    Miguel,

     

    Additional input to you :

    1. UART2 has no pullup or pulldown resistor (same as leopard board schematics)

    2. ASP0 port has no pullup or pulldown resistor (same as leopard board schematics)

    3. ASP1 port : not connected to any audio codec and has no pullup or pulldown resistors.

    Does these ports needs to pull up or pulldown resistor to solve my above problems ?

    Regards

    Sudarshan
