Re: is anyone working on the evdm6437 (davinci dsp)? video capture project help needed please!

hi there... I'm new in the dsp world and I have a project to develop on a evmdm6437 evaluation board (with the ti davinci dm6437 dsp). The idea is to capture the video signal from a pal camera, to store the video frames on the ddr memory and process them with an algorithm (that I already have!). The out put should be the position (x,y) of some particular features in the images. I need the SIMPLEST way to program the dsp to capture the signal and store the frames in the memory. Actually i'm modifying an example code (videoloopback) but i have problems in configuring the video front end and back end registers.
>So..if someone of you is expert in using this evaluation board or programming this dsp please help me! thank you for everything

Hi I need some similar. 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!
