|
||||
computing systems, mainly focusing around the Beagle Board environment.
|
||||
All the links that I talk about and everything will be available in the show notes for episode
|
||||
180 at hackerpublicradio.org.
|
||||
But everything will be also available through the main website, which is beagleboard.org.
|
||||
You may have to dig around a little bit, but I'll have everything referenced in today's
|
||||
episode, the links available under the show notes.
|
||||
So either way, do your hearts content enjoy.
|
||||
But the Beagle Board is a very small computing environment.
|
||||
It's basically a 3-inch by 3-inch.
|
||||
So I guess for the intelligent, that's a 3-inch squared PCB or motherboard, which basically
|
||||
is a 600 megahertz processor computer capable of running OpenGL, running fancy pants graphics
|
||||
and doing all kinds of cool stuff.
|
||||
Wow, I'm really at a lack of words here for this episode.
|
||||
This is really unlike myself.
|
||||
So what I'm going to do is I'm going to bounce over to the promotional page of the Beagle
|
||||
Board and play a little bit of their promotional stuff, because I think at this point they're
|
||||
going to do a better job explaining this than I will.
|
||||
So if you will, one moment while I patch that in.
|
||||
Welcome to the old map 3530 Beagle Board Product Training Module.
|
||||
The Beagle Board is a USB-powered embedded processor board that provides community-supported
|
||||
low-power, high-performance ARM Cortex A8 base single-board computing.
|
||||
This module will highlight the technical features, usage and benefits of the Beagle Board, show
|
||||
where to find software that verifies its hardware functionality, and provide some recommended
|
||||
peripherals to further complement the board.
|
||||
The Beagle Board is a powerful single-board computer that performs at 1200-plus drystone
|
||||
MIPS, yet it is only 3 inches square in size, and has low enough power consumption to be
|
||||
powered by a USB connection.
|
||||
With the available performance from the OMAP3 ARM Cortex A8 base processor, it is possible
|
||||
to design a Linux-based application with web browsing or multimedia functionality
|
||||
without a large development board that is typically needed.
|
||||
Based on an OMAP3 3530 applications processor, the Beagle Board includes an imagination graphics
|
||||
accelerator core, which can process up to 10 million polygons per second of graphics.
|
||||
For HD and SD video encoding and decoding, the board contains a high-performance C64X
|
||||
plus class DSP with video accelerators.
|
||||
For memory the OMAP3 3530 processor has an integrated 128 megabytes of DDR memory, as
|
||||
well as 256 megabytes of NAND flash memory.
|
||||
The Beagle Board was designed to expand easily via popular USB and standard PC peripherals
|
||||
to enable reuse of existing PC peripherals, DVID, S-Video, USB 2.0 high-speed OTG, SDMMC
|
||||
slot for memory cards, stereo in and stereo out plugs for audio, and an RS-232 port are
|
||||
included on the board.
|
||||
For real-time debugging and emulation purposes, a Jaintake connection is present.
|
||||
In the top right image, the Beagle Board is acting essentially like a desktop-based Linux
|
||||
computer.
|
||||
The Beagle Board is connected to a USB keyboard, USB mouse, USB ethernet network adapter, and
|
||||
a DVID monitor.
|
||||
It is running the angstrom operating system which was started by a small group of people
|
||||
who worked on the open embedded, open zaros and open simpad projects to unify their
|
||||
efforts to make a stable and user-friendly distribution for embedded devices like handhelds,
|
||||
set top boxes, and network attached storage devices.
|
||||
The B-Strum has already been ported to Beagle Board and is included as part of that distribution.
|
||||
In the top left image, the Beagle Board is configured for software code development.
|
||||
It is powered via USB connection and connected with a serial cable to the PC.
|
||||
The developer is able to use a network connection over the USB for application development via
|
||||
telnet, secure shell SSH, or similar networking tools.
|
||||
For lower level developments, a null modem serial cable and board adapter are helpful to
|
||||
view kernel-serial console outputs.
|
||||
In the bottom center image, the Beagle Board is used in a custom implementation of a software-defined
|
||||
radio SDR.
|
||||
A complete SDR system is established using the OMAV DSP software, stereo outjack, and
|
||||
a microphone to communicate over the air.
|
||||
The USRP, universal software radio peripheral, is connected to the Beagle Board and used
|
||||
for interfacing to different antennas for SDR.
|
||||
Now we will highlight the benefits of the low-power consumption of the Beagle Board.
|
||||
The board's low-power requirements eliminate the need of a noisy fan or heat sinks.
|
||||
Low-power means USB cable power, such that you can take the Beagle Board with you on the
|
||||
road with your laptop or a cell phone charger.
|
||||
No additional power supplies are needed.
|
||||
Beagle Board has comprehended the need for flexibility of channels for the processor to
|
||||
boots to avoid any fission lockups.
|
||||
Because boot code is in ROM, it is always there, even if the flash is erased.
|
||||
So when attempting to modify some non-open devices other than Beagle Board, you may end
|
||||
up making your device unable to boot without professional tools, and therefore becoming
|
||||
as useful as a brick, thus the term bricking.
|
||||
To solve this and overcome bricking, the Beagle Board user button allows a change in the boot
|
||||
sequence, for example booting from USB instead of from NAND.
|
||||
The USB 2.0 high-speed on-the-go OTG connection on the Beagle Board is very flexible and can
|
||||
act as a device when connected to a PC via USB.
|
||||
This can be used to provide power to Beagle Board and to emulate a network connection.
|
||||
The ability to telnet into the board is available via the network connection emulation that
|
||||
is loaded with an operating system, and can be used to perform software development without
|
||||
the serial cable.
|
||||
This is useful when the board is initialized with a working file system, or if a USB-based
|
||||
loader is generated in the future.
|
||||
As another scenario, Beagle Board can act as a host when connected to a USB hub, allowing
|
||||
an almost endless array of USB peripherals expansion.
|
||||
This will require a mini-A to standard A adapter cable.
|
||||
The first thing to do once the Beagle Board arrives is to verify that the hardware is operating
|
||||
correctly.
|
||||
Only basic software is provided in the kit to demonstrate its features, but most of the
|
||||
software is intended to be downloaded from or developed in conjunction with the technical
|
||||
community.
|
||||
At http colon slash slash beagleborg.org.
|
||||
Link to the diagnostics code and step-by-step instructions.
|
||||
At http colon slash slash beagleborg.org slash support.
|
||||
Typical PC peripherals and connectors that are useful with the Beagle Board are available
|
||||
from Digi-Key.
|
||||
If USB power is not being used, an external power supply with a barrel connector is necessary.
|
||||
Digi-Key's 5V T450-P5P-&D power supply meets the board's power needs and is suitable
|
||||
for use.
|
||||
For boot loading and boot console I-O, a no-motum serial cable, such as AE-9879-&D, may
|
||||
be needed.
|
||||
In HDMI to DVI-D cable, AE-10260-&D enables connection to digital monitors via DVI-D.
|
||||
A USB hub, D8-70227-&D, is also useful when connecting multiple devices.
|
||||

|
||||
and peripherals resources.
|
||||
The Beagle Board has an open-source community that is full of emerging ideas, such as wearable
|
||||
computers, Google Android ports, various Linux games, and a port of the open-source
|
||||
OKL4 micro-curnal.
|
||||
In summary, the Beagle Board is a USB-powered embedded processor board that provides community-supported
|
||||
low-power, high-performance ARM Cortex-A-8, based single-board computing.
|
||||
Beagle Board's website is a community of open-source developers and hobbyists that provide
|
||||
unpaid support for users.
|
||||
This openness allows sharing of code, keeps cost low, and enables more people to participate.
|
||||
Support is also available online 24-7 to access fellow developers at http colon-slash-slash-beagleboard.org

|
||||
Alright, I think that summed it up much better than I perhaps way ever could.
|
||||
I left the little in part and the little digikey kind of sound and add in just because it
|
||||
was their little training module that I stole the audio from, and basically they're the
|
||||
people that are selling it.
|
||||
You can get the motherboard, which has the embedded ARM process for running at 600 megahertz.
|
||||
It's got 128 megabytes of RAM, it costs $150, and this thing runs off two watts of power.
|
||||
So what does that mean?
|
||||
Basically, it means that a non-volt battery can power it for at least a couple hours.
|
||||
So we're talking about a fairly powerful unit, at least as far as without a monitor and
|
||||
all extra stuff attached to it.
|
||||
It's a pretty powerful little computer that you can tote around in your pocket or like
|
||||
they suggested, which I thought was pretty cool, the idea of wearables.
|
||||
I'd like to throw in the idea of robotics, but all kinds of different ideas just kind of
|
||||
spring to mind.
|
||||
I'm not going to really ramble on anymore on this episode, but I just thought this was
|
||||
a really cool subject and idea, just to throw out there, figured it would be a great episode
|
||||
of HBR, let everybody just hear about this stuff and think about it.
|
||||
At TheBegelboard.org website, they have also Beagleboard.org slash media, it's in the show
|
||||
notes as well, but they've got a bunch of pictures, actually, they've got a Flickr group
|
||||
and they've got a bunch of videos on YouTube.
|
||||
So I know that they've done a Linux outlaw, has an interview with these guys as well as
|
||||
I think they were at the log radio thing this year.
|
||||
So whatever you guys that may be familiar with that, probably know a little bit more.
|
||||
I don't know, I've been busy with school so now that I've just recently finished, I'm
|
||||
just now starting to catch up on all the podcasts and stuff, been way behind.
|
||||
So this may be old news if so, I apologize and if not, I hope you enjoyed either way.
|
||||
Hey, maybe you enjoyed.
|
||||
But regardless there will be somebody here different tomorrow to bring you another wonderful
|
||||
and hopefully exciting episode of Hacker Public Radio.
|
||||
Thanks for tuning in, we'll see you tomorrow.
|
||||
Thank you for listening to Hacker Public Radio, HBR is sponsored by Thero.net, so head
|
||||
on over to VARO.nc for all of the team.
