My nvidia platform is Xavier. My GMSL ic chip is max9286-max96705, sensor is ar0231.
I want to capture from four ar0231 in one max9286 simultaneously.Now I can capture from any one of the four cameras, but I can not capture from four cameras simultaneously.I got JetPack4.2 had supportted virtual channel. And someone has capture from 2 cameras simultaneously in TX2 through virtual channel.I discribe the device-tree like it. But I can not capture from any camera. Maybe my device-tree is wrong.Follow is my device-tree
