| + | Note that the framebuffer (fb) driver is not supported on the Black and White models. You will need a serial interface cable to connect. Please review [[http://dave.cheney.net/2013/09/22/two-point-five-ways-to-access-the-serial-console-on-your-beaglebone-black | Dave Cheney's article]] on connecting via the serial port. Users of Apple products may want to review [[http://pbxbook.com/other/mac-tty.html | Mike's PBX Cookbook article]] on using Terminal for serial communication. In Terminal, the command 'screen /dev/tty.usbmodem* 115200' works well (replace the * with the appropriate label). | ||
