Dear freescale,

We used imx6d for our production. We have one camera through the analog signal input(cvbs) to video decoder(tw8834), and then output bt656 data to ipu.

We do pressure test for camera,  we kept switching in the main interface and reverse interface for one night. There is a great chance can't get reverse image,

and reverse interface is black.

 

Log is as follows:

[10:39:49]root@b1021h:/ # [ 1700.285412] imx-ipuv3 imx-ipuv3.1: IPU Warning - IPU_INT_STAT_5 = 0x00800000
