Hello, I try to connect the OV12895 to the CX3(denebola). I am Want to capture video at 1080p, 1-bit RAW data, over 4 - lane.
Here is my CX-3 configuration.
The issue is , I am not getting any data and GPIF and DMA callback functions are not called.
May be, I misunderstood the CX-3 configuration.
Please, Help me to resolve issue.
Thanks
Solved! Go to Solution.

Hi Hardik,
I notice that you get error since the wrong THS-prepare value. Could you please check with OV?
In addition, please measure the waveforms of pins G6/H5/H8.

Hi hardik,
Please first confirm that all the MIPI CSI-2 input parameters are correct from FAE of OmniVision.

Thanks, I am collecting MIPI CSI-2 input parameter from sensor manufacture.
Meanwhile, I have question regarding XRESET Pin.
As this PIN is used to reset sensor, It is necessary to pull down XRESET of CX-3.
In our case, PWDN pin from sensor connected to XShutdown of CX-3 and XShutdown pin from sensor connected to CX-3 XRES. Hence, both the PIN is in high state to operate sensor. Is it OK?

Hi Hardik,
XShutdown and XRES are provided to operate sensor. You could assert both high and low on these two pins. That depends on the requirment of sensor. You need to read the datasheet of OV12895.
You could invoke CyU3PMipicsiSetSensorControl to set HIGH/LOW on these pins. For more details, please refer to CX3 TRM.

After resolve some hardware issue, I can get the Data from the sensor. However, still It has some issue in data transition.
I got random size of the frame every time. What could be the reason for this ?
I got following when enable MIPI Error thread.
MipiError cnt frmErrCnt= [255]
MipiError cnt crcErrCnt= [0]
MipiError cnt mdlErrCnt= [255]
MipiError cnt ctlErrCnt= [0]
MipiError cnt eidErrCnt= [0]
MipiError cnt recrErrCnt= [0]
MipiError cnt unrcErrCnt= [255]
MipiError cnt recSyncErrCnt= [0]
MipiError cnt unrSyncErrCnt= [0]
My MIPI Receiver settings as follow
