@Oskar_Enoksson yes I verified that capturing the native raw data works fine for me as well, but the connection to the ISP is simply not there, so the /dev/v4l-subdev4 is not there…
@avaf I’m on the NanoPC-T6 actually, but it is exactly the same problem that Oskar has described… my setup is just either one single 4-lane OV4689 on csi0, or two 4-lane OV4689 on csi0 and csi1 - DeviceTree works on 5.10.160 fine, does not on 6.1.99
