C6678 MCSDK_VIDEO视频演示例子不能正确输出

 

 

如上图所示不能完全按照文档的描述输出,只有最上面4个,其他的没有。 DSP没有正确输出。

请问这是什么问题呢?

anqiang ren1:

有谁用过这个例子吗?  麻烦帮我看看~!

Allen35065:

是否是WINXP系统?请关闭所有防火墙试试,有些防火墙会阻止数据流进出

我的电脑没有防火墙,不用上网,是裸系统。。

请使用WINXP系统进行测试,按照以下步骤,step 1&2 不用做,在TFTP里确认EVM已下载全部文件,sv01的大小为21,991,575 bytes,请确认使用文件与其一致

Using sv01 as one example, the build command make sv01 will produce directory: <MCSDK Video/Audio Install Dir>\dsp\mkrel\sv01 with the following files: sv01.out, sv01.map, readme_sv01.txt.1. If a source debugger requires all source files to be combined into a single directory, "FLAT=YES" may be added in the make command line, which will create the directory mkrel\sv01\flat  containing all source and header files used for the build. 2. After making the first build, if there is no source file change in \components directory, "RTSCBYPASS=YES" may be added in the make command line, which will bypass compiling the  components. If there is no source file change in dsp\ggcfg\build\hdg\sv01\bios directory, "BIOSCFGPKGBYPASS=YES" may be added in the make command line, which will bypass compiling the  BIOS configuration package.3. Flash IBL using tools in C:\Program Files\Texas Instruments\mcsdk_video_2_0_0_9\demos\demoutils\IBL_flash4. Set to TFTP boot (Dips according to http://processors.wiki.ti.com/index.php/TMDXEVM6678L_EVM_Hardware_Setup)5. Set PC ip to 192.168.0.102, connect PC and EVM by ethernet.6. Start TFTP server on PC.7. Power on EVM to test if PC and EVM are configured currectly in TFTP log.8. Use ipconfig /all to get MAC address 5C-26-0A-68-F0-3A. Use windump to get network device ID \Device\NPF_{20F40BEA-DAE7-4297-B226-E001AD67CA0F}.9. Run genDemo.bat config.txt to generate demo image and stream files. genDemo.bat config.txt10. Start TFTP, the directory should include sv01.out.11. Power on EVM and download sv01 from PC.12. Run sendpackets and startMplayers in C:\Program Files\Texas Instruments\mcsdk_video_2_0_0_9\demos\demoroot\Reference\utils\bin

我是这样做的。。你看我贴的图片。我的sv01的大小比21,991,575 bytes稍微小一点,但我的方法是一样的。

Allen35065:

我贴了我用的.out,在我的PC测试通过,你可以试试

回复 Allen35065:

用这个还是有问题,只出现4个界面,抓包发现6678没有往外给PC回应,不知道是哪里问题呀

lei wang2:

您好,我现在在做这个例子,但是运行startMplayer.bat就会

我用的WIN7系统,所有的东西都装在D盘(系统盘)。能否给予知道,谢谢!

Ping Li3:

回复 lei wang2:

你这个是因为mplayer的位置不正确造成的,重新安装一下,将位置放在c:/Program files/MPlayer For Windows/mplayer

回复 Allen35065:

你好,sv01.out编译出来都是21,991,575 字节吗?还是依赖于MCSDK VIDEO等版本,编译出来大小不是一样的?
