Hello, For a project I'm searching some low cost hardware that is EFL compatible. Spec: - flat board possible to mount on back of (included) display (~5-8) - supports Linux (or any other opensource OS) - supports EFL or possible to port without big efford - X or framebuffer output for one single fullscreen process - fanless - low power needs - touch screen (optional) - enough memory to run OS + EFL + small application - less CPU usage needed (enough for simple animations) - runs OS from flash - USB or SD card support - sound output (optional) - hardware possible to buy as prototype and at larger numbers Maybe think of some digital image frame hardware or some PNA (navigation) hardware but I need it for another usage. All what I found was not tiny enough from board size and offered better (more expensive) hardware than I need. As I know some of you are working with EFL on embedded hardware maybe someone has an hint for me. For sure this hardware needs to be cheap! regards Andreas -- Technical Blog http://andreasvolz.wordpress.com/ -- AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on Lean Startup Secrets Revealed.

He did not mention that either, in fact what he did mention seemed to go in the opposite direction - depends if he includes scrolling with animation. a lot of people don't. for efl scrolling and animation is the same thing. it's all re-rendering. - flat board possible to mount on back of (included) display (~5-8) - X or framebuffer output for one single fullscreen process - enough memory to run OS + EFL + small application - less CPU usage needed (enough for simple animations) snip All what I found was not tiny enough from board size and offered better (more expensive) hardware than I need. Don't sound like he's wanting to do much high resolution or high speed rendering. Sounds more like my current project. Sometimes a slow processor, with minimal RAM, and software rendering on a simple frame buffer are all you need. If, as you say, gl is that much work, then he would need to consider if he actually needs it, not just let it go without saying. Same with me, I did not need X, I did not need GL, I don't even need directFB so those are things I do not have to worry about for my project. It's all working fine on software driven fb with much less effort. it all depends on what your final target experience is meant to be. The older generation of gumstyx might work for him, it comes with E17 as the default window manager, so you know it runs EFL and Linux. Only reason I'm not using those in my current project is that the client wanted VGA output. Just like Andreas, my client is having a hard time sourcing stuff that is not just way overpowered for the application. that's pretty much part of the game. if you want to order in large quantities - you can get just about anything. small quantities == you have to piggyback off excess volume and that generally either means obsolete stock someone hasn't dumped yet, or something recent thats out and in the mainstream and hasn't been passed up yet in favor of the next best thing. probably the only socs i know u can find readily these days that are not the cortex-a8 land (gumstix as u mention) might be the older pxa or s3c64xx ones - those are now pretty much on the get rid of stock list i'd think - or close to it. the gumstix verdex (pxa270) is about as old school as u get now in easy to find volume. and its a mere $20 less than the omap 3503 overo which gets you a significantly faster SoC. you're talking $150 vs $130. you seriously aren't going to get a hell of a lot cheaper unless you make your own boards, and then you'll have to pay for the board design, production runs etc up front so you'll only come out cheaper if your volume is up there. only thing i know of that might be cheaper is finding an already mass-produced device (gumstix arent mass-production really, though cool and awesome) and strip it down. chances are u will find it around a similar price range, BUt you'll get a screen, battery and other bits too. e.g. this: http://phandroid.com/2010/03/02/below-100-hivision-speedpad-android-tablet/ for $100 you get a s3c6410 (its going to beat the fastest pxa270 gumstix has at 600mhz as it'll clock in at between 800mhz AND has an opengl-es2 gpu in there too - thus why i ask about the opengl stuff). now let's compare the CHEAPESt thing gumstix has: gumstix vs speedpad price: $129 vs $99 speed: 400mhz vs 800mhz ram: 64m vs 256m storage: 16m vs 2048m camera: n/a vs yes screen: n/a vs 7 800x480 + touch battery: n/a vs yes (4200mAh 6hrs) wifi: n/a vs 802.11b/g i'm not saying that he should go for this, i'm just saying that... a ready-made product is already cheaper than a bare bones board. i'd
