I know this is an old post, but I am desperate and saw you are using v 1.3.2.
I have an Orange Pi 5 v 1.3.2 as well and I can't get it to boot. I have been trying a bunch of different OS's, Ubuntu and Ambian versions and it keeps failing. ChatGPT and Gemini both say it is a bad DBT file and then point me to the same version of Ambian to use. None of it seems to work, have you had any luck getting it to work? I haven't tried compiling the OS yet for it, I was hoping there was a stable version out there I could use.
