Hello All, I'm trying get the serial debug working with a Macbook Pro running 10.9.5 and UDOO Quad following these instructions: http://www.udoo.org/ProjectsAndTutorial ... ial-cable/ I've install serial tools and then SLAB_USBtoUART driver "Silicon Labs VCP Driver Installer". With UDOO running and connect to laptop using USB cable into CN3 with J18 jumper in place I get this list of serial ports . . . Manual implies that "SLAB_USBtoUART" should appear in the list but it doesn't . . . If I go ls /dev/ in terminal is also doesn't appear . . . Any thought / ideas ?
