－》WAP
??? 如何編譯
??? 參考文檔：wcr-MTK_MakeBuild_Design_Customer_040930.pdf

－》編譯環境
??? 操作系統：Windows 2000, WinXP. 推薦Windows 2000 with SP2 or later.
??? 編譯器：ADS (Arm Developer Suite) v1.2.
??? Perl解析：ActivePerl.推薦使用ActivePerl 5.6.1版本

－》make.bat
??? It will parse command line to determine project name, platform, and action. Meanwhile, checking /make directory exist or not and checking command line argument is legal or not. After checking, to execute build script GSM2.mak build script to perform action.
使用：
Usage: Make [custom=customername] <project> <platform> <action> [module]"
custom = Monza
project = GPRS (GSM only)
action = new (clean, scan, compile, link) (default)
= update (scan, compile, link)
= remake (compile, link)
= clean (clean)
module = component module name (nucleus, l1, ...)

Example:
To make/build new GPRS project, clean all old objects, libraries, and log files etc., the new action also creates necessary directories and removes all temporary files, and flushes log files automatically.
d:>/pvcs/maui/mcu/Make custom=Monza GPRS new
To update project dependency, and compile changed modules, link. Notice that, update and remake action won’t remove temporary files, and flush log file. Build results will be append after last log file.
d:>/pvcs/maui/mcu/Make custom=Monza GPRS update
To recompile changed files, and link
d:>/pvcs/maui/mcu/Make custom=Monza GPRS remake
To clean all objects, temporary files, libraries, and executable binaries. Meanwhile log file will also be flushed.
d:>/pvcs/maui/mcu/Make custom=Monza GPRS clean
To clean dedicated init modules’ objects libraries. Meanwhile log file will also be flushed.
d:>/pvcs/maui/mcu/Make custom=Monza GPRS clean init

－》how to customize your build environment
?！！！To add some modules into or remove some modules from the building procedure.
To complete this kind of configuration, it is necessary to understand the following variables in the make file
Monza_GPRS.mak
?? COMPLIST: list all source code modules can be built to .lib. In initial custom release, COMPLIST
should be the sum of CUS_REL_SRC_COMP and CUS_REL_PAR_SRC_COMP. The following is the initial setting in custom release.
ifeq ($(strip $(CUSTOM_RELEASE)),TRUE)
COMPLIST = $(strip $(CUS_REL_SRC_COMP))
COMPLIST += $(strip $(CUS_REL_PAR_SRC_COMP))
endif
?? CUS_REL_MTK_COMP: list all modules provided with .lib only. These .lib are put in /mcu/mtk_libs.
?? If you want to add a source module
??? 1、add the module "xyz" (in lower case) into COMPLIST.
ifeq ($(strip $(CUSTOM_RELEASE)),TRUE)
COMPLIST = $(strip $(CUS_REL_SRC_COMP))
COMPLIST += $(strip $(CUS_REL_PAR_SRC_COMP))
COMPLIST += xyz
endif
??? 2、add a folder “mcu/make/xyz” for xyz.lis, xyz.inc, xyz.pth, xyz.def.

－》編譯生成的文件以及log
??? 1．編譯的log在目錄C:/code_100/build/a100中的MT6218B.log。目錄C:/code_100/build/a100/log下的log文件為各個模塊編譯時生成的log。
??? 2．編譯生成的bin為C:/code_100/build/a100下的a100_PCB01_gprs_MT6218B_FN.W05_12.bin。
??? 3．編譯生成的目標文件在C:/code_100/build/a100/gprs/MT6218Bo目錄中。

??? 3、開發目錄結構解析
參考文檔：wcr-MTK_MakeBuild_Design_Customer_040930.pdf
目錄結構：

4．開發工具的了解
參考目錄《工具》中的文件。
?? 工具：
－》Catcher
Catcher is a PC-side tool for MTK GSM/GPRS Products. The main purpose of Catcher is for logging primitives and debug information. Engineers can use Catcher to analyze the behavior of mobile phones.

－》META
META (Mobile Engineering Testing Architecture) is designed to provide the functionality of RF testing, NVRAM access testing, speech related testing of advanced feature – melody and voice memo.

－》MCT
UI制作工具，包括菜單制作，圖片制作，字體制作等等。

5．程序入口，程序導讀

－》MMI任務入口：
C:/code_100/plutommi/mmi/Framework/Tasks/TasksSrc
中文件MMITask.c函數MMI_task。

－》MMI任務的建立：
C:/code_100/plutommi/mmi/Framework/Osl/OslSrc
中文件pixtelMMI.c函數WinMain調用InitApplication函數，在該函數中建立MMI任務，建立任務的接口函數為：osl_create_task。

－》MMI任務信息：
?{"MMI TASK"（任務名稱）, "MMI Q"（隊列名稱）， 127（優先級）， 4096（堆棧大小），MAX_PRT_NODES（隊列結點個數）， MMI_task（任務入口）}。

－》MMI模塊入口：
目錄C:/code_100/plutommi/mmi中為MMI各個模塊的代碼。比如鬧鐘模塊，源代碼在C:/code_100/plutommi/mmi/Alarm/AlarmSrc中，頭文件在C:/code_100/plutommi/mmi/Alarm/AlarmInc中。首先找到初始化鬧鐘的函數AlmInit，該函數定義在選擇鬧鐘菜單項時調用函數HighlightAlmMenu進入鬧鐘功能。

6．MMI的制作
參考文檔：

文件名
?文件內容描述
?
API For Writing Applications Using Pixtel MMI Platform.pdf
?各類窗口列表
?
Writing Applications Using Pixtel MMI Platform.pdf
?如何寫應用程序
?

MMI 2.0 Design DOC和MMI Design Doc目錄中對MMI中的各個模塊進行描述，因此在研究某一模塊時可以在這兩個文件夾中找到該模塊的介紹，通過這些文檔可以加速對該模塊編碼的理解。
MMI的模塊在路徑C:/code_100/plutommi中。
－》設計一個應用程序的流程如下： -
??? 1. Write an Initialization function to register the various event handlers.
??? 2. Write a populate function to register various string and image elements for the
application.
??? 3. Write highlight handlers for function registered.菜單項的功能，當用戶選擇菜單項后執行的函數。
??? 4. Write the Entry functions。入口函數
??? 5. Write the Exit function。出口函數
??? 6. Write the business logic to call between various entry functions.
