I've been following instructions at > https://wiki.freebsd.org/FreeBSD/arm/BeagleBoneBlack I have noticed with the Adafruit cable that the serial connection sometimes just stops when I reboot or cycle the power. The following seems to reliably restart the serial port: * Leave the serial cable connected. * Remove power from the BBB * Press and hold the boot switch * Plug power back in while holding the boot switch. * Count to three and release the boot switch Finally, of course, are you sure that your cable is supported by your laptop? USB-to-serial adapters seem to be surprisingly variable. Tim
