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:
vmdb2, the successor of vmdebootstrap, not yet included in Debian at that time ( late 2017 ?? ).
- The Bluetooth module is untested.
The hardware still needs a non-free binary blob to boot (included in the raspi3-firmware package). A free software replacement is being worked on.
Any help on these issues is very welcome!
To install the (unofficial, unsupported!) preview image on the SD card /dev/sdb, use:
$ wget https://people.debian.org/~stapelberg/raspberrypi3/2018-01-08/2018-01-08-raspberry-pi-3-buster-PREVIEW.img.xz $ 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: https://github.com/raspberrypi/linux/issues/2110
