Raspberry Pi 3 image spec (fork)

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

This fork adds compatibility with the Raspi 3B+.

Option 1: Downloading an image

See https://github.com/chschlue/raspi3-image-spec/releases 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/chschlue/raspi3-image-spec
cd raspi3-image-spec
git checkout experimental

Then, you can generate the image by issuing the following:

umask 022
sudo env -i LC_CTYPE=C.UTF-8 PATH="/usr/sbin:/sbin:$PATH" \
    ./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=64k oflag=dsync status=progress

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”

Note that the default firewall rules only allow SSH access from the local network. If you wish to enable SSH access globally, first change your root password using passwd. Next, issue the following commands as root to remove the corresponding firewall rules:

nft flush ruleset

This will allow SSH connections globally until the next reboot. To make this persistent, remove the line "tcp dport ssh reject with tcp reset" in /etc/nftables.conf.
