Problems of running OpenCV DSP kernels in C6ACCEL

Weilong Chen

The latest EZSDK for DM8168 has included the OpenCV DSP kernels in C6ACCEL. I am able to build and run my application based on C6ACCEL OpenCV but the output results are not correct. Anyone can help? Thanks!

Weilong,

The EZSDK 5.02 is missing some components of the setup required to run the OpenCV sample application. Did you build the ARM side OpenCV library as described here

http://processors.wiki.ti.com/index.php/Building_OpenCV_for_ARM_Cortex-A8 and put it on your target filesystem?

Did you apply the OpenCV patch provided in C6accel? When you run the application, have you disabled the firmware? Can you elaborate what you mean when you say the output results are not correct.

Regards,

Rahul

Hi Rahul

Thanks for your reply.

Yes, I can build OpenCV2.2 for the ARM side and the results are all correct. But I cannot run OpenCV on the DSP through the interface in C6accel. I can only see black image output.

May I know which OpenCV patch in C6accel? What do you mean "disable the firmware"?

Regards,

Weilong
