I wouldn't bother trying to reverse-engineer the GSM firmware itself. The technical and legal barriers are too high for this to be a practical approach. Just accept that it is a black box, like the hard drive in your PC. However, it would be useful to talk about "reverse-engineering" and documenting the AT command set through which the GSM chipset is accessed. Much of it is standard, but there are some proprietary commands. It would be very useful if we could find (for example) commands to control echo suppression/cancellation in the Calypso chipset. These wiki pages are a good starting point: http://wiki.openmoko.org/wiki/Hardware:AT_Commands http://wiki.openmoko.org/wiki/GTA01_and_GTA02_gsm_modem _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
