Hello, We have a similar need and would like to connect an ADV7280A-M to a Radxa Rock 5B board. We modified the kernel with the BSP to enable the ADV7180 module and created the DTS overlay below. It is correctly added to the overlays using rsetup , and the driver is properly initialized. The MIPI-CSI signals are indeed being sent, as I forced the FREERUN mode with color bars at 576i. However, I can’t get video output because I encounter an error from the rkcif driver saying it requires a sensor-type input. Do you have a solution for this issue to get video on /dev/video0 ?
