hi everyone.is it possible to connect motorola c118 to the raspberry GPIO pins,since they are 3v3 logic? What is the current limitation as the GPIO pins can provide only 8mA? Is it possible to use the lcd of the c118 or the RTC on the raspberry pi via the GPIO pins? Can i use the connection via the GPIO Instead of the pl2303 based cable. Thanks.
hello,
the first question is it possible to compile osmocom-bb on Rasperry ?

yes its possible. See below comments.gmane.org/gmane.comp.mobile.osmocom.baseband.devel/3199

Hi All
I have tried it on Raspberry Pi. First I thought both are ARM, so no crosscompile needed. I think the hello world example worked, but nothing else.
So I searched for a crosscompile howto, and compiled another Toolchain on the Pi. That worked much better. I did not use the internal UART, but used an external USB dongle. I could use the RSSI monitor, and also the layer1 worked to some extent. I could see the phone making the channel measurements, but at the end it did not associate with any channel.
Does somebody have a setup on RPi where he/she can make actual calls (and hence associate with a cell)? If yes could you share how you did it? (maybe I compiled to the wrong platform?)
Thanx in advance
CU, Ricsi

mhh, I did it the same way. I use the raspbian image from the raspberry pi foundation. I compiled exactly this version:
http://bb.osmocom.org/trac/wiki/GnuArmToolchain
My raspberry is resetting when I pull the USB-UART Adapter. But if it is present while booting, I can use /dev/ttyUSB0 and the mobile-app is working like on x86-Architecture:
OsmocomBB# show ms MS '1' is up, service is normal IMEI: 3532900XXXXXXXX IMEISV: 353290XXXXXXXXXX IMEI generation: fixed automatic network selection state: A2 on PLMN MCC=262 MNC=07 (Germany, O2) cell selection state: C3 camped normally ARFCN=XXX(DCS) MCC=262 MNC=07 LAC=0xXXXX CELLID=0xXXXX (Germany, O2) radio ressource layer state: idle mobility management layer state: MM idle, normal service
Even OpenBTS with sylvain-testing code is working.
Cheers

hi Tim, the RPi is resetting because the motorola cxx connected via USB is drawing more current than available.have you tried using a powered usb hub? Have tried using the UART on the gpio?

how can that be? The Phone has a charger and a battery. Using TTL could not cost much of power. Or did I miss something?
But if you are right, an active USB hub would surely help. I will test that out.
Have tried using the UART on the gpio?
Not yet. That will be one of the next tasks.

hi, with osmocombb,is it possible to do voip?
