Here's the console transcript which shows the issue.

You need to clone this repo with the ssh option instead of via https. Alternatively, you can replace the md380 url in https://github.com/redfast00/brandmeister-dmr-sea/blob/master/.gitmodules with the https version of the repo.

Note that I can't really give support for any of my code for the time being, since I have exams until the beginning of February.

Edit: I just saw that this is step 0 in the README, shame on me for not testing it. I'd accept a PR that changes the md380tools url in .gitmodules if you'd like, otherwise I'll probably fix it sometimes near the beginning of February
