Hello TI,

We want to profile CPU usage of DM814x. Please let me know if any tool available to check the same thing.

Thanks,

Hello,

What is the software release that you are using here?
You could check this guide:
processors.wiki.ti.com/.../TI81XX_PSP_04.04.00.02_Feature_Performance_Guide

Is this what you are looking for?

Thank you Margarita,

I will check this. we are using EZSDK 5.02 with overlay code. Basically I want to debug VIP reset issue because when CPU load is more or increase then I see this VIP reset issue on dm814x. This reset drop around 30 frames, So we want that this issue must not generated or reproduced.

Thanks,

Hello,

It seems that the reset is observed when there is a overflow.
In HDVPSS there is a capture demo. You could check the capture component itself.

You could check these threads also:

Hope this helps.
