ADV7611 with TP2915

Hi,

  Please check on your SoC side whether it has been configured properly according to the output signals from the ADV7611, as there seem to be no issues with the ADV7611 output pins.

Thanks,

Poornima

Hi Poornima,

Thanks for the respones. Following are obersertvations

IO MAP(0x98) 0x6B gives 0x00 - 

HDMI MAP(0x68) 0x05 gives 0x30 - DVI mode

Also, what are the commands to load the internal EDID of ADV7611 based on the resolution?

Hi,

  Please refer this thread to load internal EDID on ADV7611 How can I use ADV7611 with an internal EDID - Q&A - Video - EngineerZone

Thanks,

Hi Poornima,

Thanks, for the updates. 

Could you please guide me to set the resolution of 640x480 or 720x480 interlaced/progressive resolution? 

what are the steps involved in configuring ADV7611? Also, is there any option to generate test pattern from ADV7611?

Hi,

Also, is there any option to generate test pattern from ADV7611?

  Not test pattern but we can enable free run mode in ADV7611 and It provides the user with a stable clock and predictable data if the input signal cannot be decoded, for example, if input video is not present. It controls default color insertion and causes the ADV7611 to generate a default clock.

  Please refer below snap for reference.

Also use EDID editor tool for enabling the particular resolution .

Thanks,

Poornima

Hi,

Where can i find the EDID for 1280x720p/i resolution? 

Below link shows a .dat file which can edit the EDID, is there any user manual document related to .dat file?

Hi,

Is there any EDID script from AD for the below resolutions

1. 1280x720p/i
2. 1920x1080p/i
3. 800x600p/i

Hi,

  Please crosscheck your configuration with your respective formats at ez.analog.com/.../1817.ADV7611_2D00_VER.3.0c.txt.zip

Thanks,

Hi Poornima,

Thank you for the support provided so far.

We are still in the process of evaluating how best to use this device in our project. Our initial approach was to use the TP2915 evaluation board to stream video from HDMI to analog (HDMI → ADV7611 → TP2915 → analog display).
With this approach, we have tried multiple configurations, but unfortunately without success.
Given this, we would like to restart the evaluation with your guidance and support.
As discussed, our next step is to enable free‑run mode on the ADV7611, preferably with a custom solid color (other than the default blue). Successfully achieving this will give us confidence that the hardware path—from ADV7611 to TP2915 and finally to the display—is functioning correctly.

For your reference, we are using the TP2915 Evaluation Board, and the document “TP2915 Evaluation Board Manual R11.pdf” is attached in case it is helpful to understand the hardware setup we are working with.

Could you please guide us with the required register settings for both ADV7611 and TP2915 to enable free‑run mode with a custom color output?

We are also open to considering any alternative solution or approach that fits our requirements. We would really appreciate your support in all possible ways to help us get this interface working.

This evaluation is critical for us, as successfully demonstrating this interface will help us move forward with a new customer who has strong potential for future business.

Looking forward to your guidance.

Best regards,
Arief Raja
