    Hi,
    

    

    I aa using a ADRV9026 transciever currently. I want to validate my gigabit lanes by conducting PRBS test. Following is my initialize sequence;
    

    1. Init clock source that provides required sysref and clocks to adrv and fpga
    

    2. Init adrv9026 with respect to sample application
    

    3. Init fpga jesd204b support
    

    4. init adrv9026 jesd204b
    

    5. get link up
    

    6. conduct two ways prbs test
    

    I am following sequence given below to conduct prbs test from adrv to fpga but I see all data is zero reaching to fpga jesd204b core. I can not produce prbs9 and prbs23 datas but when I choose prbs7 I can see produced data. I am not sure about whether I skip any required step or my init sequence wrong. Thank you for your help in advance.

      Can you please cross check with the sequence provided with the attached script and see if you are able to verify PRBS . Please let me know if you have any other questions.

        High, I am trying same sequence but I still cannot verify generated prbs on fpga at adrv prbschecker. Also I cannot generate prbs9 and prbs23 at adrv prbs generator. Can it be any bug related with these things.
