RT1172 CSI for Parallel Raw12 from TOF sensor

[AntonyHan]

I would like to receive 12bit raw data from TOF sensor thru parallel interface.

I had configured CSI(Camera Sensor Interface) of IMXRT1172 for the interface format.

However it cannot receive the frame.

Let me introduce about the interface signals and  the CSI configuration.

 

One frame has 320*16 resolution, one pixel has two byte length.

One group is configured with four frame.

Actually, I have only to receive one frame and copy the contents to another memory space.

I would like to focus on one frame and receiving one frame.

Unfortunately, my firmware fail to receive the frame data.

CSI interrupt callback function is called in every frame.

I just activate interrupt source for SOF and EOF.

There are 20frame in a second and there are 20 interrupt call.

I got to know the only SOF interrupt source influence the callback function but EOF.

 Please let me know how to relevantly configure the CSI peripheral to receive parallel raw12 data from TOF sensor.

Thank you

Hi @AntonyHan,

I'm afraid that the i.MX RT1176 does not support RAW data formats, as mentioned on the following community post: RT1170: Using MIPI-CSI with grayscale or raw image sensors - NXP Community.

If you wish to use this TOF sensor with RAW12 image format, you will require a i.MX MPU: Solved: How to support RAW12 output on i.MX8M Plus, Linux system - NXP Community

Sorry for the inconvenience this may cause.

BR,
Edwin.
