Thread Summary

                The user is facing issues with configuring the ADV7842 on a custom board using I2C commands captured from the EVAL-8005 board. The problem is that the captured settings do not produce an output when reconfigured, unlike with the ADV8005. The solution involves using the VisualDSP 5.1.2 environment to modify the source code for the ADV7619 and the I2C address of 0x18, as the EVAL-8005 firmware was designed for API calls and does not support plain scripts. The user encountered build errors after making these changes, and the support team is investigating the issue.

I'm trying to explore the minimum necessary I2C commands needed to configure the 7842 on the EVAL-8005 board.  As a baseline when using AVES Blue if I perform a capture all and then feed those settings back into the 7842 as a script, I don't get any output, even if the ADV8005 is reconfigured.

 
This procedure works with the ADV8005, why does it not seem to work with the 7842?

 
Thanks.

    Since the EVAL-ADV8005-SMZ only has ADV7625 and ADV7842 connected to the ADV8005, I think the VDSP source code project only supports configurations of ADV7625/ADV8005 and ADV7842/ADV8005. I don't think it supports ADV7619/ADV8005.
    
 
    Jeyasudha can provide clarification on this.
