TDA4VM: IMX390 camera pink artifact when using 30 fps mode

Part Number: TDA4VM

Hello,

I'm seeing a problem when I'm trying to use 30fps WDR mode of the IMX390 sensor. Any bright and/or over-saturated areas of the image appear pink color when using the 30fps WDR mode. In the 60fps WDR mode, the color looks white. It's most noticeable in the sky near the sun, but any white objects like cars or signs have the same problem.

I'm using D3RCM-IMX390-953 camera with TI SDK 7.1.  I also tried on 7.3 and same issue happened.

I believe this issue is similar to https://e2e.ti.com/support/processors/f/processors-forum/992746/tda4vm-white-objects-display-as-pink-using-imx390-at-30-fps-uc0.

I capture raw data using the single cam application, the only difference is commenting out the line

sensor_features_enabled |= ISS_SENSOR_FEATURE_CFG_UC1;

to switch to 30fps mode.

60fps raw data

30fps raw data
