Hi.

I set fmt-> width = 400.
However, the capture results did not improve.

How about less than 720/2

25

Hi.

I tried with fmt-> width = 200 and fmt-> width = 360, but the results didn’t improve.

26

The TEGRA_CSI_PIXEL_PARSER_STATUS still show 0x00004015?

27

Yes, It is.

28

Maybe check others errors. Maybe probe the signal make sure it’s follow the MIPI spec.

Thank you for teaching me.
I will look it up.
