Kurtis Heimerl kheimerl at cs.berkeley.eduHello baseband-devel at lists.osmocom.org! I've just started my first OsmocomBB project, using a Motorola V171 and the source code in the main git repository. The short hand version of the story is that we're looking into modifying the GSM MS stack to allow for the BTS to save some power. This is research being done at the University of California, and we're sorta amazed at how wonderful OsmocomBB is for this particular project. Thanks for the work! Progress has generally been good, and I've been able to build and run the "hello world" e99 application. Following that, I've moved onto the mobile app... and run into an issue that I can't seem to resolve by searching your mailing lists. Basically, each individual process runs fine: osmocon installs the compal_e99/layer1.compalram.bin image onto a c155 device mobile connects (though it doesn't see the SIM for some reason...) and the terminal is available and active. I'm not able to do much though, as the MS isn't on yet. Upon turning the MS on, it scans for a while, eventually detecting my own cell tower. Terminal is active during this search. Unfortunately, shortly after detecting and syncing with my tower (ARFCN 51), the terminal freezes. osmocon begins repeating the following error: "Failed to write msg to the socket.." and nothing else moves. Kaput. Terminal does not respond to any messages sent. This is my problem, as I'd like to make a call.

My intuition is that I've missed setting some key variables in the related configuration files (~/.osmocom/osmocom.cfg, ~/.osmocom/bb/mobile.cfg). though I can't find ANY documentation about what's supposed to be in those things. Any and all help would be appreciated.
