I installed the Cluster HAT 2.5 on a Raspberry Pi 4 Model B, filling the ports with 4 Raspberry Pi Zero 2s. I installed both 32 bit and 64 bit operating systems, with cnat and cbridge on the controller cards. Every time I get the same error message -19:
hub 4-0: config failed hub doesn’t have any ports. When I run clusterctrl status, none of the ports appear to be populated.
None of the lights for P1-4 light up. There appears to be problems with your images, your board, or both. When I run a Raspberry Pi zero 2, some file appears to be missing and it fails to accept input from my keyboard.
