The Raspberry Pi 3 is a version of the RaspberryPi which was released in February 2016. It contains a 1.2 GHz ARM Cortex-A53 CPU and hence is the first version of the RaspberryPi to support the arm64 architecture.

Debian buster runs on the Raspberry Pi 3, but there are a few issues preventing us from releasing an official image:

Longer-term improvements:

Any help on these issues is very welcome!

Preview image

To install the (unofficial, unsupported!) preview image on the SD card /dev/sdb, use:

$ wget
$ xzcat 2018-01-08-raspberry-pi-3-buster-PREVIEW.img.xz | dd of=/dev/sdb bs=64k oflag=dsync status=progress

If resolving client-supplied DHCP hostnames works in your network, you should be able to log into the Raspberry Pi 3 using SSH after booting it:

$ ssh root@rpi3
# Password is “raspberry”

You can use sysfs to configure and control the GPIO pins. The pin numbers are offset by 458 (see /sys/kernel/debug/gpio). Thus to enable pin 4 (as root):

# echo "462" > /sys/class/gpio/export

Unfortunately most Python GPIO libraries are unusable under arm64, as they try to detect the CPU revision from /proc/cpuinfo. The issue is tracked here:
