I would say that almost no one in the group needs the JTAG interface stuff.
The embedded mavens who can't live without probing individual memory bytes
or running insight to step through the execution will need it.

There are two modes for the USB port and it is "autosensing".

If you need to hang the Beagleboard on your computer as a USB device you
need one cable.  When the thing is running standalone and is a SBC to itself
needing to hook up to USB Ethernet appliances, hubs, etc.,  you need a
different cable and then it will set itself up as the host and not as a
peripheral device.

On the SD card programming,  I bought an SD card at Staples which came with
a USB SD adapter and this shows up as /dev/sdX  in Linux.

I purchased the DVI cable so I could sit at the console with the usb
keyboard, mouse, and Ethernet device plugged into the hub I bought.  Did I
NEED any of that?  NO because most of what people are going to want to do is
cross compile and dump code to it and tell it go run it until you blow up.
When displaying X11 graphics, etc. the thing is slow as you might expect and
most of us will set inittab to level 3.

As we build the project out we can make our own recommendations.  Rick
Hambly was most helpful to me as was that list you speak of in getting
going.  I am on the road from Sunday for over a week so I won't personally
be doing anything until after Christmas.

In preparation for order a BB for myself, I'm going through the list of
necessary and recommended (connectors, PS, and whatnot) add-ons. It's very
confusing. Most of the Shopping List is of the form, "If you want to do X,
you'll need Y." My problem isn't knowing whether I need Y, it's knowing
whether I'll need to do X.

(The mere fact of finding this so confusing probably should probably
disqualify me from taking it on at all, but never mind.)

Can anybody suggest a reasonably rich starting config, that is, enough to do
some real development without going overboard on bells and whistles?

73 and thanks

And I strongly recommend this group:

http://groups.google.com/group/beagleboard?hl=en

The Armstrong developers are there and there is a huge amount of traffic.
The archives are brimming with details.

 I have a Beagleboard since two or three weeks, and doing some experiments
with it, made complicated by my lack of
knowledge of the Linux world. I have been able to put into an SD card the
image of the Armstrong-demo Linux, and run
successfully it. My attempts to install on a different SD card a version of
Debian Lenny are unsuccessful so far, as the
 installer at a certain point wants to connect to Internet to download
required pieces of code, and the couple of
USB<=>WiFi dongles that I tried on the BB are not supported.

My questions :

A) What distribution would you choose to use the BB as a development
platform for SDR-related purposes ?
   Debian ? Armstrong ? Ubuntu (I read that it exists a port of Ubuntu to
the BB) ?

B) Does anybody have a completely installed and usable image of such a
distribution that he is willing to share, so that
I just need to copy it into an SD card ?

Many thanks from a Linux newcomer...
