2 ## Introduction
2 ## Introduction
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```).

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.

14 ## Command-line parameters
14 ## Command-line parameters
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.

34 ## Configuration template files
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.

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.

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`.
