First Boot
First boot with BeagleBone Black (BBB) is best done by using a serial communication program like CuteCom or Putty.
Attach the USB connector to your PC and issue this command to find the tty-port that will be created:
$ ls -lart /dev
drwxr-xr-x. 2 root root 80 Aug 16 13:19 bsg crw-rw----. 1 root disk 21, 1 Aug 16 13:19 sg1 drwxr-xr-x. 2 root root 3900 Aug 16 13:19 char drwxr-xr-x. 22 root root 3560 Aug 16 13:19 . brw-rw----. 1 root disk 8, 16 Aug 16 13:19 sdb drwxr-xr-x. 6 root root 120 Aug 16 13:19 disk drwxr-xr-x. 2 root root 200 Aug 16 13:19 block crw-rw-rw-. 1 root dialout 166, 3 Aug 16 13:19 ttyACM3 crw-rw-rw-. 1 root tty 5, 0 Aug 16 13:20 tty crw-rw-rw-. 1 root tty 5, 2 Aug 16 13:21 ptmx
The above list show the devices created when attaching the USB cable. The line of interest here is the ttyACM3 - might differ on your system.
Since users is normally not member of the dialout group the quickest way to gain access to the tty-port is to issue this command:
$ sudo chmod o+rw /dev/ttyACM3
This will give you access to the port.
Now open the CuteCom or Putty port on a serial line using /dev/ttyACM3 and 115200 bps as settings.
You should see an output like this:
Login timed out after 60 seconds. \0x1b[r\0x1b[H\0x1b[J Debian GNU/Linux 7 kolles-beaglebone ttyGS0 default username:password is [debian:temppwd] Support/FAQ: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian The IP Address for usb0 is: 192.168.7.2 kolles-beaglebone login:
You can now login using the defaults given.
Also try to issue
$ ssh debian@192.168.7.2
This will open an ssh connection over the USB cable to the BBB.
