Raspberry Pi 3 image spec

This repository contains the files with which the image referenced at https://wiki.debian.org/RaspberryPi3 has been built.

Option 1: Downloading an image

See https://wiki.debian.org/RaspberryPi3#Preview_image for where to obtain the latest pre-built image.

Option 2: Building your own image

If you prefer, you can build a Debian buster Raspberry Pi 3 image yourself. For this, first install the requirements of vmdb2. Then run the following:

git clone --recursive https://github.com/Debian/raspi3-image-spec
cd raspi3-image-spec

Then edit raspi3.yaml to select the Debian repository that you want to use:

• If you want to use the snapshot with which the build was tested, use http://snapshot.debian.org/archive/debian/20171007T213914Z/. This is what is pre-configured in raspi3.yaml. However, due to a missing feature on snapshots, to make the build work, you have to disable an expiration check by APT. To do so, edit raspi3.yaml to replace all apt-get invocations with apt-get -o Acquire::Check-Valid-Until=false
• If you want to use the latest versions of each software, you can replace http://snapshot.debian.org/archive/debian/20171007T213914Z/ in raspi3.yaml with http://deb.debian.org/debian. Of course, this means that the build may break if there are regressions in the latest versions.

Once you have edited raspi3.yaml, you can generate the image by issuing the following:

umask 022
sudo env -i ./vmdb2/vmdb2 --output raspi3.img raspi3.yaml --log raspi3.log

Installing the image onto the Raspberry Pi 3

Plug an SD card which you would like to entirely overwrite into your SD card reader.

Assuming your SD card reader provides the device /dev/sdb, copy the image onto the SD card:

sudo dd if=raspi3.img of=/dev/sdb bs=5M

Then, plug the SD card into the Raspberry Pi 3 and power it up.

The image uses the hostname rpi3, so assuming your local network correctly resolves hostnames communicated via DHCP, you can log into your Raspberry Pi 3 once it booted:

ssh root@rpi3
# Enter password “raspberry”
