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.

> Now I just gotta figure out what to do with this beastie! > Anyone else get one yet? 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. -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: http://www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: http://www.voti.nl/hvu C++ on uC blog: http://www.voti.nl/erblog

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.

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.

To summarize experiences of people on this thread - "nice" device, but nobody has made it to work, is it correct? Kind of makes me wonder if I should ever consider RPi at all. 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. Sergey Dryga http://beaglerobotics.com

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

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.

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. {Original Message removed}

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.

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. TTYL

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. TTYL
