Selecting and preparing the compiler environment ================================================ FreeCalypso Selenite firmware can be built with two different compiler toolchains: either with TI's original TMS470 compiler or with gcc. Transition to compiling with gcc is a very bold move with very heavy fallout, and many parts of the fw are still broken or destabilized when built with gcc instead of the original compiler they were developed with, thus for the foreseeable future, anyone who aspires to be a FreeCalypso developer will need to compile our fw in both ways, compare the behaviour of the two versions, and work toward making the gcc-built version perform as well as the TMS470-built one. Thus you need to have both compiler toolchains installed and working - see the Toolchain-setup-470 and Toolchain-setup-gcc articles for the instructions. Compiling the local helper utilities ==================================== (cd helpers; make) Do the above. Most of the build helper scripts used in the FC Selenite 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 Selenite 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-selenite tree. You just need to run make in the helpers directory once before any actual firmware builds. Actually building the firmware ============================== To build our FC Selenite firmware for your hw target of interest in the default configuration, run a command like this from the top level of the fc-selenite tree: ./configure-gcc.sh fcdev3b or ./configure-tms470.sh fcdev3b 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 pirelli Pirelli DP-L10 tangomdm FreeCalypso Tango standard modem config Notice the difference from FC Magnetite: there is no "configuration name" argument after the target name. Because FC Selenite does not include any UI code (modem functionality only) and does not offer different versions of various fw components the way Magnetite does, it does not have named configurations in the same sense as Magnetite. Instead any configuration tweaks are done via var=value optional arguments on the configure command line after the required target name argument; the following variables are currently available for tweaking: ALLOW_CSIM_GSM Per TI's original design, the AT+CSIM command does not allow GSM APDUs of class 0xA0. Openmoko found some need for them, and they patched their modem fw to allow these APDUs with AT+CSIM. With our new hybrid modem fw this policy setting is configurable at build time; the default is ALLOW_CSIM_GSM=1 (GSM APDUs allowed). DISABLE_SLEEP The general default is DISABLE_SLEEP=0, and the firmware automatically enables all of the chipset's available sleep modes on boot. Setting DISABLE_SLEEP=1 causes all sleep modes to be disabled by default on boot (they can still be enabled with the AT%SLEEP command); this setting is needed for FCDEV3B V1 boards that have a hardware bug that causes breakage when sleep modes are enabled. FCHG_STATE This setting enables or disables the FCHG battery charging driver. By default it is enabled on targets that have battery charging hardware (c11x, c139, c155, pirelli) and disabled on those that don't have such hw (fcdev3b, gtamodem). GPRS Self-explanatory: enables or disables GPRS. By default GPRS is enabled on proper modem hw targets (fcdev3b and gtamodem) and disabled on c11x, c139, c155 and pirelli. L1_DYN_DSP_DWNLD This setting enables TI's dynamic DSP patch download mechanism. When the firmware is built for a Calypso target with DSP ROM version 36 in the silicon (all FreeCalypso-made hw and most of the supported legacy targets), L1_DYN_DSP_DWNLD is enabled by default and needs to be kept enabled for correct operation: the patch code we got from TI for this ROM is the dynamic download version, and the ARM-side L1 code expects all of these patches to be present, both the static part and the dynamic parts. However, one can build our fw with L1_DYN_DSP_DWNLD=0 for experimental testing, to see what breaks when the dynamic patches are omitted. L1_VOICE_MEMO_AMR This setting enables or disables support in L1 and in the RiViera Audio Service for AMR voice memo recording and playback. This code has not been properly studied yet and no test AT commands are provided for it, but it is enabled by default like in TI's original TCS211 fw. MELODY_E2 This setting enables or disables support in L1 and in the RiViera Audio Service for playing E2-format melodies. The default is MELODY_E2=1 like in TI's original TCS211 fw. Note that Melody E1 support is always enabled; setting MELODY_E2=0 disables only Melody E2, but not E1. MEMSUPER This setting enables the memory supervision feature in TI's GPF and in the G23M protocol stack built on top of it. This code has not been properly studied yet; play with it at your own risk. RVTMUX_ON_MODEM This setting configures the usage of Calypso UARTs. RVTMUX_ON_MODEM=0 puts the AT command interface on the MODEM UART and RVTMUX on the IrDA UART (TI's intended config and the default on sensible hw targets); RVTMUX_ON_MODEM=1 (default on the crippled C1xx targets) puts RVTMUX on the MODEM UART, sacrificing the standard AT command interface. SERIAL_DYNAMIC_SWITCH TI's TCS211 fw includes a provision (only for Bluetooth-enabled fw in TI's original) to switch one UART between the AT command interface and RVTMUX while the other UART is fixed for Bluetooth. In FreeCalypso we have changed this code to work without Bluetooth, for the purpose of switching the user-facing MODEM UART between AT commands and RVTMUX, but the mechanism does not work properly yet and is disabled by default. Enable it with SERIAL_DYNAMIC_SWITCH=1 if you would like to play with it. SPEECH_RECO This setting enables or disables support in L1 and in the RiViera Audio Service for TI's speech recognition mechanism. This code and the underlying DSP facility itself have not been properly studied yet and no test AT commands are provided for it, but it is enabled by default like in TI's original TCS211 fw. SRVC TI's original config variable, selects the presence or absence of data services other than GPRS as follows: SRVC=0: voice and SMS only SRVC=1: CSD and fax enabled SRVC=2: CSD enabled, but not fax The default is SRVC=1 (fax and data enabled) for proper modem hw targets (fcdev3b and gtamodem) and SRVC=0 (voice and SMS only) on c11x, c139, c155 and pirelli. SUFFIX This setting is solely for configuration management. If you make a build with any of the settings described in this document changed from the default, you should also pass a SUFFIX=-xxx argument so your special build will be appropriately identified in the build directory name and in the firmware version ID string compiled into the image. The naming of suffixes is up to you, but here are some examples: L1_DYN_DSP_DWNLD=0 SUFFIX=-nodyn MELODY_E2=0 SUFFIX=-noe2 MEMSUPER=2 SUFFIX=-ps SERIAL_DYNAMIC_SWITCH=1 SUFFIX=-sds SPEECH_RECO=0 SUFFIX=-nosr TR_BAUD_CONFIG=TR_BAUD_812500 SUFFIX=-812500 TRACEMASK_IN_FFS TI's Test Interface (TIF) component in the GPF realm includes an optional feature for saving trace masks in FFS, but TI's production firmwares had it disabled. The component in question is now compiled from source like the rest of our fw, but we still keep this TRACEMASK_IN_FFS code disabled by default, at least for now. Set TRACEMASK_IN_FFS=1 to enable this code in GPF. TR_BAUD_CONFIG The value of this symbol is an alphanumeric keyword of the form TR_BAUD_xxxxxx; the default is TR_BAUD_115200. See src/cs/drivers/drv_core/uart/traceswitch.h for the available baud rate choices; the most practical use is setting TR_BAUD_CONFIG=TR_BAUD_812500 when you need to run the RVTMUX serial channel at the maximum possible baud rate. Each configuration is built in its own directory; the name of this build directory always begins with build- and is constructed to reflect the configuration. The auto-generated build directory name includes the name of the target, the selection of services to be included based on the GPRS, SRVC and FCHG_STATE variables, and a -470 or -gcc suffix indicating the compiler toolchain, but if you manually override any of the other config variables described above, you should also include a SUFFIX=-xxx argument giving an identifying suffix for your own configuration changes. To actually compile the firmware, cd into the created build directory and run make there. With gcc the build proceeds very fast because the compiler runs natively, but building with the original TMS470 compiler requires going through Wine, which is much slower. There is, however, a trick to speed up these TMS470 builds: 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 Selenite TMS470 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 FCDEV3B or other Calypso device (flash or run in RAM as appropriate), you will need to use FreeCalypso host tools.
