    Curie’s Startup time changes

    fujix-s

      Hello, everyone.

       

      Now, Curie's start time may be delayed, I am in trouble.

      It usually starts running in about 1 second, but sometimes it gets longer by about 2 seconds.

      I expect the same time every time.

       

      Examining it seems that TX of UART 1 is related. But I do not know what is wrong.

      What can be thought of?

          I'm sorry. It is the RX pin of Curie, not the TX pin.

          When turning off the power supply of the board, we found that startup is delayed at the next power-on when the voltage of RX pin falls below Curie's power supply voltage.
          TX of another module is connected to the tip of the RX pin.
          I do not know the reason for this.

            Hello Satoshi,

            Thank you for your interest in our Intel products.

            Are you using the Curie module in a custom board? Do you have a board like Arduino 101 or tinyTILE?
            Can you please provide us with more details about your configuration, like what you are trying to do, any sensors connected to the board, power supply specs, how you are measuring the board's start time, etc.. Basically all the details that can help us reproduce. 

            Regards,
            Octavian
