Requirements

This will only work on linux machines. It will not work on macOS because there's no viable way to mount ext3/4 partitions.

Usage

Building

To build, simply run ./startCustomization.sh for the latest commits of chiptool, ot-br-posix and zap or following below syntax:

startCustomization -h                                                            # for help
startCustomization -ct <commit_hash>"                                            # commits of ot-br-posix and zap are the latest
startCustomization -otbr <commit_hash>"                                          # commits of chip-tool and zap are the latest
startCustomization -z <commit_hash>"                                             # commits of chip-tool and ot-br-posix are the latest
startCustomization -ct <commit_hash> -otbr <commit_hash> -zap <commit_hash>"     # Specific commits for ot-br-posix, chip-tool and zap are provided

This script will do the following:

• Download the base raspios image if not already downloaded
• Mount preinstalled ubuntu for raspi
• Execute custom scripts/commands
• Unmount the preinstalled ubuntu for raspi
• Package a new ubuntu image file and z it

The final .zip file will be in build/

Running scripts/commands inside the custom ubuntu image

Place any scripts you want to run inside of src. When a new script is added, make sure it to build.sh under the section that looks like this:

        # Use chroot to run any commands
        # Ex:
        #     sudo chroot "${IMAGE_MOUNT_POINT}" /bin/bash whoami
        sudo chroot "${IMAGE_MOUNT_POINT}" /bin/bash /repo/src/00-test.sh
        sudo chroot "${IMAGE_MOUNT_POINT}" /bin/bash /repo/src/01-my-new-script.sh
