Other Parts Discussed in Thread: OMAP3530

  Hey! I have a boad called devkit8000 which is Similar to TI_EVM.I want ro run the dsp of omap3530.I have followed the article "Getting Started Guide for OMAP35xx DVSDK WinCE 100.pdf" to setup dvsdk on my PC and compile the project DVSDK with TI_EVM_3530_BSP. As a result,in the release director, there are the neccessary files. Such as NK.bin, EbootSD.nb0, MLO, dsplinkk.dll , H264decoder.dll and so on.Then I copy these Image to SDcard , boot my system and run the application video_decode_io2_omap3530.exe. The command line is as follows:

video_decode_io2_omap3530 -c h264dec -i davincieffect_ntsc.264 -o davincieffect_ntsc.264.yuv -n 50

and the result infomation is as follows:

______________________________

Starting application...

Failded to Create loader

End of application.

______________________________

Can you tell me what's wrong with my operation, how can I run the Demo correctly? Any thanks!

    Yuantai,

    Where is the input file located? Could you try the command by providing the absolute path for the input and output files? If they are located in storage card, for example, then "-i \"storage card"\davincieffect..." depending on how the root for your SD card in the application.

    Thanks,

    Aparna

    Aparna Balasubramanian,

    Thanks for you reply! For Example,I copy the files davincieffect_ntsc.264 and video_decode_io2_omap3530.exe to the SD card.

    And my command is as follows:

    ------------------------------------------------------------------

    \> cd \Storage Card

    \Storage Card> video_decode_io2_omap3530 -c h264dec -i davincieffect_ntsc.264 -o davincieffect_ntsc.264.yuv -n 50

    Starting application ...

    Failed to Create loader

    End of application.

    ------------------------------------------------------------------

    In addition,what puzzles me is that when use this command under the "\"path,this command will fail.

    For example,

    ------------------------------------------------------------------

    \> \Storage Card\video_decode_io2_omap3530 -c h264dec -i \Storage Card\davincieffect_ntsc.264 -o \Storage Card\davincieffect_ntsc.264.yuv -n 50

    \ Storage: File not found.

    ------------------------------------------------------------------

    I don't know what's wrong with my operation.Did I ignore something?

    Thanks!

    Yuantai,

    Could you enclose the Storage Card in the path for file between double quotes ("Storage Card")? That should take care of the problem.

    Regards,

    Aparna

    Aparna,

    Thanks for you suggestion.The last problem is esayly to solve now.But the main problem hasn't sloved.I could run the application,but can not have a correct result.It is still said

    "

    Starting application ...

    Failed to Create loader

    End of application

    ".

    Have you missed the problem. How can I run the application correctly. Why did it Fail to Create loader.

    In addition,I have read the article " InstallGuide_WinCE_omap3530.pdf" and run the samples of dsplinik correctly.

    That means my board can run arm and link dsp correctly! But it is not the same result of the DVSDK demo.

    Thanks,

    yuantai

    Can you post the latest command line you are using to run the test. One of the primary reasons for the error you see is that it is still not able to find the input file (there are other reasons as well).

    Apart from the earlier post, to get a more detailed debug trace follow the steps mentioned under the WinCE section in this wiki article http://processors.wiki.ti.com/index.php/CE_DEBUG . This should give more information on the error you are seeing.

    (Please note that you will have to search for the utility since the path mentioned is relative to where you installed the DVSDK.)
