Dear All,



My customer is trying to connect the original camera to MIPI-CSI2 interface on MCIMX6Q-SDP.

But, the video signal (YUV422 1080p@30fps) can not be acquired right.


They checked the difference of MIPI-CSI2 register between original camera (Failed) and OV5640 (Success).

Below bit was different.

Refer to 40.6.6 General settings for all blocks (MIPI_CSI_PHY_STATE) in IMX6DQRM(Rev.2).

- Original camera (Failed) --> 0x230

- OV5640 (Success) --> 0x330



Field 8 phy_rxclkactivehs

Indicates that the clock lane is actively receiving a DDR clock

Default Value: 0




Could you tell me the condition to become "phy_rxclkactivehs = 1"?


Best Regards,
