hello busch.johannes,
yes, there’re error reported by PHY_INTR0, you may also check TRM for NVCSI_PHY_0_CILA_INTR_0_MASK_CILA_0.
furthermore,
SOT_SB: it means there’s one bit error detected on the data-lane sync word
SOT_MB: it means more than one bit error has detected on the data-lane sync word.
in my experience, this usually due to sensor side did not output frames correctly.
please also review your pixel clock settings,
FYI, I usually use below formula to calculate sensor pixel clock for sensor bring-up.
pixel_clk_hz = sensor data rate per lane (Mbps) * number of lanes / bits per pixel
besides, here’s see-also Topic 260685 for your reference.
