NanoBTS Problem

[Stuart Baggs]

I would like to know how to downgrade my openbsc to get this BTS online (just for testing). I tried to use the git commands from Holger, but no luck so far.

$ git bisect start -- openbsc/
$ git bisect bad HEAD
$ git bisect good 0.9.0

$ cd openbsc/; make (and if I have link errors or such I would downgrade 
libosmocore too... I would downgrade by checking out the releases).

Is there anyway I can get this BTS setup and working in the short term?

Thanks, Stuart
