 Beaglebone black set up configuration
 Reference

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.

5.  2x PRU 32-bit microcontroller
 512MB DDR3 RAM
 4GB 8-bit eMMC on –board flash storage
 3D Graphics accelerator
 Floating point accelerator
 USB client for power & communications
 USB host
 One Ethernet port
 HDMI port
 2x 46 pin headers
 SD/MMC interface
 UART,SPI,I2C,CAN built in processor
 ADC,PWM,LCD built in processor

6.  Various Linux distributions supported (Debian, ubuntu, android etc.)
 Various High level languages supported (C,C++,Python, java etc.)
 Easy booting process.
 SSH connectivity with PC.

8.  Beaglebone black contains 2 pin header each containing 46
pins.
 Left side pin header is P9 and right side pin header is P8.
 Pinout consists of various power
source,GPIO,SPI/I2C,PWM,LCD data and control in, UART
pin etc.
 Some pins can be put to a multipurpose use.
 Reference voltage of VDD_ADC pin is 1.8V.

9. Key features of the Cortex-A8 core are:-
Frequency from 600 MHz to 1 GHz and above.
Super scalar dual-issue micro architecture.
NEON SIMD instruction set extension.
13-stage integer pipeline and 10-stage NEON pipeline.
VFPv3 Floating Point Unit.
Thumb-2 instruction set encoding.
Jazelle RCT.
Advanced branch prediction unit with >95% accuracy.
Integrated level 2 Cache (0–4 MiB).

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 root@192.168.7.2
 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

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.
