But even my installation via serial fails.Is that via a standard ttl serial adapter? I believe that at this point, specifically the debug probe that Mark mentioned is required, connected to the 3-pin header. AFAIK the GPIO pins as used on earlier Pi machines will not work here.Better I wait for the OBSD 7.8-stable.We are currently in the wind-down towards 7.8 so unless changed soon, this will be how things look for 7.8.Firstly I used a standard ttl serial adaptor (which was very very often used for installation of OBSD on RaspberryPi 4B and BananaPi M5). But 3 days ago I bought the debug probe, and had the same result: nothing comes over the serial. It makes me crazy to read here that some other guys successfully installed OBSD, but not me.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
