Hello everyone,
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.
IPU2_CSI1_SENS_CONF:0x04000A30
IPU2_CSI1_SENS_FRM_SIZE:0x020C02CF
IPU2_CSI1_ACT_FRM_SIZE:0x01DF02CF
IPU2_CSI1_OUT_FRM_CTRL:0x00000003
IPU2_CSI1_CCIR_CODE_1:0x010D07DF
IPU2_CSI1_CCIR_CODE_2:0x01040596
IPU2_CSI1_CCIR_CODE_3:0x00FF0000
■I speculated that the ODD Field and EVEN Field is inverse.So I have tryed to change the setting of code1 and code2.
IPU2_CSI1_CCIR_CODE_1:0x01040596
IPU2_CSI1_CCIR_CODE_2:0x010D07DF
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.
IPU2_CSI1_CCIR_CODE_1:0x010D07DF
IPU2_CSI1_CCIR_CODE_2:0x00040584
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?
Hi igor,
I have read this file and the setting is according to this file.
But I can't understand the meaning of only change the Vbit setting as below.
CSI1_STRT_FLD0_BLNK_1ST: Vbit :from 1 to 0
CSI1_END_FLD0_BLNK_1ST: Vbit from 1 to 0
From the status, only one line blanking is changed.
But according to below table, if change the EAV and SAV of the first blanking that will be changed for 16 lines not one line.
Thanks&Best regards!
