1 1 # rpi23-gen-image
2 2 ## Introduction
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```).
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```).

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 ##### `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.

153 152
154 153 #### Basic system features:
155 154 ##### `ENABLE_CONSOLE`=true
156 155 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.
157 156
158 157 ##### `ENABLE_PRINTK`=false
159 158 Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
160 159
161 160 ##### `ENABLE_BLUETOOTH`=false
162 161 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/
163 162
164 163 ##### `ENABLE_MINIUART_OVERLAY`=false
165 164 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.
166 165
167 166 ##### `ENABLE_TURBO`=false
168 167 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.
169 168
170 169 ##### `ENABLE_I2C`=false

306 305 Sets the QEMU enviornment for the Debian archive. If not set, `QEMU_BINARY` will be set to "/usr/bin/qemu-aarch64-static" automatically if building for arm64.
307 306
308 307 ##### `KERNEL_DEFCONFIG`="bcm2709_defconfig"
309 308 Sets the default config for kernel compiling. If not set, `KERNEL_DEFCONFIG` will be set to "bcmrpi3\_defconfig" automatically if building for arm64.
310 309

313 312
314 313 ##### `KERNEL_THREADS`=1
315 314 Number of parallel kernel building threads. If the parameter is left untouched the script will automatically determine the number of CPU cores to set the number of parallel threads to speed the kernel compilation.
316 315
317 316 ##### `KERNEL_HEADERS`=true
318 317 Install kernel headers with built kernel.
319 318
320 319 ##### `KERNEL_MENUCONFIG`=false

324 323 Run `make olddefconfig` to automatically set all new kernel configuration options to their recommended default values.
325 324
326 325 ##### `KERNEL_CCACHE`=false
327 326 Compile the kernel using ccache. This speeds up kernel recompilation by caching previous compilations and detecting when the same compilation is being done again.
328 327
329 328 ##### `KERNEL_REMOVESRC`=true
330 329 Remove all kernel sources from the generated OS image after it was built and installed.

334 333
335 334 ##### `KERNELSRC_CLEAN`=false
336 335 Clean the existing kernel sources directory `KERNELSRC_DIR` (using `make mrproper`) after it was copied to the chroot and before the compilation of the kernel has started. This parameter will be ignored if no `KERNELSRC_DIR` was specified or if `KERNELSRC_PREBUILT`=true.
337 336
338 337 ##### `KERNELSRC_CONFIG`=true
339 338 Run `make bcm2709_defconfig` (and optional `make menuconfig`) to configure the kernel sources before building. This parameter is automatically set to `true` if no existing kernel sources directory was specified using `KERNELSRC_DIR`. This parameter is ignored if `KERNELSRC_PREBUILT`=true.
340 339
341 340 ##### `KERNELSRC_USRCONFIG`=""
342 341 Copy own config file to kernel `.config`. If `KERNEL_MENUCONFIG`=true then running after copy.
343 342
344 343 ##### `KERNELSRC_PREBUILT`=false
345 344 With this parameter set to true the script expects the existing kernel sources directory to be already successfully cross-compiled. The parameters `KERNELSRC_CLEAN`, `KERNELSRC_CONFIG`, `KERNELSRC_USRCONFIG` and `KERNEL_MENUCONFIG` are ignored and no kernel compilation tasks are performed.
346 345
347 346 ##### `RPI_FIRMWARE_DIR`=""
348 347 The directory (`firmware`) containing a local copy of the firmware from the [RaspberryPi firmware project](https://github.com/raspberrypi/firmware). Default is to download the latest firmware directly from the project.
349 348
350 349 ---
351 350

359 358 Remove all doc files (harsh). Configure APT to not include doc files on future `apt-get` package installations.
360 359
361 360 ##### `REDUCE_MAN`=true
362 361 Remove all man pages and info files (harsh). Configure APT to not include man pages on future `apt-get` package installations.
363 362
364 363 ##### `REDUCE_VIM`=false
365 364 Replace `vim-tiny` package by `levee` a tiny vim clone.
366 365
367 366 ##### `REDUCE_BASH`=false
368 367 Remove `bash` package and switch to `dash` shell (experimental).

377 376 Remove all `locale` translation files.
378 377
379 378 ---
380 379
381 380 #### Encrypted root partition:
382 381 ##### `ENABLE_CRYPTFS`=false
383 382 Enable full system encryption with dm-crypt. Setup a fully LUKS encrypted root partition (aes-xts-plain64:sha512) and generate required initramfs. The /boot directory will not be encrypted. This parameter will be ignored if `BUILD_KERNEL`=false. `ENABLE_CRYPTFS` is experimental. SSH-to-initramfs is currently not supported but will be soon - feel free to help.
384 383
385 384 ##### `CRYPTFS_PASSWORD`=""
386 385 Set password of the encrypted root partition. This parameter is mandatory if `ENABLE_CRYPTFS`=true.
387 386
388 387 ##### `CRYPTFS_MAPPING`="secure"
389 388 Set name of dm-crypt managed device-mapper mapping.
390 389
391 390 ##### `CRYPTFS_CIPHER`="aes-xts-plain64:sha512"
392 391 Set cipher specification string. `aes-xts*` ciphers are strongly recommended.
393 392
394 393 ##### `CRYPTFS_XTSKEYSIZE`=512
395 394 Sets key size in bits. The argument has to be a multiple of 8.
396 395

402 401
403 402 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
404 403 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.
405 404
406 405 ## Understanding the script
407 406 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:
408 407
409 408 | Script | Description |
410 409 | --- | --- |
411 410 | `10-bootstrap.sh` | Debootstrap basic system |
412 411 | `11-apt.sh` | Setup APT repositories |
413 412 | `12-locale.sh` | Setup Locales and keyboard settings |
414 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
413 | `13-kernel.sh` | Build and install RPi 0/1/2/3 Kernel |
415 414 | `14-fstab.sh` | Setup fstab and initramfs |
416 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
415 | `15-rpi-config.sh` | Setup RPi 0/1/2/3 config and cmdline |
417 416 | `20-networking.sh` | Setup Networking |
418 417 | `21-firewall.sh` | Setup Firewall |
419 418 | `30-security.sh` | Setup Users and Security settings |
420 419 | `31-logging.sh` | Setup Logging |
421 420 | `32-sshd.sh` | Setup SSH and public keys |
422 421 | `41-uboot.sh` | Build and Setup U-Boot |
423 422 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
423 | `43-videocore.sh` | Build and Setup videocore libraries |
424 424 | `50-firstboot.sh` | First boot actions |
425 425 | `99-reduce.sh` | Reduce the disk space usage |
426 426
427 427 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.
428 428
429 429 | Directory | Description |
430 430 | --- | --- |
431 431 | `apt` | APT management configuration files |
432 | `boot` | Boot and RPi2/3 configuration files |
432 | `boot` | Boot and RPi 0/1/2/3 configuration files |
433 433 | `dpkg` | Package Manager configuration |
434 434 | `etc` | Configuration files and rc scripts |
435 435 | `firstboot` | Scripts that get executed on first boot |
436 436 | `initramfs` | Initramfs scripts |
437 437 | `iptables` | Firewall configuration files |
438 438 | `locales` | Locales configuration |
439 439 | `modules` | Kernel Modules configuration |
440 440 | `mount` | Fstab configuration |
441 441 | `network` | Networking configuration files |
442 442 | `sysctl.d` | Swapping and Network Hardening configuration |
443 443 | `xorg` | fbturbo Xorg driver configuration |
444 444
445 445 ## Custom packages and scripts
446 446 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`.
447 447
448 448 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
449 449
450 450 ## Logging of the bootstrapping process
451 451 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:
452 452
453 453 ```shell
454 454 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
455 455 ```
456 456
457 457 ## Flashing the image file
458 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`.
458 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`.
459 459
460 460 ##### Flashing examples:
461 461 ```shell
462 462 bmaptool copy ./images/buster/2017-01-23-rpi3-buster.img /dev/mmcblk0
463 463 dd bs=4M if=./images/buster/2017-01-23-rpi3-buster.img of=/dev/mmcblk0
464 464 ```
465 465 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
466 466 ```shell
467 467 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-frmw.img /dev/mmcblk0
468 468 bmaptool copy ./images/buster/2017-01-23-rpi3-buster-root.img /dev/sdc
469 469 ```
470 470
471 471 ## QEMU emulation
472 472 Start QEMU full system emulation:
473 473 ```shell
474 474 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"
475 475 ```
476 476
477 477 Start QEMU full system emulation and output to console:
478 478 ```shell
479 479 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
480 480 ```
481 481
482 482 Start QEMU full system emulation with SMP and output to console:
483 483 ```shell
484 484 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
485 485 ```
486 486
487 487 Start QEMU full system emulation with cryptfs, initramfs and output to console:
488 488 ```shell
489 489 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
490 490 ```
