TDA4VM: Problem of AWB tuning in DCC

wang zhili

Part Number: TDA4VM

Hello TI experts,

When I do the calibration and tuning of AWB in DCC of TDA4, I found that the Cr-Cb curve and the interpolated plot for each gray level have no changes after I changed the value of "Tuning radius", do you konw what is the matter?

And I can not see any changes in images after I update the bin file to sensor, so could you help me check that whether the AWB can be updated to the target sensor online or not?

Changing radius only changes the output xml and does not change the plot.

Online update for AWB should be supported as far as I know.
Which version of tuning tool and PSDK do you have?

The version of tuning tool is DCC 02.50, and the SDK version is 7.03.

But there is no change in images of TDA4 after I update the AWB bin file, which is weird. I'll try again.

DCC ITT V2.5 is the latest release, but PSDK 7.03 is about 1.5 years old.
Please make sure you have the correct camera ID.

AWB calibration does not change dynamically and therefore online update for AWB is not really useful anyway.
