    Hi Yuan,
    please search the simiplar issue in the e2e forum.
    to configure the I2C link between Ser and Deser, please follow up the procedure:
    1. set the i2c pass through
    2. set the alias of the paired ser in your case, and set the remote slave I2C addr. ID, and alias ID.
    3. read/write the remote slave with alias ID.

    below is one app. note for your reference, all FPD-Link have same I2C operation procedure.
