Using the Sysgen Capture Tool 宋氏電電流電壓表

1. From a command prompt, in your OS design directory, create two subdirectories for the driver. One is for a library corresponding to your driver and the other is for your driver's binary file, which can be a DLL or EXE. （建立src文件夾的copy，改名為DLL,一個(gè)生成lib，另一個(gè)生成DLL,在ep93xx\src\Drivers下面建立目錄dm9isa,然后在下面建立子目錄LIB和DLL）

For example, to customize Com16550.dll, create a subdirectory named %_TARGETPLATROOT%\Drivers\Com16550\Src for the library and %_TARGETPLATROOT%\Drivers\Com16550\DLL for the binary file.

Note   If you were customizing an executable such as Etcha.exe, then you might create %_TARGETPLATROOT%\Apps\Etcha\Src and %_TARGETPLATROOT%\Apps\Etcha\EXE.

2. Verify that the library name for your driver module is different from the name for your driver's binary file. （TARGETNAME從dm9isa要更名為dm9isa_lib）

In this example, Com16550.dll is built by linking Com16550_lib.lib. Most DLL Sysgen targets use the *_lib.lib naming convention because if you do not differentiate the library file and binary file names, the driver's import library has the same name as the static library containing its code. This may result in build problems that are difficult to diagnose accurately.

3. Copy the Public directory that contains code for the module that you want to build into the Src directory that you created. In this example, you would copy the files from Public\Common\OAK\Drivers\Serial\Com16550\*.*. (COPY DM9ISA的源碼到ep93xx\src\Drivers\dm9isa\LIB和ep93xx\src\Drivers\dm9isa\DLL)
4. Navigate to the %_TARGETPLATROOT%\Drivers\Com16550\Src directory. Use a text editor to open the Sources file, and then add the following line.

RELEASETYPE=PLATFORM(在SOURCES文件中增加RELEASETYPE=PLATFORM，這樣BUILD之后的LIB文件就會(huì)生成到PLATFORM\EP93XX\LIB下面

不然原本會(huì)生成到PROJECT目錄的\OAK\LIB下面下面)

If a RELEASETYPE line already exists in the Sources file, then change its value to PLATFORM. This tells the build system that output files should be placed in your OS design's Lib or target directories.

5. Verify that the following line appears in the Sources file, and then save the file and close the text editor.

WINCEOEM=1(Sources文件中添加WINCEOEM=1,去掉WINCETARGETFILE0=$(_COMMONOAKROOT)\lib\$(_CPUINDPATH)\dm9isa.def)

This tells the build system to include portions of header files that are only available to OEMs who are building run-time images.

6. Build the library in %_TARGETPLATROOT%\Drivers\Com16550\Src. If there are any errors, resolve them before proceeding. A successful build creates and places the file Com16550_lib.lib in the appropriate subdirectory of %_TARGETPLATROOT%\lib. （BUILD –C生成LIB到PLATFORM\EP93XX\LIB\dm9isa_lib.lib）
7. Navigate to the directory for your driver's binary file. For example, navigate to %_TARGETPLATROOT%\Drivers\Com16550\DLL. (切換目錄到ep93xx\src\Drivers\dm9isa\DLL)
8. Run Sysgen_capture with the usual Sysgen parameters. For example, type the following line to execute Sysgen_capture with Com16550 as a target.

Sysgen_capture com16550（執(zhí)行SYSGEN_CAPTURE DM9ISA，生成souces.DM9ISA）系統(tǒng)會(huì)去抓系統(tǒng)MAKEFILE.DEF中模塊的一些信息

This creates one or more files, one of which is a Sources file with the name of the driver as the file extension. For example, a file created using Com16550 as a target would be named Sources.com16550. The Sysgen_capture.bat utility creates one such file for each .dll or .exe target created while running your Sysgen command.

9. Rename the sources file for your driver as Sources. For example, remove the extension .com16550 from the file name Sources.com16550. (把souces.DM9ISA更名為sources)
10. Copy one of the selected module's sample Makefiles into your Src directory. At a minimum, you need a Sources file and a Makefile to run Build.exe. (把LIB中的Makefiles拷貝到DLL中)

For example, copy the Makefile located in %_TARGETPLATROOT%\Drivers\Com16550\Src into %_TARGETPLATROOT%\Drivers\Com16550\DLL.

11. Run Build.exe. This creates the same binary as the standard Sysgen command, and places it in your OS design's target directory, which is a subdirectory of %_TARGETPLATROOT%\target. Examine Build.log to determine where the binary was created. （在ep93xx\src\Drivers\dm9isa\DLL中，BUILD -C）

Note   This version of the driver uses the standard version of Com16550_lib.lib, not the version that you created in %_TARGETPLATROOT%\Drivers\Com16550\src.

12. In %_TARGETPLATROOT%\Drivers\Com16550\Src, open the sources file in a text editor. Remove the TARGETLIBS, or SOURCELIBS, entry for Com16550_lib.lib, and move it to SOURCELIBS, changing the path as appropriate. You may need to replace occurrences of %_PUBLICROOT%\common\oak with %_TARGETPLATROOT%. (把$(_PUBLICROOT)\common\oak\lib\$(_CPUINDPATH)\dm9isa.lib \改為$(_TARGETPLATROOT)\lib\$(_CPUINDPATH)\dm9isa_lib.lib，即鏈接本地的LIB)
13. Navigate to the directory for your driver's binary file, for example, %_TARGETPLATROOT%\Drivers\Com16550\DLL, and then run Build.exe. Build.exe builds the target binary using your version of Com16550_lib.lib, which you can confirm by examining Build.log. (鏈接你自己生成的LIB之后（ep93xx\src\drivers\lib\ dm9isa_lib.lib,DM9ISA的DLL編譯，完全本地化）

Note   In order to delete all the object files, you may need to run Build.exe with the –c parameter.

14. In the %_TARGETPLATROOT%\Drivers\Com16550 directory, create a Dirs file that lists, in order, the Src and DLL, or EXE, directories. This enables you to build your modified version of %_TARGETPLATROOT%\Drivers\Com16550\Src and link an executable with one build command. （在ep93xx\src\drivers\dm9isa目錄下創(chuàng)建dirs文件，添加LIB和DLL，注意順序，先編譯LIB,然后生成DLL）
15. Run Build.exe with the –c option in the %_PROJECTROOT%\CustomDriver directory and confirm that the contents of both the Src and DLL, or EXE, subdirectories are built, and that the driver links successfully. (在ep93xx\src\drivers\dm9isa運(yùn)行BUILD –C即可在本地BSP編譯鏈接，生成DM9ISA.DLL文件，不用SYSGEN整個(gè)系統(tǒng)，且避免影響其他平臺(tái)。)
