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 uses Slackware Linux version 13.37, 32-bit. You will need to install the following four pieces of software on whatever machine you will use to run the FC Magnetite build process: 1. Wine: self-explanatory. 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 Note that Wine may produce different whines on your system than it does on mine, in which case if you wish to be relieved of those whines, you'll need to edit my nowhine.c hack for your situation. And if wine does not whine at all on your system, you can skip the wrapper and create a nowhine symlink pointing directly to wine. 4. mokosrec2bin flash image file format conversion utility: ftp://ftp.freecalypso.org/pub/GSM/GTA02/gsm-fw/mokosrec2bin.c Note that the four host software pieces above are exactly the same as what has been needed to build our previous TCS211-based fw works such as leo2moko-debug and tcs211-c139 - thus if you have built those previously, you should already have all of the necessary host tools. 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 gtamodem l1reconst The first argument to the configure.sh script selects the target, and the second argument selects the configuration. As of this writing, the following targets are supported: c11x Motorola C11x/12x c139 Motorola C139/140 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; by default the build directory is named build-$TARGET-$CONFIG, i.e., for the example configure.sh line above, the resulting build directory will be build-gtamodem-l1reconst. You can change the name of this directory by appending a BUILD_DIR=dir argument to the ./configure.sh line after the two required arguments. 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-r7.tar.bz2 Please see target-specific notes for more details.
