Installation

1. Follow the steps on Installation_guide#Initialization

2. Choose the raspberry-pi4 device

3. Start the build process and install the completed image to a sdcard

$ pmbootstrap install --sdcard /dev/sdX
(replace /dev/sdX with the device for your sdcard)

4. Place the sdcard into the Raspberry Pi and boot it

Display

Screens may need to be connected at boot time, otherwise they might only display 1080p or not display anything at all (pmaports#2965).

Bluetooth

On the Raspberry Pi 4, the Bluetooth chip uses the hardware UART0 port. In postmarketOS, Bluetooth is enabled by default; this means that the hardware UART port is inaccessible.

If you want to use the hardware UART for other purposes (for example, serial debugging), edit the /boot/usercfg.txt and comment out the following line at the end of the file:

# Automatically enable Bluetooth without having to use btattach
# Note that the Pi's Bluetooth interface is connected via hardware UART;
# if you intend to use it for other purposes (for example, serial debugging)
# comment out the line below.
dtparam=krnbt=on

When this is done, Bluetooth will have to be enabled manually using btattach -B /dev/ttyAMA0 -P bcm -S 115200 -N.
