2 | 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 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```). | |

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. | |
