CSI-2 Rx signals and registers

[Mc2023]

Hello All,

In the i.MX RT1160 reference manual, there is the following diagram:

I looked at the code by downloading the corresponding modules and I did not find the signal/registers underlined in the snapshot above.

I even imported the example evkmimxrt1160_csi_mipi_rgb_cm7 but I did not find it.Could 

Could you tell me the corresponding variable/registers and/or functions where the following are handled

- pkt_hdr_valid

- pkt_hdr_data_type

- data_out

- pixel_cnt_count

Best regards,

Hi @Mc2023 ,

   I don't think you can test the signal wave from the MIPI-CSI directly for Figure 46-3.

  Please check chapter 46.3.1.1 Rx Local Interface Description

The Receive Local Interface is the mechanism with which the user receives packets from
the MIPI Interface

So, it is the mechanism flow, not the real physical signal in the wire, it helps your understanding.

Wish it helps you!

Best Regards,

Kerry

Hi @kerryzhou ,

Very strange that there is not equivalent in the SW for some of the signals!

As you know, MIPI interface signal is small, and the wave is from the chip internal side, to help the customer's understanding, so, you can't test the hardware signal directly.

Best Regards,
