Hi, LiQiang

      At present, we encounter the problem of using MIPI camera with imx6. Sometimes when the external signal is unstable, the phenomenon of video scrolling occurs, as follows.

      We use the following registers to determine whether the current MIPI signals have errors, but the accuracy is not very high.

       we modify the csi interrupt function csi_enc_callback(int irq, void *dev_id) at drivers/media/video/mxc/capture/ipu_csi_enc.c, try to skip error frame here.


      It's not work perfect.

      We judge by the interval between frames.

      Still not work well.


  Is there any other way to lose the error frames?
