Re: XO-1.75 progress
Excerpts from Chris Ball's message of Wed Nov 10 22:01:28 +0100 2010: bringup last week. The 1.75 machine lives in the same industrial design (display, case, batteries) as the XO-1/XO-1.5, but uses an ARM system-on-chip from Marvell -- the Armada 610/MMP2. Congratulations on the successful bring-up and thanks for letting us know! Will Marvell publish additional documentation on the SoC, like they do for the Kirkwood series and like what's available for XO-1 / XO-1.5? Do you know about compatibility of the functional blocks that are part of both product series (e.g. CESA)? What are the chances for an Open Source 3D-capable graphics driver (for desktop effects)? What about video acceleration?

Re: XO-1.75 progress
Bert - No, not at all. Our plans were, and are, to build XO-1.75 laptops with touchscreen support. That's an essential step in our tablet development, we think. That will essentially provide us with a 7.5 4:3 tablet inside a laptop case. That's a little small for a tablet, but it allows useful software development for a tablet model quite early - with a keyboard and mouse as fallback tools. But I think it's important to think about XO-1.75 more as a set of technologies than as a product right now. We're still experimenting. We're learning, for example, that while interested deployments like the idea of an XO laptop with a touchscreen, they're also very sensitive to price, and aren't likely to purchase machines with an optional piece of hardware that isn't necessary for the device's operation, especially when that hardware will add more than $10 to the cost of the machine. So we're certainly going to produce XO-1.75 machines with touchscreens for software development, but it's entirely possible that no machines will be delivered to deployments with touchscreens installed. - Ed On Nov 11, 2010, at 7:32 AM, Bert Freudenberg wrote: On 11.11.2010, at 12:49, Ed McNierney wrote: [...] we're talking about XO-1.75 right now, which is a laptop.

Re: XO-1.75 progress
Marvell's Armada SoC family is complicated. There are multiple product lines, and multiple products in each product line, with new ones coming along all the time. So it's hard to nail down just which device is the latest and greatest at any time. OLPC is (unsurprisingly) doing something a little unusual. We're trying to create a laptop (first) and then a tablet, each of which is a really full-function, general-purpose device. If you look at Marvell's ARM product selector guide and try to figure out which SoC is recommended for a laptop, you won't find one. And if you look for tablets you find either (a) SoCs for e-book readers or (b) SoCs for entertainment devices. Our decision path is based on the obvious criteria of power consumption and cost, but we also need devices that support the interfaces we need as well. There are a lot of devices to connect to an SoC, and the decision tree for finding the SoC that fits well is tricky (mainly because a lot of interfaces may be available, but muxed in a way that makes X unusable if you want to use Y, etc. In considering performance and cost, we want to look at processors that won't be shiny new when we have a product available, and won't be at the top of the performance curve then, either. The high-end SoC of last spring, when we got started, won't be the high-end SoC when a product is available. All of that led us to the Armada 610 product line. I can't really comment much on the Marvell Mobylize product pages - the one you linked to is one I've never seen before - and they're not really pertinent to what OLPC is doing. Marvell wants to get a lot of vendors using their SoCs in a variety of different ways, so they're motivated to have a variety of sample offerings. In fact, the tablet you pointed to claims to use the Armada 168 SoC, but when you look at http://www.mobylize.org/about the last question says: Which Marvell processors are being used with the Moby prototype? The Moby concept is based on Marvell's high-performance, highly scalable and low-power Marvell® ARMADA™ 610 application processor. Marvell is also making available a reference design for developing and testing applications. You can get Marvell's spec sheets on the Armada 168 and Armada 610 SoCs at: http://www.marvell.com/products/processors/applications/armada_100/armada_168/pxa_168_pb.pdf http://www.marvell.com/products/processors/applications/armada_600/armada610_pb.pdf - Ed P.S. I think I answered the touchscreen questions in my reply to Bert, but yes, we're also using the XO-1 case because that's what we have now. That saves many hundreds of thousands of dollars.

Re: XO-1.75 progress
Yes, the touchscreen is very important and is a complete gamechanger. The natural reaction for everyone is to try to use the screen as a touchscreen, especially children nowadays. Painting activites like colors are more natural and it becomes easier to use point-and click games/activities that don't use the keyboard with a touchscreen. Touchscreens are just so... natural, ergonomic and, usable. Here's another big, big, big thing with regards to schoolwork: With a touchscreen, you can draw diagrams doodles when taking notes which are essential in school + the creative process and are why laptops as they were cannot replace notebooks. It's a big shame the stylus for the XO-1 was never built and functioned. That would have solved it. Also, everyone here has to remember that despite the world going digital, penmanship is still a skill young children need to master, especially for every different culture - moreso chinese with its complex writing system. Writing is just too awkward with the touchpad. Did I mention drawing coloring is an important skill for young children? (I want to build a coloring book app - I can easily do it in Flash/AIR) If the stylus will still not be made to run on the XO-1.75, a touchscreen is a *must*-have. It's just broken without it and will make the machine a bit less relevant. IMHO it's better to delay the release of the 1.75 and force putting in a touchscreen. With the onslaught of cheap Android tablets coming from China, IMHO the next XO would be irrelevant to the public without it as it would offer no significant change outside the hood from the 1.5. There's just so many creative things app-wise one can do with multitouch :-/ That being said, congrats on the progress! -Naz Back in July there were plans to have a touchscreen in the XO-1.75: the XO-1.75 will have a touchscreen, as will future OLPC tablets based on its design http://lists.sugarlabs.org/archive/sugar-devel/2010-July/025376.html So this has been tabled? - Bert - -- carlos nazareno http://twitter.com/object404 http://www.object404.com -- core team member phlashers: philippine flash actionscripters http://www.phlashers.com -- poverty is violence ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Here's the thing though: The XO is now competing with the existing and growing slew of Android Tablets from China that cost $100 and under. Here's just one for example: http://micgadget.com/3210/the-cheapest-android-tablet-you-can-get-in-china/ Add to that the growing legion of Android developers - as I said before, OLPC needs to attract more 3rd party developers as it's still lacking apps. IMHO, something tablets cannot compete with that XO can do is the reconfigurable dual keyboard-touchscreen setup. Touchscreens are complete gamechangers, but for typing papers (and coding! I hope underprivileged kids grow up and start playing with code early!) - I think virtual keyboards are up to par yet. Although adding touch would significantly add to the cost, it will help developers get more used to and familiar the multi-touch paradigm. This way also, devs will be having huge familiarity with it once the XO-3 rolls out. Well, OLPC is still setting trends :) RIM/Blackberry is already starting to do a contributors' program: at Adobe Max 2010 (http://max.adobe.com), Co-CEO Mike Lazaridis announced that developers who get their Adobe AIR apps approved for the Blackberry App store would be eligible for free Blackberry Playbook tablets. Apps, apps apps! For Children, OLPC is competing with other platforms that have a growing library of kid-friendly apps. With regards to 3rd party developers, perhaps a wide press release making the contributors' program more visible might help? OLPC really, really needs more evangelism as sad to say, it has lost a lot of mindshare over the past few years due to FUD, and it really needs to be more competitive. Another thing I find sad is people raving on the different screen technologies like with Kindle its incredible sunlight readability when Pixel Qi much, much superior. OLPC needs to win more hearts and minds. I really don't think OLPC can win the price war anymore, so I think the focus should be building on and carrying on with its core strength of producing a superior innovative platform. Another big thing is the hackability, customizability ownability that corporate outfits like Apple will not let you do with their locked-down devices. Another food for thought: Whenever I bring the XO-1 with me and friends who have kids see it, first reaction is: I want one for my kid. Where can I get one? Sad part is that currently, the answer is You can't. I know that the G1G1 program had many problems, but the Philippines is so near to China Taiwan that customs + taxes aside, it would be ridiculously easy logistics-wise to ship units here compared to the U.S. and Europe. G1G1 would not be feasible here though, because it's really too expensive for people who can pay here. Would it be possible to do a small available to consumers Buy 1 Get 1 (B1G1) pilot here for a cost + some margins to help support OLPC program? A big help to evangelize OLPC would be to actually get people to experience it and own it. Another thing that's completely wrong: Reverse-gadget envy - that underprivileged kids public schools can get something for free that taxpayers pay for when governments shell out for XO units, and yet tax-paying citizens cannot get their hands on them and provide them to their own kids. I think it's also sad and wrong for OLPC to just surrender a big audience demographic to other netbook makers as some people here in the list have suggested because the XOs still pack features that are unavailable with other platforms. These can be remedied, right? I love OLPC and the platform it provides. I want it to succeed and keep leading the revolution. I hope I didn't offend anyone, but this is insight coming from a member of a third world country where poverty is a big big problem and ordinary citizens struggle to make ends meet.

XO-1.75 progress
Hi all, OLPC Engineering had a trip to Taipei for the XO-1.75 motherboard bringup last week. The 1.75 machine lives in the same industrial design (display, case, batteries) as the XO-1/XO-1.5, but uses an ARM system-on-chip from Marvell -- the Armada 610/MMP2. There's still a great deal of driver and basic bringup work ongoing, but we're at a point where we can share details and photos: http://wiki.laptop.org/go/XO_1.75_A1 http://wiki.laptop.org/go/XO1.75_Bringup http://wiki.laptop.org/go/File:XO1.75_A1_bringup.jpg http://dev.laptop.org/~lennert/20101109148.jpg http://dev.laptop.org/~lennert/20101108144.jpg http://dev.laptop.org/~lennert/20101108146.jpg http://dev.laptop.org/~cjb/1.75/1.75-a1-dmesg http://dev.laptop.org/~cjb/1.75/xo-1.75-broughtup.jpg The grand plan is to first move to the new ARM motherboard in the old industrial design (XO-1.75), then move to that same motherboard in a new tablet industrial design (XO-3). Of course, there tend to be a lot of changes to OLPC's grand plans before devices ship! Software-wise, we're running XO-EC and Open Firmware at the low level, and Fedora 12 with Sugar and GNOME for the OS. We plan on moving up to Fedora 13 or 14 as they become available for ARM. (An easy way to help us out would be to help the Fedora ARM team with their mass rebuilds for newer Fedora releases.) As usual, we'll be running a Developers Program with these machines once we've got past the necessary initial hardware fixes and made a larger volume of boards. That's going to take several months, but we wanted you to know that it will be coming.

Of course, there tend to be a lot of changes to OLPC's grand plans before devices ship! Software-wise, we're running XO-EC and Open Firmware at the low level, and Fedora 12 with Sugar and GNOME for the OS. We plan on moving up to Fedora 13 or 14 as they become available for ARM. (An easy way to help us out would be to help the Fedora ARM team with their mass rebuilds for newer Fedora releases.) As usual, we'll be running a Developers Program with these machines once we've got past the necessary initial hardware fixes and made a larger volume of boards. That's going to take several months, but we wanted you to know that it will be coming.

I notice in the dmesg printout that the BogoMips for this initial XO-1.75 version is less than for the G1G1 XO-1. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: XO-1.75 progress
Hi, I notice in the dmesg printout that the BogoMips for this initial XO-1.75 version is less than for the G1G1 XO-1. BogoMIPS, of course, being the ultimate measure of CPU performance.. The most obvious reason why this isn't a meaningful comparison, which isn't to say that there aren't many more, is that we're now using a dual-issue CPU. - Chris. -- Chris Ball c...@laptop.org One Laptop Per Child ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
