hello reem.othman,
could you please share the logs of kernel initialization, for instance, did you see any probing related messages for OV9782?
please see-also Topic 252259, comment #19 for code snippets to revise the symbol of NVCSI
besides, since it’s a global shutter camera, could you please try adding set_mode_delay_ms device tree property to configure maximum wait time for the first frame after capture starts.
