Preparing the development and build environment =============================================== In order to compile our FreeCalypso Tourmaline 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 Tourmaline 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. Compiling the local helper utilities ==================================== (cd helpers; make) Do the above. Most of the build helper scripts used in the FC Tourmaline 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 Tourmaline 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-tourmaline 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 Tourmaline firmware for a particular target in a particular configuration, run a command like this from the top level of the fc-tourmaline tree: ./configure.sh luna2 bigcolor-gprs The first required argument to the configure.sh script selects the hardware target, the second required argument selects the functional configuration, and any further arguments beyond these two (optional) allow changing various configurable settings that go beyond basic functional selection and aren't strictly fixed by the hardware target. As of this writing, the following hardware targets are supported: c11x Motorola C11x/12x c139 Motorola C139/140 c155 Motorola C155/156 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 luna1 FreeCalypso Luna, based on iWOW DSK v4.0 or v5.0 motherboard luna2 FreeCalypso Luna, based on FC Caramel2 motherboard pirelli Pirelli DP-L10 tangomdm FreeCalypso Tango standard modem config The second required argument selects the basic functional configuration; these functional config stanzas appear in the configs directory. The following functional configurations are currently available: bigcolor-gprs & bigcolor-vo These are UI-enabled configurations with the big (176x220 pixel) color version of the UI. These functional configs can be built only for luna1 and luna2 targets. smallbw Small B&W UI configuration - 96x64 pixel black&white UI version. This functional config can be built for c139, luna1 and luna2 targets. When running on Luna, the logical 96x64 pixel B&W LCD is centered in the middle of the 176x220 pixel physical LCD, surrounded by a pale magenta border. bwtest This one is a special intermediate configuration is that the UI layers are built in the smallbw config, but the underlying R2D framebuffer driver is 176x220 pixel B&W, rather than 96x64 pixel B&W. This config can only be built for Luna targets; it originates from TI's own configuration of running their !LSCREEN (smallbw) UI on D-Sample boards with R2D driver in the BW_D_Sample config. stdmodem Standard modem config, all data services enabled, no UI functionality included. Supported targets are fcdev3b, gtamodem, gtm900mgc and tangomdm. vpm See the Voice-pseudo-modem article. This functional config is applicable to c11x, c139, c155, j100 and pirelli targets. 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-luna2-bigcolor-gprs. 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 modem firmware for an FCDEV3B V1 board where you need to disable sleep, you should run the configure script as follows: ./configure.sh fcdev3b stdmodem DISABLE_SLEEP=1 SUFFIX=-nosleep The build directory would then become build-fcdev3b-stdmodem-nosleep, 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 Tourmaline 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. Cached libraries ================ In the build architecture of all TCS211-based firmwares including Tourmaline, each fw component is first compiled into a linkable library (*.lib file with TI's TMS470 toolchain), and then these libraries are linked together into the final code image. Early in FreeCalypso project history many of these component libraries were blobs, meaning that we had to use prebuilt libraries for which we had no corresponding source. Our fw has now been almost fully deblobbed, meaning that we have transitioned from blobs to recompilation from source for almost all of our fw components. But this deblobbing has had an unfortunate downside: because our Wine-based compiler is very slow, every time we deblobbed a component library, build times would get longer and longer. FC Tourmaline introduces a partial solution to this problem in the form of cached libs. Some component libraries are completely independent of configuration particulars, i.e., they remain exactly the same no matter which Calypso target you are building firmware for, and are likewise unaffected by our various supported functional configs. Prebuilt versions of these config- independent libs have been checked into the cache directory of our source tree, and Tourmaline fw builds use these cached libs by default. These cached libs are NOT blobs in that we do have the corresponding source for them, and the versions that are checked in have been built by us, not by any evil source- withholding third parties. You can disable the use of cached libs and force full recompilation from source by adding a USE_CACHE=0 argument to your configure.sh line. 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.
