I have the problem of BT656-4 setting of CSI mode of IPU.
Now the guide line of PVM(Panoramic view monitor）is not correct.
■The pathway of Video System Block is below.
PVM ECU------>CVBS------>T-con----->BT656-4------->i.MX6---->CSI of IPU
■The CVBS signal is like below.
■For setting the CSI only mode of IPU, and capture of IDMAC memory,the guide line is not correct.
■I speculated that the ODD Field and EVEN Field is inverse.So I have tryed to change the setting of code1 and code2.
But the capture in memory is still not correct.
■Only change the setting of IPU2_CSI1_CCIR_CODE_2, the guide line is going to be correct.
About the IPU2_CSI1_CCIR_CODE_2,I only change the V setting of below.
CSI1_STRT_FLD0_BLNK_1ST: from 1 to 0
CSI1_END_FLD0_BLNK_1ST: from 1 to 0
Although the guide line is correct,but I don't understand the operating principle of this change.
So could you explain this case?
