# Raspberry Pi image specs
|
||
|
||
This repository contains the files with which the images referenced at
|
||
https://wiki.debian.org/RaspberryPiImages have been built.
|
||
|
||
## Option 1: Downloading an image
|
||
|
||
See https://wiki.debian.org/RaspberryPiImages 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 image
|
||
yourself. If you are reading this document online, you should first
|
||
clone this repository:
|
||
|
||
```shell
|
||
git clone --recursive https://salsa.debian.org/raspi-team/image-specs.git
|
||
cd image-specs
|
||
```
|
||
|
||
For this you will first need to install the following packages on a
|
||
Debian Buster (10) or higher system:
|
||
|
||
* vmdb2
|
||
* dosfstools
|
||
* qemu-user-static
|
||
* binfmt-support
|
||
* time
|
||
|
||
Do note that –at least currently– vmdb2 uses some syntax that is available
|
||
only in the version in testing (Bullseye).
|
||
|
||
This repository includes a master YAML recipe (which is basically a
|
||
configuration file) for all of the generated images, diverting as
|
||
little as possible in a parametrized way. The master recipe is
|
||
[raspi_master.yaml](raspi_master.yaml).
|
||
|
||
A Makefile is supplied to drive the build of the recipes into images —
|
||
`raspi_0w` (for the Raspberry Pi 0, 0w and 1, models A and B),
|
||
`raspi_2` (for the Raspberry Pi 2, models A and B), `raspi_3`
|
||
(for all models of the Raspberry Pi 3), and `raspi_4` (for all
|
||
models of the Raspberry Pi 4). That is, if you want to build the
|
||
default image for a Raspberry Pi 3B+, you can just issue:
|
||
|
||
```shell
|
||
make raspi_3.img
|
||
```
|
||
|
||
You might also want to edit them to customize the built image. If you
|
||
want to start from the platform-specific recipe, you can issue:
|
||
|
||
```shell
|
||
make raspi_3.yaml
|
||
```
|
||
The recipe drives [vmdb2](https://vmdb2.liw.fi/), the successor to
|
||
`vmdebootstrap`. Please refer to [its
|
||
documentation](https://vmdb2.liw.fi/documentation/) for further
|
||
details; it is quite an easy format to understand.
|
||
|
||
Copy the generated file to a name descriptive enough for you (say,
|
||
`my_raspi.yaml`). Once you have edited the recipe for your specific
|
||
needs, you can generate the image by issuing the following (as root):
|
||
|
||
```shell
|
||
vmdb2 --rootfs-tarball=my_raspi.tar.gz --output \
|
||
my_raspi.img my_raspi.yaml --log my_raspi.log
|
||
```
|
||
|
||
This is, just follow what is done by the `_build_img` target of the Makefile.
|
||
|
||
## Installing the image onto the Raspberry Pi
|
||
|
||
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/mmcblk0`
|
||
(**Beware** If you choose the wrong device, you might overwrite
|
||
important parts of your system. Double check it's the correct
|
||
device!), copy the image onto the SD card:
|
||
|
||
```shell
|
||
sudo dd if=raspi_3.img of=/dev/mmcblk0 bs=64k oflag=dsync status=progress
|
||
```
|
||
|
||
Then, plug the SD card into the Raspberry Pi, and power it up.
|
||
|
||
The image uses the hostname `rpi0w`, `rpi2`, `rpi3`, or `rpi4` depending on the
|
||
target build. The provided image will allow you to log in with the
|
||
`root` account with no password set, but only logging in at the
|
||
physical console (be it serial or by USB keyboard and HDMI monitor).
