We are trying to get ADV7282AM evaluation board going. We are using DVP Eval software and ADV7282M_CUST scripts to enable colorbar test pattern on the board, however when we try to receive this signal on the raspberry pi 4 there is none. We see that there is a signal on D0N and D0P lanes and something that seems like DC offset on clock lanes (we have 200 MHz oscilloscope, so I assume it is to be expected). We've also noticed that CLKP lane has quite small resistance to ground compared to other lanes - 120 Ohms. Is this normal? Should the board work right away with RPi4 provided there are already drivers and device tree overlays in the kernel? What else could we check?
