Hello,

 

I need more details on your setup in order to help you. 

1- Are you using I2C on HPS?

    Hi Farabi,

     

    It's OK for sharing you more details

     

    No, I am using I2C without HPS

    Trying to implement I2C accesses to configure a clock component on the electronic board.

     

    The test has been performed on two different banks (6B and 6D).

    Both banks are HVIO banks are powered with 1V8.

     

    Find attached the screenshot which highlight the issue

     

    SignalTap on bank 6B which works correctly

    SignalTap on bank 6D which does not work

     

    Regards,

    Fabrice
