−You are looking at the top level of the freecalypso-sw source code tree.
+
−The subtrees of this source tree are as follows:
+
−
+
−loadtools	The suite of tools which run on a development host machine
+
−		(normally PC/Linux desktop or laptop) and communicate with
+
−		Calypso targets.  Starting from the Calypso ROM bootloader,
+
−		these tools allow you to peek and poke registers, read and
+
−		program flash, and load and execute experimental code in IRAM
+
−		or XRAM.
+
−
+
−nuc-fw		Nucleus-based firmware.  This tree contains the early beginnings
+
−		of my (Michael Spacefalcon's) attempt to recreate TI's GSM
+
−		firmware suite running under Nucleus RTOS.  The current code is
+
−		in the earliest embryonic stages of development, and does not
+
−		do anything useful yet.  The RTOS code is FreeNucleus, based on
+
−		the Nucleus PLUS sources liberated by comrade XVilka and ported
+
−		to build with gcc and run on the Calypso by Spacefalcon the
+
−		Outlaw.
+
−
+
−target-utils	These are utilities which run on Calypso targets, but which are
+
−		independent of Nucleus, of any other RTOS, and of any larger
+
−		firmware suite, i.e., totally standalone.  The two current
+
−		utilities are loadagent, which is common for all currently
+
−		supported Calypso targets and is required in order to use
+
−		fc-loadtool or fc-xram (see loadtools), and pirexplore - the
+
−		latter is a hardware exploration utility specific to the
+
−		Pirelli DP-L10 target.
+
−
+
−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 nuc-fw or target-utils.
