	1	## Templates used at IFÉ ENS de Lyon for "Tremplin des sciences" project
	2
	3	These templates have been used to create Raspberry Pi images for the
	4	project "Climate and meteorolgy springboard for teaching sciences".
	5	These images are tuned andused as explained in the
	6	[blog](http://blog.climatetmeteo.fr/GerardVidal/) (mostly in french
	7	but under translation).
	8
	9	The aim is to share with teachers a Raspberry Pi3 binary image providing software resources to use commercial weatherstations or DIY weathersystems made with various sensors. The following images have been built :
	10
	11	* raspife2-stretch Debian stretch image for raspi 2
	12	* raspife3-jessie Debian jessie image for raspi 3
	13	* raspife3-stretch Debian stretch image for raspi 3
	14	* raspife3W-stretch Debian stretch image for raspi 3 with single IPAddress and weewx service
	15	* raspife3-buster Debian buster image for raspi 3
	16
	17	In these images language ichoosen is french and can easily be changed.
	18	Pathes and other variables are the ones that have been used during
	19	execution and personnal data are replaced by "*******", change the
	20	values according to your needs.

             # rpi23-gen-image
             ## Introduction
-            `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for all Raspberry Pi computers. The script at this time supports the bootstrapping of the Debian (armhf/armel) releases `stretch` and `buster`. Raspberry Pi 0/1/2/3/4 images are generated for 32-bit mode only. Raspberry Pi 3 supports 64-bit images that can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.14.y```).
+            `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for Raspberry Pi 2 (RPi2), Raspberry Pi 3 (RPi3) and Raspberry Pi 4 (RPi4) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `jessie`, `stretch`, `buster` and 'bullseye'. Raspberry Pi 3 images are generated for 32-bit mode only. Raspberry Pi 3 and  Raspberry Pi 4 64-bit images can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.11.y```).
             ## Build dependencies
             The following list of Debian packages must be installed on the build system because they are essentially required for the bootstrapping process. The script will check if all required packages are installed and missing packages will be installed automatically if confirmed by the user.
               ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
             It is recommended to configure the `rpi23-gen-image.sh` script to build and install the latest Raspberry Pi Linux kernel. For the Raspberry 3 this is mandatory. Kernel compilation and linking will be performed on the build system using an ARM (armhf/armel/aarch64) cross-compiler toolchain.
             The script has been tested using the default `crossbuild-essential-armhf` and `crossbuild-essential-armel` toolchain meta packages on Debian Linux `stretch` build systems. Please check the [Debian CrossToolchains Wiki](https://wiki.debian.org/CrossToolchains) for further information.
             ## Command-line parameters
             The script accepts certain command-line parameters to enable or disable specific OS features, services and configuration settings. These parameters are passed to the `rpi23-gen-image.sh` script via (simple) shell-variables. Unlike environment shell-variables (simple) shell-variables are defined at the beginning of the command-line call of the `rpi23-gen-image.sh` script.
             ##### Command-line examples:

             ## Configuration template files
             To avoid long lists of command-line parameters and to help to store the favourite parameter configurations the `rpi23-gen-image.sh` script supports so called configuration template files (`CONFIG_TEMPLATE`=template). These are simple text files located in the `./templates` directory that contain the list of configuration parameters that will be used. New configuration template files can be added to the `./templates` directory.
             ##### Command-line examples:
             ```shell
             CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
             CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
             ```
             ## Supported parameters and settings
             #### APT settings:
             ##### `APT_SERVER`="ftp.debian.org"
             Set Debian packages server address. Choose a server from the list of Debian worldwide [mirror sites](https://www.debian.org/mirror/list). Using a nearby server will probably speed-up all required downloads within the bootstrapping process.
             ##### `APT_PROXY`=""
             Set Proxy server address. Using a local Proxy-Cache like `apt-cacher-ng` will speed-up the bootstrapping process because all required Debian packages will only be downloaded from the Debian mirror site once. If `apt-cacher-ng` is running on default `http://127.0.0.1:3142` it is autodetected and you don't need to set this.
             ##### `KEEP_APT_PROXY`=false
             Keep the APT_PROXY settings used in the bootsrapping process in the generated image.
             ##### `APT_INCLUDES`=""
             A comma-separated list of additional packages to be installed by debootstrap during bootstrapping.
             ##### `APT_INCLUDES_LATE`=""
             A comma-separated list of additional packages to be installed by apt after bootstrapping and after APT sources are set up.  This is useful for packages with pre-depends, which debootstrap do not handle well.

             #### Basic system features:
             ##### `ENABLE_CONSOLE`=true
             Enable serial console interface. Recommended if no monitor or keyboard is connected to the RPi2/3. In case of problems fe. if the network (auto) configuration failed - the serial console can be used to access the system. On RPI `0` `3` `3P` the CPU speed is locked at lowest speed.
             ##### `ENABLE_PRINTK`=false
             Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
             ##### `ENABLE_BLUETOOTH`=false
             Enable onboard Bluetooth interface on the RPi0/3/3P. See: [Configuring the GPIO serial port on Raspbian jessie and stretch](https://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3/).
             ##### `ENABLE_MINIUART_OVERLAY`=false
             Enable Bluetooth to use this. Adds overlay to swap UART0 with UART1. Enabling (slower) Bluetooth and full speed serial console. - RPI `0` `3` `3P` have a fast `hardware UART0` (ttyAMA0) and a `mini UART1` (ttyS0)! RPI `1` `1P` `2` only have a `hardware UART0`. `UART0` is considered better, because is faster and more stable than `mini UART1`. By default the Bluetooth modem is mapped to the `hardware UART0` and `mini UART` is used for console. The `mini UART` is a problem for the serial console, because its baudrate depends on the CPU frequency, which is changing on runtime. Resulting in a volatile baudrate and thus in an unusable serial console.
             ##### `ENABLE_TURBO`=false
             Enable Turbo mode. This setting locks cpu at the highest frequency. As setting ENABLE_CONSOLE=true locks RPI to lowest CPU speed, this is can be used additionally to lock cpu hat max speed. Need a good power supply and probably cooling for the Raspberry PI.

             Set a filename for the output file(s). Note: the script will create $IMAGE_NAME.img if `ENABLE_SPLITFS`=false or $IMAGE_NAME-frmw.img and $IMAGE_NAME-root.img if `ENABLE_SPLITFS`=true. Note 2: If the KERNEL_BRANCH is not set, the word "CURRENT" is used.
             ## Understanding the script
             The functions of this script that are required for the different stages of the bootstrapping are split up into single files located inside the `bootstrap.d` directory. During the bootstrapping every script in this directory gets executed in lexicographical order:
             | Script | Description |
             | --- | --- |
             | `10-bootstrap.sh` | Debootstrap basic system |
             | `11-apt.sh` | Setup APT repositories |
             | `12-locale.sh` | Setup Locales and keyboard settings |
             | `13-kernel.sh` | Build and install RPi 0/1/2/3 Kernel |
             | `14-fstab.sh` | Setup fstab and initramfs |
             | `15-rpi-config.sh` | Setup RPi 0/1/2/3 config and cmdline |
             | `20-networking.sh` | Setup Networking |
             | `21-firewall.sh` | Setup Firewall |
             | `30-security.sh` | Setup Users and Security settings |
             | `31-logging.sh` | Setup Logging |
             | `32-sshd.sh` | Setup SSH and public keys |
             | `41-uboot.sh` | Build and Setup U-Boot |
             | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
             | `43-videocore.sh` | Build and Setup videocore libraries |
             | `50-firstboot.sh` | First boot actions |
             | `99-reduce.sh` | Reduce the disk space usage |
             All the required configuration files that will be copied to the generated OS image are located inside the `files` directory. It is not recommended to modify these configuration files manually.
             | Directory | Description |
             | --- | --- |
             | `apt` | APT management configuration files |
             | `boot` | Boot and RPi 0/1/2/3 configuration files |
             | `dpkg` | Package Manager configuration |
             | `etc` | Configuration files and rc scripts |
             | `firstboot` | Scripts that get executed on first boot  |
             | `initramfs` | Initramfs scripts |
             | `iptables` | Firewall configuration files |
             | `locales` | Locales configuration |
             | `modules` | Kernel Modules configuration |
             | `mount` | Fstab configuration |
             | `network` | Networking configuration files |
             | `sysctl.d` | Swapping and Network Hardening configuration |
             | `xorg` | fbturbo Xorg driver configuration |
             ## Custom packages and scripts
             Debian custom packages, i.e. those not in the debian repositories, can be installed by placing them in the `packages` directory. They are installed immediately after packages from the repositories are installed. Any dependencies listed in the custom packages will be downloaded automatically from the repositories. Do not list these custom packages in `APT_INCLUDES`.
             Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
             ## Logging of the bootstrapping process
             All information related to the bootstrapping process and the commands executed by the `rpi23-gen-image.sh` script can easily be saved into a logfile. The common shell command `script` can be used for this purpose:
             ```shell
             script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
             ```
             ## Flashing the image file
             After the image file was successfully created by the `rpi23-gen-image.sh` script it can be copied to the microSD card that will be used by the RPi 0/1/2/3 computer. This can be performed by using the tools `bmaptool` or `dd`. Using `bmaptool` will probably speed-up the copy process because `bmaptool` copies more wisely than `dd`.
             ##### Flashing examples:
             ```shell
             bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
             dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
             ```
             If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
             ```shell
             bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
             bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
             ```
             ## QEMU emulation
             Start QEMU full system emulation:
             ```shell
             qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=tty1"
             ```
             Start QEMU full system emulation and output to console:
             ```shell
             qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
             ```
             Start QEMU full system emulation with SMP and output to console:
             ```shell
             qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -smp cpus=2,maxcpus=2 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
             ```
             Start QEMU full system emulation with cryptfs, initramfs and output to console:
             ```shell
             qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -initrd "initramfs-${KERNEL_VERSION}" -append "root=/dev/mapper/secure cryptdevice=/dev/mmcblk0p2:secure rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
             ```
