Maxim Des chip output 1x4 csi lane to xavier preview wrong

My hardware is max96712 connected to xavier. Max96712 output is 1x4, muxed four cameras from four max9295. Our I2C is OK. When enter preview command, only one picture appeared on the screen and then stopped preview.
Are there any special configurations that I should pay attention to when using virtual channel and camera mux? Do you have xavier configuration file for max96712 output 1x4 csi lane? If the xavier csi clk frequency should raise up when the xavier receive 1X4 csi lane?

Thanks

I would suggest consult with vendor to confirm the configure. Also current only have imx390 as virtual channel reference.
