    How to make the uart0 work?

    Hui.Wang

      From the page 21 and page 23 of galileo_schematic.pdf, if we want the UART0 work, we need to set LVL_OE (page21) to hgih and set IO0_MUX and IO1_MUX (page23) to low, the LVL_OE is from the quark CPU (gpio_sus2) and the IO0/1_MUX are from the pin14 and pin15 of CY8C9540A, I don't know how to control those pins, does anyone know how to control LVL_OE, IO0_MUX and IO1_MUX? Is there kernel drivers for those pins?
