Well I was able to build by changing the docker image with this option : DOCKER_ARMBIAN_BASE_IMAGE=ubuntu:jammy The two other images (debian:bookworm and ubuntu:noble) simply do not work

Hey Sam, busy week so only getting around to replying - yes there are pre-built images for it but we took them down because I wasn't happy with the state it was in. We have a patch we're cleaning up that add the packages for GPU Acceleration and Wifi/BT that we're going to merge today/this weekend so I will re-enable the image generation and it will show up under Supported boards tomorrow/Sunday. If you do end up getting it and trying it out feel free to reach out here or on discord and let me know if you run into anything.

It has been like this since it's May release. Torrent download also fails keeps rejecting fragments presumably due mismatching checks. Is suspect the file got corrupted somehow

endgoal is Device 1 is reachable from PC1 - with PC1 settings all can NOT be changed and ideally Device1 on completely different subnet...

Not to forget this: What is your endgoal here? You just want to ping 'device 1' from PC1 ? Or you want to connect to 'device 1' from PC1 using some protocol? Gr,
