My end goal is to output video from the DVI port in 640 x 480
resolution (The display I'm working with only accepts this resolution)
I have followed the beagle diagnostics and my hardware is working (I
see a 1280x720 image on a regular monitor). I tried using the xrandr
to change the resolution, but the command does not exist in the sample
code. I understand I need to rebuild the kernal with my desired
resolution

in some directory in your home (e.g. create anew directory linux-beagle)
git protocol (i.e. git://.. ) should always work, git over http://… is the fallback if you have e.g. firewall issues. And with http://… people sometimes have issues.
I don't seem to have make in my path so I can't
make
or
make install
I tried the export command line but that didn't make a difference.
What would you recomend?
If I understand you correctly, you can't execute 'make' on your x86
development PC? Then you have to set up your x86 (Linux) development
PC to be able to compile x86 binaries. Downloading source packages and
compile & install them with make and make install is the standard way
under Linux. If you can't, you should set up a system for this, first.

If it is (a), the u-boot support for beagle is not in mainline tree yet.. you need u-boot with beagle support -> you can either pull (b) or if you like, could also pull u-boot tree that Steve maintains here: http://www.sakoman.net/cgi-bin/gitweb.cgi (See u-boot not u-boot v2).
By the way, a quick and dirty way of seeing if beagle is supported run: grep beagle Makefile

There is a pinned e-mail in this thread that talks about how to patch 1.3.2 to build u-boot. I’d say that rebuilding u-boot isn’t useful to most people and isn’t required to rebuild a new kernel. Still, I pointed some people in the direction of that thread so that they’d understand what the differences are between what is on the mainline tree and what is requried to support Beagle.
For anyone looking to do any u-boot development with Beagle, aligning with Steve Sakoman’s u-boot tree is the right way to go as he and Dirk are making plans to push patches to the mainline.

Jim,
I think you should likely just use the pre-build Angstrom u-boot (or the one already flashed on the board) and spend your effort on rebuilding the kernel. Based on other messages, I believe you are most interested in figuring out how to change resolutions. I thought there were some patches to the linux-omap git tree in Angstrom[1] that provided some standard resolutions down to 640x480, but I did not find them. I was able to find patches[3] by browsing Steve Sakoman’s tree[2].
This message is for Tier's. What is the recommended way to share files? Is it from an external (personal?) website? Is there an internal FTP? Beagleboard.org upload?
It depends on the audience. There is a BeagleBoard.org upload, but I
prefer not to share that broadly as it isn't the most secure/stable
solution. The Google Group has a "Files" area that I went ahead and
turned on for you. Of course, you can also attach files to e-mails
sent to the list, though that might irritate some recipients.
For your own project that may only interest a sub-set of Beagle Board
users, I highly recommend that you utilize a project hosting service
such as code.google.com, sf.net, or codeplex.com, as recommended on
the http://BeagleBoard.org/project page. Each of those services have
the ability to host files. You should also register your project on http://BeagleBoard.org/project.
Texas Instruments is developing a Pico Video Projector Kit as a peripheral for the Beagle Board. The PVPK is based upon the DLP™ Pico Projection technology
The stand alone pico projector will support VGA resolution (640 x 480), RGB 888 input through a DVI interface. (The physical connector on the projector will be HDMI).
The PVPK will be available for sale to the public in January 2009. We would like to develop several Beagle/PVPK demonstrations for trade shows prior to production release. We are looking to the beagle community to help develop these demonstrations
T.I. would like to promote some of the innovative projects that you are developing along with pico projection technology. Ideally we would like up to five different demonstrations for trade shows.
If you are interested in participating or have ideas of how the beagle community could best be served by this, please let me know.
Anyone whose project is selected and functional for a demonstration will receive a production pico-projector when they are available (around December ‘08)
We look forward to hearing your thoughts about this opportunity

hey, that's really a great thing! It solves a major problem you have with mobile
devices:
The physical size of your display is the limiting factor for shrinking
smartphones, PDAs and similar mobile devices.
A kind of 'Beagle-Smartphone' prototype might be an interesting project. I see
that the size of the Beagleboard itself won't allow a really small device, but
it should be ok for demonstrating the technology and the idea behind it.
Hey, I am a student interested in embedded programming. I just
finished an internship at Kiva Systems in Woburn, Masachusetts
(www.kivasystems.com) where I worked with a PIC 18F8585 processor. I
was thinking of creating a UMPC with the Beagle Board I just purchased
and would love to incorporate the projector into my project. Any
information would be great
An earlier version of our pico projector was laser based. It was demonstrated at 3GSM. I know of at least 3 reasons why laser illumination was not pursued for product:
1) The image quality of laser illumination was inferior to LED illumination
2) Lasers cost more than LEDs
3) Lasers are dangerous
Thanks for your inputs.
There may be an industrial application for a laser-pico. Please submit your ideas for discussion.
Yes lasers are dangerous all coherent beams of energy are but if the beam
could scan and pulls under 50hz and be slightly refracted it would be safe.
Solid state lasers use less energy than LED's that was the ideal reason.
However with new battery technology coming about it will probably cover the
excess that LED's consume..
I am an engineer working in a company for stb/mobile market.
My first idea is to make a demo with the DLP for a rich user interface (Flash based)
The idea is that this ui is remotely controlled by a wiimote.
It is possible to click/drag and drop items/widgets on the screen remotely.
I have already made this demo on a linux STB for myself. So porting the demo on the beagleboard
will not be an issue. With the powerful 3530, it would be interesting to increase the number of items.
If you are interested, I can send you a working preview on pc.
