+
−Preparing the development and build environment
+
−===============================================
+
−
+
−In order to compile our FreeCalypso Magnetite firmware, you will need a
+
−Unix/Linux system.  Even though we are using a compiler which we got in the
+
−form of Windows .exe binaries and thus have to use Wine (see below), everything
+
−that we have built on top of it is Unix-based.  The Mother currently uses
+
−Slackware Linux release 14.2 (32-bit) and previously used Slackware 13.37,
+
−also 32-bit.
+
−
+
−You will need to install the following 3 pieces of software on whatever
+
−machine you will use to run the FC Magnetite build process:
+
−
+
−1. Wine: self-explanatory.  The Mother uses the following Slackware package:
+
−
+
−   https://www.freecalypso.org/members/falcon/slackware/wine-1.5.23-i486-1sg.txz
+
−
+
−   I originally used it with Slackware 13.37 and I am still able to use it
+
−   with 14.2 without any issues.
+
−
+
−2. FreeCalypso Wine environment:
+
−
+
−   ftp://ftp.freecalypso.org/pub/GSM/TI_src/wine/installed-env.tar.xz
+
−
+
−   Extract the content of the above tarball into your ~/.wine/drive_c
+
−   directory - that's all there is to it!
+
−
+
−3. nowhine wrapper around Wine:
+
−
+
−   ftp://ftp.freecalypso.org/pub/GSM/TI_src/wine/nowhine.c
+
−
+
−   The purpose of this wrapper is to suppress the following obnoxious whine
+
−   which wine emits on my system:
+
−
+
−   preloader: Warning: failed to reserve range 00010000-00110000
+
−
+
−   Wine will also emits a bunch of other whines if you have to run it
+
−   in an environment without an X11 display (e.g., on a machine that you
+
−   ssh into), and our nowhine wrapper suppresses those as well.
+
−
+
−   If wine does not emit those preloader whines on your system and you
+
−   never find yourself in a situation of having to run without an X11
+
−   display and thus you find our nowhine wrapper to be unnecessary,
+
−   you can skip the wrapper and create a nowhine symlink pointing directly
+
−   to wine.
+
−
+
−The mokosrec2bin flash image file format conversion utility is now included
+
−locally and no longer needs to be provided externally.
+
−
+
−Compiling the local helper utilities
+
−====================================
+
−
+
−(cd helpers; make)
+
−
+
−Do the above.  Most of the build helper scripts used in the FC Magnetite build
+
−system are written in Bourne shell, but a few were easier to implement in C.
+
−You need to compile these C helper utilities before you can run an actual FC
+
−Magnetite firmware build, but these utilities are totally ad hoc and specific
+
−to the needs of our fw build system, hence they are not meant to be installed
+
−globally on your system - instead they stay within the fc-magnetite tree.  You
+
−just need to run make in the helpers directory once before any actual firmware
+
−builds.
+
−
+
−Actually building the firmware
+
−==============================
+
−
+
−In order to build our FreeCalypso Magnetite firmware for a particular target in
+
−a particular configuration, run a command like this from the top level of the
+
−fc-magnetite tree:
+
−
+
−./configure.sh fcdev3b hybrid
+
−
+
−The first required argument to the configure.sh script selects the target, the
+
−second required argument selects the build configuration recipe, and any further
+
−arguments beyond these two (optional) allow changing various configurable
+
−settings that aren't strictly fixed by the hardware target or by the build
+
−configuration recipe.
+
−
+
−As of this writing, the following hardware targets are supported:
+
−
+
−c11x		Motorola C11x/12x
+
−c139		Motorola C139/140
+
−dsample		TI's D-Sample C05 board (no working radio currently)
+
−fcdev3b		FreeCalypso FCDEV3B
+
−gtamodem	The Calypso GSM/GPRS modem in Openmoko GTA01/02 smartphones
+
−pirelli		Pirelli DP-L10
+
−
+
−For the available configurations (the second required argument to the configure
+
−script), look in the configs directory and read the various write-ups under doc.
+
−
+
−Each configuration is built in its own directory; the name of this build
+
−directory takes the form of build-$TARGET-$CONFIG$SUFFIX, i.e., for the example
+
−configure.sh line above, the resulting build directory will be named
+
−build-fcdev3b-hybrid.  The $SUFFIX part is empty by default, but can be set on
+
−the command line in order to distinguish non-standard builds that had some
+
−tunable settings changed to values other than the default.  For example, if you
+
−are building the hybrid configuration for the fcdev3b target as above, but you
+
−need to disable MELODY_E2, you could run the configure script as follows:
+
−
+
−./configure.sh fcdev3b hybrid MELODY_E2=0 SUFFIX=-noe2
+
−
+
−The build directory would then become build-fcdev3b-hybrid-noe2, and the
+
−specified suffix will also be included in the firmware version ID string that
+
−gets compiled into the image.
+
−
+
−To actually compile the firmware, cd into the created build directory and run
+
−make there.  Unfortunately the use of TI's proprietary compiler via Wine makes
+
−the build quite slow, but there is a trick to speed it up: if you run some
+
−other Wine program that stays open and does not exit on its own (e.g., wine cmd)
+
−in another window and leave it open while you run your FC Magnetite fw build,
+
−the build will proceed much faster - the presence of another Wine process using
+
−the wineserver environment will keep Wine from shutting this environment down
+
−and restarting it for every individual cl470 run, i.e., for each individual C
+
−source file.
+
−
+
−When the build is done, the flashable firmware image will be in fwimage.bin.
+
−This image is to be flashed with fc-loadtool at address 0x10000 on Mot C11x and
+
−C139 targets, and at address 0 on the more sensible targets that have the
+
−Calypso boot ROM enabled.  The build system also produces a short text file
+
−named flash-script which is a flashing command script for fc-loadtool that
+
−erases the correct range of flash sectors and then programs fwimage.bin at the
+
−right address.
+
−
+
−When building firmware for the FCDEV3B or for the Pirelli, one can build either
+
−a flashable image or a RAM-loadable one - or both.  Because this part of the
+
−build system is common with other targets for which only flash images can be
+
−produced, the Makefile always builds the flashable image by default -
+
−fwimage.bin is always meant for flash and never for RAM.  To build a RAM-
+
−loadable image when the target allows it, run 'make ram' - the image will be in
+
−ramimage.srec, which you can then load and run on the target with FreeCalypso
+
−host tool fc-xram.
+
−
+
−Running on the hardware
+
−=======================
+
−
+
−In order to run the firmware you have built on your Calypso phone or modem
+
−(flash or run in RAM as appropriate), you will need to use FreeCalypso host
+
−tools.  As of this writing, the latest packaged release is this one:
+
−
+
−ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/fc-host-tools-r8.tar.bz2
