    FX3 Pin D2 (I2S_SD ) power up value

    gokul.prasath.nallasamy

       Hi all,

         

       

         

      I have a EZ-USB FX3 DVK, when I turned on the board with the USB Boot mode, I observed that the pin D2(I2S_SD) is toggling with around 400KHz. I need to know why this pin alone is toggling but other I2S pins are at Low state. (I did not loaded the FX3 any Firmwares, FX3 USB Bootloader firmware residing in the BootROM only loaded).

         

      Please help me, If there is any settings to make this pin to be at low during startup. Or is it possible to change the BootROM present in the FX3 ROM.

         

       

         

      Thanks,
