Let's play with the Osmocom BB stuff.
Hardware
We have:
1 x J100i 4 x C115
some others.
1 x USRP (for openbts testing)
Paul has just got a Pirelli DP-L10
Progress
So far, osmocombb's been built, and the bus pirate will allow us to upload the image, but we keep getting DOWNLOAD NACK. This is probably due to the buspirate being pretty crap at anything timing related. Try using a proper level shifting cable such as the makerbots.
Cables (headphone connector):
* Blue/copper, green/white: Ground (brown) * Blue/green: MOSI (grey) * Green/red: MISO (black)
Using Makerbot connector:
* Blue/copper, green/white: Ground (1, black) * Blue/green: MISO (4, orange) * Green/red: MOSI (5, yellow)
