Hello,

We are running the application on the custom board having TDA2xx SoC and Vision SDK 3.0.7

The usecase is as below:

Capture -> VPE -> Display_Video

For few minutes initially the display is coming properly. However, after some time the display is not visible and below log messages appear continuously.

    Hi Gaviraju,

    Thanks for the quick response.

    We have been testing entire solution on custom board since long time the evaluation board does not meet all our required features.

    However, based on your suggestion I will remove the integrated code and test the TI code and provide you logs.

    Meanwhile, if you could provide some information on the reason for this kind of log message because after this log statements the entire system is going to out of memory and system stops working. If you could provide reason for this behaviour of vision sdk, I will meanwhile keep debugging....

    Regards,

    Raghavan
