Hi @ all

I use the IMX.6QDL on an DartMX6 Board from Varicite. I would like to use an MIPI CMOS Gray scale Senor (IMX290). I have running an other Sensor on Virtual Chanel 1. It works without problems. But it is Impossible to change the Virtual Chanel from the IMX290. So i have to use the Virtual Chanel 0. Now i got problems if i change the virtual Chanel of the old Sensor to 0 and the new sensor will not work too. See Attach. If I darken the sensor the image will also darken. So the data comes from the sensor. But I don't get a stable picture.

Both sensors use MIPI with 4Lanes, a data rate of 594Mbps and the data format RAW10. I can't find the differences between VC0 and VC1.

VC0 = > MUX Parallel => IPU0 CSI0 => SMFC => IDMAC => Memory

VC1 => IPU0 CSI1 => SMFC => IDMAC => Memory

I can't find the Problem. can anyone help me?
