Hi,
we used the video port connect directly to a TTL-LCD interface using DE, RGB888 interface, but sometimes the LCD screen will black out randomly, it happens for few times and randomly but really happens. Most of the time it works fine. And we checked the hardware interface and found the RGB888 data goes to 0, but the DE, CLK signal are still correct. We tried to restart the VPSS by scripts, but failed.
I would like to ask what we should do to find the bug, does anyone have such experience?
Thanks, Karl
