Hello Bernhard, I've recently built several headers to connect to my pi5's and I've ended up with a few that did not work. I'm using a usb -> ttl with a cable with 3 pins. I believe this is what you mean by debug probe. If you're not seeing anything in the console there are a couple things to look at: console speed, and the boot config to make sure the uart is enabled. Past that, you should see uboot come up if the console is working. If you are getting past that then we have different issues. Please test the continuity of the rx and tx side independently because I've had 2 cables now that the rx works, but tx has an open. Hopefully this helps. It does sound like you've done things correctly though. Brandon
