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 Raspberry Pi 2 (RPi2) and Raspberry Pi 3 (RPi3) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `stretch` and `buster`. Raspberry Pi 3 images are generated for 32-bit mode only. Raspberry Pi 3 64-bit images 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 RPi3 this is mandatory. Kernel compilation and linking will be performed on the build system using an ARM (armhf) cross-compiler toolchain.
11 11
12 12 The script has been tested using the default `crossbuild-essential-armhf` toolchain meta package 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
22 22 ENABLE_HARDNET=true ENABLE_IPTABLES=true /rpi23-gen-image.sh
23 23 APT_SERVER=ftp.de.debian.org APT_PROXY="http://127.0.0.1:3142/" ./rpi23-gen-image.sh
24 24 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/debian"
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 ##### `APT_INCLUDES`=""
52 52 A comma separated list of additional packages to be installed by debootstrap during bootstrapping.
53 53
54 54 ##### `APT_INCLUDES_LATE`=""
55 55 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.
56 56
57 57 ---
58 58
59 59 #### General system settings:
60 60 ##### `SET_ARCH`=32
61 61 Set Architecture to default 32bit. If you want to to compile 64bit (RPI3 or RPI3+) set it to `64`. This option will set every needed crosscompiler or boeard specific option for a successful build.

151 151
152 152 ---
153 153
154 154 #### Basic system features:
155 155 ##### `ENABLE_CONSOLE`=true
156 156 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.
157 157
158 158 ##### `ENABLE_PRINTK`=false
159 159 Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
160 160
161 161 ##### `ENABLE_BLUETOOTH`=false
162 162 Enable onboard Bluetooth interface on the RPi0/3/3P. See: https://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3/
163 163
164 164 ##### `ENABLE_MINIUART_OVERLAY`=false
165 165 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.
166 166
167 167 ##### `ENABLE_TURBO`=false
168 168 Enable Turbo mode. This setting locks cpu at 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.
169 169
170 170 ##### `ENABLE_I2C`=false
171 171 Enable I2C interface on the RPi2/3. Please check the [RPi2/3 pinout diagrams](https://elinux.org/RPi_Low-level_peripherals) to connect the right GPIO pins.
172 172
173 173 ##### `ENABLE_SPI`=false
174 174 Enable SPI interface on the RPi2/3. Please check the [RPi2/3 pinout diagrams](https://elinux.org/RPi_Low-level_peripherals) to connect the right GPIO pins.
175 175
176 176 ##### `ENABLE_IPV6`=true
177 177 Enable IPv6 support. The network interface configuration is managed via systemd-networkd.
178 178
179 179 ##### `ENABLE_SSHD`=true
180 180 Install and enable OpenSSH service. The default configuration of the service doesn't allow `root` to login. Please use the user `pi` instead and `su -` or `sudo` to execute commands as root.
181 181
182 182 ##### `ENABLE_NONFREE`=false
183 183 Allow the installation of non-free Debian packages that do not comply with the DFSG. This is required to install closed-source firmware binary blobs.
184 184
185 185 ##### `ENABLE_WIRELESS`=false
186 186 Download and install the [closed-source firmware binary blob](https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm) that is required to run the internal wireless interface of the Raspberry Pi model `3`. This parameter is ignored if the specified `RPI_MODEL` is not `3`.
187 187
188 188 ##### `ENABLE_RSYSLOG`=true
189 189 If set to false, disable and uninstall rsyslog (so logs will be available only in journal files)

196 196
197 197 ##### `ENABLE_MINGPU`=false
198 198 Minimize the amount of shared memory reserved for the GPU. It doesn't seem to be possible to fully disable the GPU.
199 199
200 200 ##### `ENABLE_DBUS`=true
201 201 Install and enable D-Bus message bus. Please note that systemd should work without D-bus but it's recommended to be enabled.
202 202
203 203 ##### `ENABLE_XORG`=false
204 204 Install Xorg open-source X Window System.
205 205
206 206 ##### `ENABLE_WM`=""
207 207 Install a user defined window manager for the X Window System. To make sure all X related package dependencies are getting installed `ENABLE_XORG` will automatically get enabled if `ENABLE_WM` is used. The `rpi23-gen-image.sh` script has been tested with the following list of window managers: `blackbox`, `openbox`, `fluxbox`, `jwm`, `dwm`, `xfce4`, `awesome`.
208 208

423 429
424 430 ## Understanding the script
425 431 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:
426 432
427 433 | Script | Description |
428 434 | --- | --- |
429 435 | `10-bootstrap.sh` | Debootstrap basic system |
430 436 | `11-apt.sh` | Setup APT repositories |
431 437 | `12-locale.sh` | Setup Locales and keyboard settings |
432 438 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
433 439 | `14-fstab.sh` | Setup fstab and initramfs |
434 440 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
435 441 | `20-networking.sh` | Setup Networking |
436 442 | `21-firewall.sh` | Setup Firewall |
437 443 | `30-security.sh` | Setup Users and Security settings |
438 444 | `31-logging.sh` | Setup Logging |
439 445 | `32-sshd.sh` | Setup SSH and public keys |
440 446 | `41-uboot.sh` | Build and Setup U-Boot |
441 447 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
442 448 | `50-firstboot.sh` | First boot actions |
443 449 | `99-reduce.sh` | Reduce the disk space usage |
444 450
445 451 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.
446 452
447 453 | Directory | Description |
448 454 | --- | --- |
449 455 | `apt` | APT management configuration files |
450 456 | `boot` | Boot and RPi2/3 configuration files |
451 457 | `dpkg` | Package Manager configuration |
452 458 | `etc` | Configuration files and rc scripts |
453 459 | `firstboot` | Scripts that get executed on first boot |
454 460 | `initramfs` | Initramfs scripts |
455 461 | `iptables` | Firewall configuration files |
456 462 | `locales` | Locales configuration |
457 463 | `modules` | Kernel Modules configuration |
458 464 | `mount` | Fstab configuration |
459 465 | `network` | Networking configuration files |
460 466 | `sysctl.d` | Swapping and Network Hardening configuration |
461 467 | `xorg` | fbturbo Xorg driver configuration |
462 468
463 469 ## Custom packages and scripts
464 470 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`.
465 471
466 472 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
467 473
468 474 ## Logging of the bootstrapping process
469 475 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:
470 476
471 477 ```shell
472 478 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
473 479 ```
474 480
475 481 ## Flashing the image file
476 482 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 RPi2/3 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`.
477 483
478 484 ##### Flashing examples:
479 485 ```shell
480 486 bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
481 487 dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
482 488 ```
483 489 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
484 490 ```shell
485 491 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
486 492 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
487 493 ```
488 494
489 495 ## QEMU emulation
490 496 Start QEMU full system emulation:
491 497 ```shell
492 498 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"
493 499 ```
494 500
495 501 Start QEMU full system emulation and output to console:
496 502 ```shell
497 503 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
498 504 ```
499 505
500 506 Start QEMU full system emulation with SMP and output to console:
501 507 ```shell
502 508 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
503 509 ```
504 510
505 511 Start QEMU full system emulation with cryptfs, initramfs and output to console:
506 512 ```shell
507 513 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
508 514 ```
