Other Parts Discussed in Thread: TMS320DM6437, CCSTUDIO

Hi,i have three TMS320DM6437 video development platforms,two of them have some problems.
Q1.  I can run the demo program correctly which built in platform's memory,(this program can output the video signal on the LCD monitor and the input signal is from CCD camera)but i can't run the demo which was noted in the  TMS320DM6437 DVDP Getting Started Guide section 3.3.
Q2.  when i run the video_preview project,it's seems normal at the beginning,the video output is correct but there should appear a window called "stdout" which near by the "GEL output" and it didn't appear.And when i set the breakpoint in the program,the program should stop at the breakpoint but it didn't stop.      
        those three platform that i have,the version of the normal one which can run the project correctly(means can appears "stdout" window and can stop at the breakpoint) is different then the other two and the two abnormal platforms are the same version.
besides,i have the connect problem with the two abnormal platforms under.

 
Q3.after test many times, the two abnormal platforms can't run the project which in "C:\dvsdk_1_01_00_15\examples" correctly(means can't not stop at the breakpoint),but can runs the project in "C:\CCStudio_v3.3\boards\evmdm6437_v2\tests" (ex.video_colorbars) correctly.why is that?

P.S.  attach the information of the three platforms and the preview project.

    John,

    Are the source code for the two examples under "C:\dvsdk_1_01_00_15\examples" and "evmdm6437_v2\tests" the same? If yes, It is possible that one example is built in the release mode which means the executable doesnot have any debg information due to which you cannot set break points. Can you build the code in Debug mode and try to set the break points at the initialization stage.

    Also can you check if both the examples are using the same GEL file for the device?

    Regards,

    Rahul

    Rahul,

     

    Thank you for response.

     

    first,all of the projects that i test are built in debug mode and the source code of the two project are not the same,they are two different project.

     

    The real problem is there are three platforms,and the version of three platforms are different(one is 702075 REV E and the other two platform's version is 702075-1001 REV I)

     

    when i use those platforms to build and run the example which under "C:\dvsdk_1_01_00_15\examples" , the two platforms which they're version is "702075-1001 REV I" can't not run correctly, and when i set the break point at the source code named "video_preview.c" ,the program won't stop.

     

    However, those problem never happened on the platform which it's version is 702075 REV E.

     

    Thank you for helping me and sorry for my bad English.
