seeed studio BeagleBone Green User manual

BeagleBone Green
SeeedStudio BeagleBone Green (BBG) is a low cost, open-source, community
supported development platform for developers and hobbyists. It is a joint
effort by BeagleBoard.org and Seeed Studio. It is based on the classical open-
source hardware design of BeagleBone Black and developed into this
differentiated version. The BBG includes two Grove connectors, making it
easier to connect to the large family of Grove sensors. The on-board HDMI is
removed to make room for these Grove connectors.
Boot Linux in under 10 seconds and get started on development in less than 5
minutes with just a single USB cable.

Getting Started¶
Note
This chapter is writing under Win10. The steps are familiar for the other operate
systems.
STEP1. Plug in your BBG via USB
Use the provided micro USB cable to plug your BBG into your computer. This
will both power the board and provide a development interface. BBG will boot
Linux from the on-board 2GB or 4GB eMMC.
BBG will operate as a flash drive providing you with a local copy of the
documentation and drivers. Note that this interface may not be used to re-
configure the microSD card with a new image, but may be used to update the
boot parameters using the uEnv.txt file.
You'll see the PWR LED lit steadily. Within 10 seconds, you should see the
other LEDs blinking in their default configurations.
 D2 is configured at boot to blink in a heartbeat pattern
 D3 is configured at boot to light during microSD card accesses
 D4 is configured at boot to light during CPU activity
 D5 is configured at boot to light during eMMC accesses
STEP2. Install Drivers
Install the drivers for your operating system to give you network-over-USB
access to your Beagle. Additional drivers give you serial access to your board.
Operating System USB Drivers Comments
Windows (64-bit) 64-bit installer
Windows (32-bit) 32-bit installer
Mac OS X Network Serial Install both sets of drivers.
Linux mkudevrule.sh Driver installation isn't required, but you might find a few udev rules hel
p
Note
For Windows system, please note that:
 Windows Driver Certification warning may pop up two or three times. Click
"Ignore", "Install" or "Run"
 To check if you're running 32 or 64-bit Windows see this.
 On systems without the latest service release, you may get an error
(0xc000007b). In that case, please install and retry:
 You may need to reboot Windows.
 These drivers have been tested to work up to Windows 10

Note
If you don't find the upper tracing light, please press the RESET button to reset the
board.
When the flashing is complete, all 4 USRx LEDs will be off. The latest Debian
flasher images automatically power down the board upon completion. This can
take up to 10 minutes. Power-down your board, remove the SD card and
apply power again to be complete.
Grove for BBG¶
Grove is a modular, standardized connecter prototyping system. Grove takes a
building block approach to assembling electronics. Compared to the jumper or
solder based system, it is easier to connect, experiment and build and
simplifies the learning system, but not to the point where it becomes dumbed
down. Some of the other prototype systems out there takes the level down to
building blocks. Good stuff to be learned that way, but the Grove system
allows you to build real systems. It requires some learning and expertise to
hook things up.
Below listed the Grove modules that work well with BBG.

Cape for BBG¶
You will need some expansion board when you start a project. There're many
cape for BBG already, they include LCD display, motor driver as well as HDMI
expansion etc. Below is some of them recommend.

FAQ¶
1. What is the different between BBG 1 and BBG 2?
We have updated the eMMC on Beaglebone Green in 2016. So the previous
firmware for BBG1 is not workable on BBG2, but the new firmware is ok on
BBG1 and BBG2.
