Part Number: PROCESSOR-SDK-DRA8X-TDA4X
We have recently upgraded to psdk v7 from v6.02. We have noticed that for the fixed 2A config, although the RAW image is verified to be same, the YUV images are different. Attaching the YUV images for v6.02 and v7 below.
Please note that WB gains are applied to sensor in both v6 and v7. Also, we have made sure that dcc xmls and default values for the ISP blocks are same in v7 compared to v6.
It would be really helpful to debug this issue, if you can list out the changes in the ISP config between the v6 and v7 releases.
I am not able to see the attachments. Can you please copy the link here?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Mayank Mangla:
Images are attached. The brighter image is from v7 and darker image is from v6.02.
In reply to RINKU WILSON:
Which image sensor are you using? Are you using default SDK tuning?
We are using AR0233 sensor. Regarding 2A, all the parameters are fixed to same values for both v6 and v7 at sensor driver level. Consequently, we are able to observe same raw image for both versions.
In case of ISP tuning, we copied the tuning xmls we had for v6 to v7 (not the default ones), and made sure the ISP config is same between both versions. However, we are observing this brightness change.
There have been no major changes in ISP configuration. But it is possible that something changed inadvertently Will you be able to dump ISP registers from 6.2 and 7.0?
Yes, we have dumped ISP registers corresponding to different ISP blocks. We have not found any difference except for CCM weights which doesn't explain the brightness difference.
Is there any way we can dump intermediate output in ISP? Or any suggestion to further debug this?
Can you please confirm that you are using the same operating mode (WDR/Linear) for both the versions? Please also check that WDR decompanding settings have not changed.
