Unfortunatly this is not possible for my setup. I have a Asrock J4050 with its soldered cpu. So I need something like a separate device. USB, SBC with lan, anything like that… Because of that, I was happy when i discovered coral. And to be honest: I did not researched deeply. So I am unaware of its limitation to frigate. I wanted to create my own model and run it on coral. The training was planned to be done on another device.

Now I need to check if a raspi could be sufficent or if anything else comes up.

Do you know whether they plan to introduce a newer TPU instead?

Well, good to know. I planned to buy one and attach it to my homeserver ಠ╭╮ಠ

I think this plan needs to be replaced.
