BIOS and PSP problems in my EVM6437

Pablo Varela

Hi.

I got EVM6437 with CCS3.3.38.2 and BIOS5.31

I need processing video from one camera and give it in output DAC. I found "Accessing_Pixels_In_A_Frame_1_03"  based in "video_preview" doing that, but I can't debug.  I recompile "video_preview" and there's no troubles, I load it and it runs (CCS tells me "running"), but I can't  "go to main", stopping in breakpoints (SW/HW). I see video camera in output,  but I think the program loaded in flash (default program) is executing and not RAM downloaded program ...

I have a lot of problems with every projects using BIOS/PSP. I can't debug this projects, and I have doubts programs are executing correctly. Only test examples(included in CCS/boards/DM6437 folder) work (videoloopbak included!).

I followed steps in "C6000 Embedded Design Workshop Using BIOS" (all files downloaded) and I could create a project with BIOS to process audio-in and give it on output. In this case, I can debug. I understand GUI and utilities/tools. But in this workshop uses audio decoder only (AIC33 Codec) and not video decoder (TVP5142M2)

I think examples/samples in dm6437 folder (dvsdk_1_01_00_15) doesn't work. PSP examples in same folder don't work too.

How can I resolve this problems!! have anyone programs/tutorial to doing video processing with BIOS/PSP??

Thanks a lot!

    Pablo,

    Please mention the BIOS PSP version being used?

    Please go through the userguide, to understand and to know the any special requirement for a specific application.

    Open the required project, then once after loading the executable, please press Ctrl + M to go to the main() ( can also be selected from Debug->Go Main). From here, open the required file from the project and put breakpoint accordingly.

    Let me know the result and your comments.

    Thanks and Regards,

    Thanks.

    it's strange: I use dvsdk_1_01_00_15, installed with CDs attached with Digital Spectrum package. If I check all projects included in this folder (examples, PSP examples and dm6437_demo_1_30_00), they doesn't work (I can compile it). I check it making ctrl+M (go to main) or including breakpoints. Never reaches it.

    I don't know what to do. I attach SW information:

    (from help/about CCS info):

    • CCS 3.3.38.2
    • integrated development  5.98.0.219
    • BIOS 5.31.07
    • Code Generation Tools v6.0.8
    • Board revision 00.00.84
    • Target Silicon Revision 00.00.02

    From dvsdk_1_01_00_15 folder I check psp is psp_1_00_02_00

    I am blocked in my training before development, and is urgent resolve this problems...

    Please, help me.

    Thanks a lot

    I found the solution thanks to  "Sankaranarayanan B" in DSPRelated Forum I resolved my problems: I should changing GEL file, downloaded from Digital Spectrum web, and then, all projects ran fine.

    Thanks a lot!
