The camera pathway is: CVBS--->Tcon IC--->BT656-4 output--->i.MX6 IPU block.

Now original setting of CSI is blow. This setting that the gaid line of camera is not continuous.

Hello Xiaoyin,

I consulted i.MX expert on this question. See his reply:

------------------------

Customer should not change the CCIR_CODE_1 and CCIR_CODE_2 setting if the input is standard BT656.

Customer can check the IPU_CSI_OUT_FRM_CTRL register setting, CSI_VSC = 2 or 3, it will get different result in memory.

------------------------

Hope the answer can help you !
