DS90UB936-Q1： DS90UB936-Q1 device address

Part Number: DS90UB936-Q1

My camera uses AR0144, its internal integration TI 935, I connect to 936 development board through harness, and then connect to s32v through Mipi interface. How many device addresses can I find on I2C bus after hardware connection?

Now I can only find a 936 I2C device address 0x30, is it necessary to configure 936 to see the address of 935 and camera? Or is there something wrong with my hardware board?

    Hello Meng,

    It sounds like your devices aren’t properly linked. Once linked, you should see device addresses for the 935/936 and camera.

    To check your link, you need to verify the aliases by doing the following:

    - Des Reg 0x4C: Select the right RX port to write
    - Set/Check real I2C addresses
    - Reg 0x5B SER DEVICE ID: Set the real serializer I2C address. This is typically loaded already
    - Reg 0x5D SlaveID[0]: Set the real CMOS sensor I2C address
    - Reg 0x5C SER_ALIAS_ID: Set the alias serializer I2C address
    - Reg 0x65 SLAVE_ALIAS_ID[0] (camera alias ID): Set the alias CMOS sensor I2C address

    Once the aliases are set, you can communicate with the 935 using the alias ID’s that you assigned.

    Best,

    Liban H.
