no ipu interrupts sometimes

Hi,

 

Our coustom board is based on i.mx53 & we are using linux 2.6.35.

We are using mxc_v4l2_overlay.out application to capture & display.

Everything works fine, but sometimes there is no data on display.

 

We found that when there is no data on display, there is no ipu interrupt generated.

In working/non-working case, the code flow is same & there is no error.

 

I am not sure why the ipu interrupt is not getting generated sometimes?

 

Please help us to understand the problem.

 

Thanks,

Praveen
