I'm using TI's TVP5158, which is in debugging
The following problem: set to CH1, A/D, VO_A to output the D1 signal of 8BIT,
But the latter is not recognized. What is the reason and what should I do next?Thank you very much!

What registers are you setting?
Are you saying the clock and data outputs do not wiggle?

Hello!At the bottom are the register Settings for TVP5158, working patterns
It is the analog CVBS input channel 1, the PAL signal, the output select DVO_1,
The format is 8BIT DI format, but the latter is not recognized by the conversion chip.
The standard DI signal is received and the chip input port is normal。
Register setting:
Signal link:
CVBS IN ----- TVP5158 -----FPGA -----GS2972
1.The current state:
Set TVP5158 to a single mode and the output signal cannot be detected by GS2972.
TVP5158 output clock: 27M;
TVP5158's DVD_A output data entered the FPGA extraction HS.
But when you get rid of the input CVBS, the HS, VS, and OE are normal;
Other tests: the FPGA generates the color bar test chart with the 27M clock output of TVP5158, which is detected by the GS2972.
The output is displayed normally.

TVP5158 set content:
Output TVP5158's own blue field test signal at DVD_A.
Format: 8BITS D1 format.PAL system.
The TVP5158 register is as follows:

Enter the CVBS (PAL color bar) at VIN_1
The register is the same as the previous one, but A9:40.
