No need to program a raspberry pi first. I was just trying to say that the binary that works for a raspberry pi can also be executed as well on the Apollo. The package you are looking for is the latest linux_armv6.tar.gz suffixed file from https://github.com/jstefanop/bfgminer/releases since you probably wouldn't want to try to compile a more recent version from source.

Regarding the ui part: it could possibly make sense to have it in a public github repository since it doesn't have any binary files resulting in all the source being readable directly from the sd card image. That way, those with suitable skills could more easily propose changes using pull requests. Unless of course, there's some licensing issue restricting this. I did at least notice that the bfgminer with Moonlander driver is in github (with more recent changes than the latest release) but the Apollo driver isn't there apart from a branch that did appear to be mainly a unused fork.
