I am developing a program for Linux that runs on a custam board based on mx53 QSB.

This program is a program that outputs video that captured from the camera from the TVE to TV.

And now, this program is almost finished.



However, there is a problem with the TVE.

Signal output is cut off after 10 minutes the program is running.



To cope with the problem, I'm running the following command in the program.


system (""echo 0> / sys/class/graphics/fb0/blank"");


when Program runs the this command, signal is output again from TVE.


but,  the following error will occur on the console.


mxc_ipu mxc_ipu: Channel already disabled 9
mxc_ipu mxc_ipu: Channel already uninitialized 9
mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x00100000
mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_5 = 0x08800000


furthermore, this way occur time that signal is not output from TVE.



I want to output signal from TVE permanently.

Could you tell me the advice, or a good way?
