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 c155 Motorola C155/156 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 gtm900mgc Huawei GTM900, hardware variant MGC1GSMT or MGC2GSMT j100 Sony Ericsson J100 leonardo TI Leonardo boards pirelli Pirelli DP-L10 tangomdm Tango modem with MCSI 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 a target-dependent base address. 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.
