BeagleBone black is single board linux computer that can be used as a general purpose linux computer or as a platform for embedded hardware project. I am using BeagleBone Black rev 0A6A S/N 0414BBBK2103.
Some of the features of BeagleBone black are:
- 1 GHz ARM processor.
- 512 MB of RAM.
- Angstrom Linux operating system installed out of the box to 2 GB built-in flash storage.
- Capability of booting directly from micro-SD card.
- Quick boot time roughly 10 seconds.
- 7 Analog and about 60 digital input/output pins that can be used for communicating with various electronic devices.
- An Ethernet network port.
- A micro-HDMI socket.
- A USB port to attach peripherals.
- USB Network bridge capability.
There are different ways for connecting to beaglebone black. The easiest of them is to connect via USB. Other ways include connecting via HDMI or though internet via Ethernet cable.
a. Connecting Via USB
Some other things that you would probably need to know:
a. To Shutdown the device, on the shell prompt type 'shutdown now'
b. To change system date of device, on the shell prompt type
date -s "16 SEP 2014 18:31:00"
If you connected to network, time can be updated over network using
ntpdate -b -s -u pool.ntp.org
c. Sometime you may need to sync hardware clock with system clock, this can be achieved using
hwclock --systohc
To see current time on hardware clock type,
hwclock --show or hwclock -r
d. Cloud9 IDE: This is default IDE installed on the beaglebone. When connected using USB, type in browser http://192.168.7.2:3000/
