3. Beaglebone black is a low cost open source development board mainly used by developers. Developed by non-profit corporation beagleboard.org . This credit card sized board also supports embedded Linux platform. Due to the presence of so many advanced pheripherals,it is also considered to be mini computer. It has a convenient development allowing the user to interact with the PC merely via a micro USB port. Introduction

10. Step1 : First power up Beaglebone Black by connecting it with PC through USB cable. Step2 : Wait for a few  minutes  for the PC to detect BBB. Step3 : Open the command terminal and enter the following command for requesting SSH connectivity:              ssh [email protected] Now, user  has  logged in as a root in Beaglebone black. By default, password is not set for root user. Step4 : Enter the following command for setting root password in Beaglebone black:              passwd root Now, enter the password twice for the confirmation. Here when you enter the password, a blank screen is displayed instead of ‘*’ or any other symbol Beaglebone set up configuration

11. Now , reboot the Beaglebone black by entering the following command and wait for sometime:              reboot Step5 : Repeat step3. This time you cannot login without password. When you enter the step3 command, BBB will ask you to enter root password. Enter the password which  you had set during step4 and press enter key. Now , you  have entered as root. Step6 :  You have access  to Beaglebone black. Step7 : If you want internet access, you can connect Wi-Fi module or Ethernet cable with BBB. Remove the power cable (here USB cable) and attach Ethernet cable with Beaglebone black. Now, again attach the power cable with BBB. Beaglebone set up configuration (cont)
