The CrowPi2 system image (buster) is available HERE.
The CrowPi2 system image (bookworm) is available HERE.
Note: It's normal for your system to restart once when booted for the first time, in order to expand the filesystem automatically.
Run the Raspberry Pi Setup Wizard, it will guide you through the process.
sudo piwiz
