I have the ADV734xEBZ board and I tried to obtain the self-generated SD Color Bar from ADV7341 using the clock at 27 Mhz generated from the ADV7403.
I have followed these step:
- Power-up the board;
- Launch the ATV Benchtop software;
- Select the ADV7403_ADV7180_ADV7341-ver.1.0.txt register program configuration file;
- Run the "525i YPrPb In 4x1 20-bit 422 Out (HS and VS timing)" SD script for ADV7403;
- Write on ADV7341 the following data:
So, the Colorbar not appears in the monitor that shows instead a green noise. What is the matter?
I have misured with an oscilloscope that ADV7403 generates a 27 MHz clock.
Furthermore, I have done the same test with the script for the HD and I have correctly visualized the hatch pattern.
