−You are looking at the top level of the freecalypso-sw source code tree.  The
+
−primary aim of this project is to produce our own full-source GSM firmware that
+
−would fully operate the TI Calypso-based GSM phones and modems of interest to
+
−us; this primary subproject is being worked on in the gsm-fw subtree.  While
+
−that project is progressing very slowly, the associated side projects have
+
−already produced some useful tools for operating on these GSM devices; see
+
−README.hosttools for the details.
+
−
+
−The subtrees of this source tree are as follows:
+
−
+
−gsm-fw		This tree contains the early beginnings of my (Michael
+
−		Spacefalcon's) attempt to recreate TI's GSM firmware suite for
+
−		modems and basic phones, consisting of Nucleus RTOS, RiViera
+
−		and GPF frameworks, TI's BSP/driver and L1 code, Condat G23
+
−		GSM/GPRS protocol stack, AT command interpreter and UI layers.
+
−
+
−		At the present, none of the actual GSM code (L1 or G23) has
+
−		been integrated yet, but most of the underlying RTOS environment
+
−		is present and working: one can exercise RVT, ETM, FFS and GPF,
+
−		running on gtamodem, pirelli, c139 and c155 targets.  The next
+
−		steps are to port and integrate first L1, then G23 from the
+
−		LoCosto source.
+
−
+
−target-utils	This tree contains code that runs on Calypso targets, but is
+
−		not regular firmware (gsm-fw) or a part thereof.  The two key
+
−		components built in this tree are loadagent (needed for all
+
−		targets) and compalstage (for Compal phones only), which need
+
−		to be installed on the user's host system in order for
+
−		loadtools (see README.hosttools) to do their job.
+
−
+
−ffstools	Tools that run on a Unix or GNU/Linux host; see README.hosttools
+
−loadtools	for the details.
+
−miscutil
+
−rvinterf
+
−
+
−toolchain	Scripts and patches for building the gcc+binutils toolchain
+
−		targeting ARM7, the CPU core of the Calypso GSM/GPRS baseband
+
−		processor.  You'll need to build and install this toolchain
+
−		first before you can build gsm-fw or target-utils.
