Speed problem Mini2440 + 3.5 LCD

Hi all,

I have a strange problem with my mini2400. I have an application that get a
number of 100 frames from USB camera. After 4-5 executions my application
works slower. At the first run, my application can get the frames with a
speed around of 20fps. After 4-5 executions the speed is around of 10fps
and my mini2440 works slower. What's happen ?

I think  there is a problem with gspa driver. Area of SDRAM and CPU is
warm. Maybe CPU needs more power and LCD consuption is too big.

Thanks a lot !

How can you be sure it's not a bug in your application?

I think it's impossible to be a bug in my application. My application has
just few line of code using OpenCV. Why it works great at began ? and after
4-5 execution it works slowly. After this I open USB camera demo
application and it works slowly too.

I think it's a problem with gspa driver.
