.eth.lakka
    Hostname 192.168.0.111

Then to connect to ssh via WiFi:

$ ssh root@lakka.wlan

Set timezone

echo "TIMEZONE=Europe/Amsterdam" > /storage/.cache/timezone

Fix HDMI Audio

To edit config.txt remount /flash with write access:

mount /flash -o remount,rw
vi /flash/config.txt

Add new lines into configuration file:

# Normal HDMI mode with sound
hdmi_drive=2
hdmi_force_edid_audio=1

Use closest to power HDMI port.

Bluetooth controller

Disable bluetooth ertm to have Xbox one controller paired with bluetooth.

Create file /etc/modprobe.d/bluetooth.conf with content:

options bluetooth disable\_ertm=Y

Verify if it’s work after reboot:

cat /sys/module/bluetooth/parameters/disable_ertm
Y

Where Y is disabled and N enabled.

Pair using bluetoothctl.

Copy BIOSes/ROMs

scp BIOS/* root@lakka.eth:system/

Add missing box-arts as PNG files only.
