    Hi,


    What you provided is the evaluation kit schematic. Is it possible to get your schematic so that I can understand if there is any wrong with your connection? The reason is that I am not sure what you modify on your board that cause the issue.

    Hi,


    I observed that you are using 1K Ohm pull up resistor on nStatus, CONF_DONE and nConfig pin. May I know if it possible to change it to 10K ohm resistor?


    The other thing is that could you make sure that your Max 10 pin connection to the board is good?
