Hi, Is it possible to enable / disable pull-up / pull-down resistors on the Freescale IMX gpios configured as inputs ? I have an external device connected to a GPIO put that is active_high. The external device connects with 3.3V for a logic HIGH and 0V for a logic LOW. I would like to have the following behavior on the UDOO: 3.3V connected = pin marked HIGH 0v connected = pin marked LOW nothing connected = pin marked LOW However, when nothing is connected to the pin it is marked HIGH. I would like to configure the pin with a pull down-resistors so that it is pulled to ground when nothing is connected. Is it possible to do that on a running system ?
