Hello

 

 

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?
