MTK为MediaTek公司提供的GSM软件方案。

它包含5个部分：

－》L1协议

－》设备驱动

－》协议栈

－》MMI

－》WAP应用

MediaTek为用户提供3个工具：

－》Catcher

2．如何编译

参考文档：

wcr-MTK_MakeBuild_Design_Customer_040930.pdf

－》编译环境

操作系统：

Windows2000,WinXP.推荐Windows2000withSP2orlater.

编译器：

ADS（ArmDeveloperSuite）v1.2.

Perl解析：

ActivePerl.推荐使用ActivePerl5.6.1版本

－》make.bat

Itwillparsecommandlinetodetermineprojectname,platform,andaction.Meanwhile,checking\makedirectoryexistornotandcheckingcommandlineargumentislegalornot.Afterchecking,toexecutebuildscriptGSM2.makbuildscripttoperformaction.

使用：

Usage:

custom=Monza

project=GPRS（GSMonly）

action=new（clean,scan,compile,link）（default）

=update（scan,compile,link）

=remake（compile,link）

=clean（clean）

module=componentmodulename（nucleus,l1,...）

2.addafolder“mcu\make\xyz”forxyz.lis,xyz.inc,xyz.pth,xyz.def.

－》编译生成的文件以及log

1．编译的log在目录C:

\code_100\build\a100中的MT6218B.log。

目录C:

\code_100\build\a100\log下的log文件为各个模块编译时生成的log。

2．编译生成的bin为C:

\code_100\build\a100下的a100_PCB01_gprs_MT6218B_FN.W05_12.bin。

3．编译生成的目标文件在C:

\code_100\build\a100\gprs\MT6218Bo目录中。

3．开发目录结构解析
