Re: [Openbts-discuss] OpenBTS with Raspberry Pi

[Shaddi H. <sh...@cs...>]

Huh, interesting. I was under the impression that 700MHz was way too
underpowered so I didn't put too much effort into it. I will give it
another shot and report back. Did you all do anything to take advantage of
any DSP on that board? Was it also running with a RAD1?

Shaddi -

We have managed to (barely) run a combination 5 beacon plus 1 TCH/F on a
500 MHz Gumstix Overo. So I would expect that you see better performance.
Not a lot better, but better.

Yes, we were using a kernel that had hardware floating point support
enabled (the official Raspian one).

Nicholas: we just followed the normal build instructions for OpenBTS and
built it on the rPi itself. I don't recall having to do anything special.
Our pi had a 700MHz chip, we did not try overclocking it or anything.
