Now I just gotta figure out what to do with this beastie!

Anyone else get one yet?

Offhand I'll be connecting some things to the GPIOs, haven't gotten my
feet wet yet, any pointers for pure homebrew hardware stuff with this
thing?

Thanks, TTYL

I've had mine for a couple of weeks.  Played with a couple of Linux distros and found them as unfriendly as I remembered and almost unusably sluggish in the case of the standard Debian distro.
I'm now running the alpha release of RiscOs  for the RPi and what a revelation in terms of speed!  Admittedly it's a bit limited at the moment e.g. a little fussy on SD cards and only a few basic apps included (though you can install the NetSurf browser), but the Linux distros will need to make a quantum leap in speed to compare with it.

Cheers

Mike

It's on my desk. I put a serial bootloader on it, connected an FT232 and a PFET for power switching. Now I can download and run fully hands-off. Totally bare metal. So far I can blink a LED.

I used David Welch's github entry at https://github.com/dwelch67 as a guide. The bootloader his, with some changes. I added xmodem to xwisp, maybe I'll add it to lpc21isp (if the onwer agrees). I used the startupfiles from a Linux distro, so my bootloader is loaded at 0x0, not at 0x8000 as happens with the boot files he used.

I've had mine for a couple of weeks now. I started to get the XBMC media streamer to work and did so after trying out some different SD cards.

I have a couple of PC Windows programs that I would like to port to the RPi but these needs an RTC for loging data. I guess I could add one on the GPIO, I2C perhaps.

What is the best route to port windows software to the RPi? (Sorry for stealing the thread)

Is that yellow connector a composite video? Why would someone need that if
it has the hdmi on the other side?

Anyway, nice device for the price!

There is Raspbian which uses hard float Wheezy base (whatever that is) instead of software float and is reported to be much faster due to that. Work in progress at the moment though.

I have two.
Farnement 14 advice said "one per order" so I ordered a second one a while ago.
Nic elady who rang up the other day re something else was shocked to
hear I had two.
She said it was strictly one per cistomer so far.
I pointed out what their ad had said and she reiterated the party line.
No problemo - my reality trumps her party line :-).
BUT     I don't want them to jusyt be shelf ware- even for months
while their world gets more stable.
BUT     it is evident even from this thread that for a non-Linux man
the get it going curve is a little less steep than desirable (steep is
good, just nobody notices the terminology is backwards :-) ).
AND     reality informs me that I am not going to spend the time to do
it the hard way (regardless of how good that may be for one's
character).
SO       What would be nice [tm] is a spoon fed do
this-&-this&-this&-this&-this&-this&-this & it's away and it's close
enough to Windows in this mode that you can almost use it.

Any advice on where to find the best version of such a spoon would be
appreciated - and not just by me.

My early aim is multimedia slideshow* but much else suggests itself.

These applications are written in C++ using MFC with Microsoft C++ 6.0. They all use serial ports (RS232 and RS485) to interface with different types of sensors.

I am not familiar with linux.

To summarize experiences of people on this thread - "nice" device, but nobody

As for the slideshow requirements: I see a (i) fast way - something like a
labtop/tablet with a slideshow program, (ii) slower way - program PIC to do that.

I do it with a netbook now. I'd like something more purpose directed
which, while not quite "
disposable" was cheap enough to leave with people for a while.
External screen is required for netbook and RP and is quite often
available at a site or home so the cost of that is not an issue.

The appeal of the RP over any alternative compact hardware that I've
seen so far is the integrated 1080p video. The actual program is "just
a matter of programming".

If you don't know what you're going to do with it, then you probably
shouldn't consider it. I've made mine work, but then I don't have
unrealistic expectations about what I want to do with it - for now I'm
just having a play around with what it can do, trying out programming
in Python, and investigating the graphics/gaming potential. I'm also
planning on trying to run the VM software we use at the school I do IT
support for, to see whether it's possible to use a RPi to run the user
interface for the kids instead of the old PCs we currently use (the
base OS running the VMs is linux, so we stand a decent chance - though
I suspect the performance may not be sufficient). In the longer term
put together a proposal to use them for computing lessons - after all
the point people still seem to be missing is that these devices are
intended as basic devices to introduce kids to basic computing -
hobbyist use is just a sideline, and if it doesn't do what you want it
to, then it's probably not intended to.

They had me at " ... 1080p video ..."
I may have escaped its event horizon if they had not also said " ...
dual USB2, Ethernet. ...".
The very substantial rest is icing.

In reply to Sergey's comment ""nice" device, but nobody has made it to work,
is it correct?"

Depending on what you refer to as "work" mine is running perfectly. I am
using the first of mine as a low power "appliance" computer. It is happily
talking to my Insteon PLM and managing the automation of my home.

I have expressed interest at Element14 for a second one, not sure what I
will do with it yet, but there are a couple of projects that I might use it
for.

Is it possible to run VirtualBox on RPi ? BCM2835 doesn't seem to be
supporting virtualization but it was already being done before VT-x so
it -might- be possible.

Doesn't appear so: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=10&t=4842.

QEMU is a different beast, however ;]

No, not correct.

The Raspberry PI is a Linux machine. Anybody familiar with Linux feels
right at home.

Even better it runs a distro I like and am familiar with.

Getting a Raspberry Pi and expecting it to be "windows like" means the
person had the wrong expectation. That is not a fault of the hardware.

If your display device doesn't have HDMI/DVI?

Lots of embedded type apps where composite video is king.

My first boot was with the composite port simply because that was the
closest thing I had available to me.

For video/text on a small screen composite is "good enough" for many
usage cases.

In the UK there are now a lot of analogue TV sets with nothing to do, as the transmission is now all digital, so in a lot of cases feeding composite video into a SCART connector would be the way to go ...

You can  buy some nice little composite-input LCD monitors intended for in-car use very cheaply.
e.g, currently on Ebay : 3.5" £12.50, 4.3"  £15, 7" around £20

You may need a large-ish font size to be readable though!

It can be. But I like it as a very fast ARM CPU with an amazing amount of RAM (and some other peripherals).
