AM572x openCV application

Please let me know if more information is required . I shall provide you the same.

Please post the build log.

Hi ,

Thanks for coming.

Please find the enclosed logs and Makfile which I am using.

Can please somebody help me in compiling this simple OpenCV application?

Thanks for your time in going through this issue.

Thanks and Regards,

Hi,

If anybody can share me an example makefile to how to compile Open CV application on linux SDK for TI AM 572X processor. That would also be great for me.

Thanks,
Mohit

Thanks. I have asked the software team to look at this. They will respond here.

Hi Margarita,

Thanks for the document.

I am able to get useful information from this document and solve my problem.

Thanks and Regards,
Mohit
