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
20 20 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh
21 21 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh

25 25 BUILD_KERNEL=true ENABLE_MINBASE=true ENABLE_IPV6=false ./rpi23-gen-image.sh
26 26 BUILD_KERNEL=true KERNELSRC_DIR=/tmp/linux ./rpi23-gen-image.sh
27 27 ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
28 28 ENABLE_CRYPTFS=true CRYPTFS_PASSWORD=changeme EXPANDROOT=false ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
29 29 RELEASE=stretch BUILD_KERNEL=true ./rpi23-gen-image.sh
30 30 RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=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.

153 156 ---
154 157
155 158 #### Basic system features:
156 159 ##### `ENABLE_CONSOLE`=true
157 160 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.
158 161
159 162 ##### `ENABLE_PRINTK`=false
160 163 Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
161 164
162 165 ##### `ENABLE_BLUETOOTH`=false
163 166 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/).
164 167
165 168 ##### `ENABLE_MINIUART_OVERLAY`=false
166 169 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.
167 170
168 171 ##### `ENABLE_TURBO`=false
169 172 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.
170 173
171 174 ##### `ENABLE_I2C`=false

173 176
174 177 ##### `ENABLE_SPI`=false
175 178 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.
176 179
177 180 ##### `ENABLE_IPV6`=true

447 450
448 451 ## Understanding the script
449 452 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:
450 453
451 454 | Script | Description |
452 455 | --- | --- |
453 456 | `10-bootstrap.sh` | Debootstrap basic system |
454 457 | `11-apt.sh` | Setup APT repositories |
455 458 | `12-locale.sh` | Setup Locales and keyboard settings |
456 459 | `13-kernel.sh` | Build and install RPi 0/1/2/3 Kernel |
457 460 | `14-fstab.sh` | Setup fstab and initramfs |
458 461 | `15-rpi-config.sh` | Setup RPi 0/1/2/3 config and cmdline |
459 462 | `20-networking.sh` | Setup Networking |
460 463 | `21-firewall.sh` | Setup Firewall |
461 464 | `30-security.sh` | Setup Users and Security settings |
462 465 | `31-logging.sh` | Setup Logging |
463 466 | `32-sshd.sh` | Setup SSH and public keys |
464 467 | `41-uboot.sh` | Build and Setup U-Boot |
465 468 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
466 469 | `43-videocore.sh` | Build and Setup videocore libraries |
467 470 | `50-firstboot.sh` | First boot actions |
468 471 | `99-reduce.sh` | Reduce the disk space usage |
469 472
470 473 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.
471 474
472 475 | Directory | Description |
473 476 | --- | --- |
474 477 | `apt` | APT management configuration files |
475 478 | `boot` | Boot and RPi 0/1/2/3 configuration files |
476 479 | `dpkg` | Package Manager configuration |
477 480 | `etc` | Configuration files and rc scripts |
478 481 | `firstboot` | Scripts that get executed on first boot |
479 482 | `initramfs` | Initramfs scripts |
480 483 | `iptables` | Firewall configuration files |
481 484 | `locales` | Locales configuration |
482 485 | `modules` | Kernel Modules configuration |
483 486 | `mount` | Fstab configuration |
484 487 | `network` | Networking configuration files |
485 488 | `sysctl.d` | Swapping and Network Hardening configuration |
486 489 | `xorg` | fbturbo Xorg driver configuration |
487 490
488 491 ## Custom packages and scripts
489 492 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`.
490 493
491 494 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
492 495
493 496 ## Logging of the bootstrapping process
494 497 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:
495 498
496 499 ```shell
497 500 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
498 501 ```
499 502
500 503 ## Flashing the image file
501 504 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`.
502 505
503 506 ##### Flashing examples:
504 507 ```shell
505 508 bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
506 509 dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
507 510 ```
508 511 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
509 512 ```shell
510 513 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
511 514 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
512 515 ```
513 516
514 517 ## QEMU emulation
515 518 Start QEMU full system emulation:
516 519 ```shell
517 520 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"
518 521 ```
519 522
520 523 Start QEMU full system emulation and output to console:
521 524 ```shell
522 525 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
523 526 ```
524 527
525 528 Start QEMU full system emulation with SMP and output to console:
526 529 ```shell
527 530 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
528 531 ```
529 532
530 533 Start QEMU full system emulation with cryptfs, initramfs and output to console:
531 534 ```shell
532 535 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
533 536 ```
