Hi, TI expert.

I have questions, please answer to me.

Q1. Refer to 1.1(sensor spec), can you give me a setting file of 953&954?

  1.1 Sensor Spec.

   - Resolution : 1920*1080

   - Frame rate : 30fps

   - Bit-depth : Raw 12bit

   - I/F : MIPI 4-Lane

   - Bandwidth : 500Mbps / lane

   - 953/954 Mode : Sync Mode

Q2. I'm set the register of 953&954. but, Input of 953(Out of sensor) and Output of 954 are different.(refer to bellow image)

Is there any problem you expect?

   

Any have a question, please reply to me.

    Hi Shin,

    You should reach out to the sensor vendor for sensor configuration. On the 953 side you don't need to do any additional configuration. On the 954 side you can configure the CSI ports using the following code:

    • Set Register 0x1F #CSI clock rate (set to 0x00 for 1.6G)
    • Set Register 0x33 = 0x03 #Select CSI Enable and CSI_Cont_Clock
    • Register 0x20 controls how RX Ports are mapped to CSI Ports 0
    • Check Register 0x35 for Pass

    The 954 CSI output needs to be greater than the 953 input. The 954 has fixed output frequency. You can set it to 800Mbps or 1.6Gbps/lane.

    Best,
