I am trying to connect an external serial device to the udoo. Specifically a serial LCD display. And I am trying to send status messages to it. I see that ttymxc0 is already visible in /dev. But what pins are they? Any help would be appreciated.
u have two choice, u can connect directly to due serial port and iMX6 serial port. If i'm not mistaken, ttymxc0 is CN6(Debug USB), you also can use ttymxc3. Before make any connection on udoo board please read the manual first http://udoo.org/download/files/Document ... 8_2013.pdf. Some setting maybe need to look at before make modification.
