1 1 # rpi23-gen-image
2 2 ## Introduction
3 3 `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 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```).
4 4
5 5 ## Build dependencies
6 6 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.
7 7
8 8 ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
9 9
10 10 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) cross-compiler toolchain.
11 11
12 12 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.
13 13
14 14 ## Command-line parameters
15 15 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.
16 16
17 17 ##### Command-line examples:
18 18 ```shell
19 19 ENABLE_UBOOT=true ./rpi23-gen-image.sh

31 31 RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
32 32 ```
33 33
34 34 ## Configuration template files
35 35 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.
36 36
37 37 ##### Command-line examples:
38 38 ```shell
39 39 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
40 40 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
41 41 ```
42 42
43 43 ## Supported parameters and settings
44 44 #### APT settings:
45 45 ##### `APT_SERVER`="ftp.debian.org"
46 46 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.
47 47
48 48 ##### `APT_PROXY`=""
49 49 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.
50 50
51 51 ##### `KEEP_APT_PROXY`=false
52 52 Keep the APT_PROXY settings used in the bootsrapping process in the generated image.
53 53
54 54 ##### `APT_INCLUDES`=""
55 55 A comma-separated list of additional packages to be installed by debootstrap during bootstrapping.
56 56
57 57 ##### `APT_INCLUDES_LATE`=""
58 58 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.

153 153 ---
154 154
155 155 #### Basic system features:
156 156 ##### `ENABLE_CONSOLE`=true
157 157 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.
158 158
159 159 ##### `ENABLE_PRINTK`=false
160 160 Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
161 161
162 162 ##### `ENABLE_BLUETOOTH`=false
163 163 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/).
164 164
165 165 ##### `ENABLE_MINIUART_OVERLAY`=false
166 166 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.
167 167
168 168 ##### `ENABLE_TURBO`=false
169 169 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.
170 170
171 171 ##### `ENABLE_I2C`=false

173 173
174 174 ##### `ENABLE_SPI`=false
175 175 Enable SPI interface on the RPi 0/1/2/3. Please check the [RPi 0/1/2/3 pinout diagrams](https://elinux.org/RPi_Low-level_peripherals) to connect the right GPIO pins.
176 176
177 177 ##### `ENABLE_IPV6`=true

447 447
448 448 ## Understanding the script
449 449 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:
450 450
451 451 | Script | Description |
452 452 | --- | --- |
453 453 | `10-bootstrap.sh` | Debootstrap basic system |
454 454 | `11-apt.sh` | Setup APT repositories |
455 455 | `12-locale.sh` | Setup Locales and keyboard settings |
456 456 | `13-kernel.sh` | Build and install RPi 0/1/2/3 Kernel |
457 457 | `14-fstab.sh` | Setup fstab and initramfs |
458 458 | `15-rpi-config.sh` | Setup RPi 0/1/2/3 config and cmdline |
459 459 | `20-networking.sh` | Setup Networking |
460 460 | `21-firewall.sh` | Setup Firewall |
461 461 | `30-security.sh` | Setup Users and Security settings |
462 462 | `31-logging.sh` | Setup Logging |
463 463 | `32-sshd.sh` | Setup SSH and public keys |
464 464 | `41-uboot.sh` | Build and Setup U-Boot |
465 465 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
466 466 | `43-videocore.sh` | Build and Setup videocore libraries |
467 467 | `50-firstboot.sh` | First boot actions |
468 468 | `99-reduce.sh` | Reduce the disk space usage |
469 469
470 470 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.
471 471
472 472 | Directory | Description |
473 473 | --- | --- |
474 474 | `apt` | APT management configuration files |
475 475 | `boot` | Boot and RPi 0/1/2/3 configuration files |
476 476 | `dpkg` | Package Manager configuration |
477 477 | `etc` | Configuration files and rc scripts |
478 478 | `firstboot` | Scripts that get executed on first boot |

485 485 | `sysctl.d` | Swapping and Network Hardening configuration |
486 486 | `xorg` | fbturbo Xorg driver configuration |
487 487
488 488 ## Custom packages and scripts
489 489 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`.
490 490
491 491 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
492 492
493 493 ## Logging of the bootstrapping process
494 494 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:
495 495
496 496 ```shell
497 497 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
498 498 ```
499 499
500 500 ## Flashing the image file
501 501 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`.
502 502
503 503 ##### Flashing examples:
504 504 ```shell
505 505 bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
506 506 dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
507 507 ```
508 508 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
509 509 ```shell
510 510 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
511 511 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
512 512 ```
513 513
514 514 ## QEMU emulation
515 515 Start QEMU full system emulation:
516 516 ```shell
517 517 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"
518 518 ```
519 519
520 520 Start QEMU full system emulation and output to console:
521 521 ```shell
522 522 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
523 523 ```
524 524
525 525 Start QEMU full system emulation with SMP and output to console:
526 526 ```shell
527 527 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
528 528 ```
529 529
530 530 Start QEMU full system emulation with cryptfs, initramfs and output to console:
531 531 ```shell
532 532 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
533 533 ```
