  • Development process for an embedded project with significant hardware changes

    - by pierr
    I have a good idea about Agile development process but it seems it does not fit well with a embedded project with significant hardware changes. I will describe below what we are currently doing (Ad-hoc way, no defined process yet). The changes are divided into three categories and different processes are used for each of them: complete hardware change example : use a different video codec IP a) Study the new IP b) RTL/FPGA simulation c) Implement the legacy interface - go to b) d) Wait until hardware (tape out) is ready f) Test on the real hardware hardware improvement example : enhance the image display quality by improving the underlying algorithm a) RTL/FPGA simulation b) Wait until hardware and test on the hardware Minor change example : only change hardware register mapping a) Wait until hardware and test on the hardware The worry is it seems we don't have too much control and confidence about software maturity for the hardware changes as the bring-up schedule is always very tight and the customer desired a seamless change when updating to a new version of hardware. How did you manage this kind of hardware change? Did you solve that by a Hardware Abstraction Layer (HAL)? Did you have a automatic test for the HAL layer? How did you test when the hardware platform is not even ready? Do you have well-documented processes for this kind of change?

  • Failed install 12.04 on Intel Hardware Raid with Large Partition (> 2TB)

    - by Michael Wiles
    I have Intel Hardware Raid on the motherboard. I have 10 2 TB HDD that I've configured as RAID 1+0 to be one big 8 TB HDD. Now I'm trying to install ubuntu 12.04 on it. After installing with default desktop installation disk I get a blank screen with a cursor flashing. If I try the alternate guided partitioning option I get error: out of disk. and the grub prompt. If I boot with the rescue disk or such like I can drop into a shell and view the disk. Everything also installs without an issue. Don't know what to do...

  • Developing a DVR software using a hardware KIT

    - by Leron
    I'm currently thinking about a project for my masters degree graduation. I start researching for options to make my own video streaming software based on a premade hardware kit having not much knowledge about what I'll exactly need that will match my needs. My search led me to the DVR (Digital Video Recorder) cards which seems to be the closest to what I need, but still I can't find out a few basic things so I decide to ask for them here. Currently I haven't find a lot of manufacturers that offers such kits so where I can look and have some options to choose from? There are a lot of DVR products on the market but they already have a software written for them and even if I buy one they just don't give any documentation or sdk's so buying such is not an option I need a DVR card made exactly for software programers and not end users. Are there a preferred manufacturers that provide such kind of devices with good and developer-friendly documentation? Also - I prefer to do all this with Java, is this an option (I think I will make it with .NET too but really prefer Java as a language of choice)

  • Ruby SerialPorts Gem

    - by Seth Archer
    Using Ruby SerialPorts Gem to interact with hardware. When I write a byte array to the hardware using a program called "Serial Port Monitor" the hardware responds correctly. However, when I write the same byte array using ruby it doesn't work unless I do a read request just before the write request. This device doesn't respond correctly with this sp = SerialPort.new(args) sp.write [200.chr, 30.chr, 6.chr, 5.chr, 1.chr, 2.chr, 0.chr, 244.chr] But it does if I add a read request before the write. Like this sp SerialPort.new(args) sp.read sp.write [200.chr, 30.chr, 6.chr, 5.chr, 1.chr, 2.chr, 0.chr, 244.chr] This works, but I'm at a loss as to why. I should also add that the first snippet does work occasionally maybe 1/10 of the time.

  • Where to find information about ubuntu compatible or certified hardware/PC models

    - by Halkinn
    I am buying a new desktop PC in early 2013, anyway this question should apply to someone intending to buy a new laptop/ultrabook as well. This machine is not meant for gaming, and if I ocasionally do it, I can survive with minimum graphics. However I may need some heavy multimedia edition or multitasking at times, so basically my greatest priority is a good processor, after that perhaps average graphic card (if onboards are not enough, I am still not informed enough about that), at least 4GB of RAM with possibility of expansion. I know there are some PC models specially designed to ship with Ubuntu, which is the OS I use the most these days. However, most people around me use Windows and some software with unsupported versions for Linux and not having a Windows license becomes a bit problematic. Given that, I would like to find information about which PC models or even manufacters currently on the market have the best compatibility with Ubuntu, I am still undecided between building my own desktop or buying a pre-made model, so I would like to find information both for certified models and certified hardware or even Ubuntu partners that may work closely with Canonical. Where to find this information in order to make sure that I will have a good experience with Ubuntu on my new PC in the years to come?

    When I edit system files, for example when I edit rules for my trackpoint using this command: gksu gedit /etc/udev/rules.d/trackpoint.rules I get the following errors in the terminal (after closing gedit and saving the file): error: line 10034: 0 is wrong flag id error: line 10034: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 19814: 0 is wrong flag id error: line 23363: 0 is wrong flag id error: line 23363: 0 is wrong flag id error: line 26005: 0 is wrong flag id error: line 26005: 0 is wrong flag id error: line 26846: 0 is wrong flag id error: line 26846: 0 is wrong flag id error: line 28718: 0 is wrong flag id error: line 31695: 0 is wrong flag id error: line 31695: 0 is wrong flag id error: line 35272: 0 is wrong flag id This goes on up until line 150400. The changes are applied as desired, but can somebody explain the error to me as I'm a newbie and just trying to get a clue about the terminal.

  • Recommended hardware for developing ios games?

    - by Matthew
    I know you have to have mac os x to use xcode and thus to develop/compile apps for the iphone. And I'm not exactly wanting to go the hackintosh way, so I'm looking at buying a used mac. What specs are recommended. If I buy a cheap mac mini that has only 1gb of ram would that be enough? (I'm not talking about using that to create the graphics/audio, I'll use my normal windows/ubuntu pc for that). I'm just talking about being able to use xcode and write applications. I'm trying to spend the least amount I can without running into problems developing the app.

  • Hardware issues on Samsung NF208 (NF210)

    - by KristoferA - Huagati.com
    I'm trying to get Ubuntu 10.10 running on my wife's Samsung NF208 (same spec as NF210, but shipped without OS), and I have run into a pile of problems: At first, there were problems with audio, display brightness, and WiFi, so I reinstalled Ubuntu from scratch. After reinstalling, the audio has started working but the WiFi loses network access all the time and then it takes 5-10 minutes for it to reconnect to the network. Also, display brightness is at its lowest. I have tried to use the brightness command but it won't run. Is this system utterly incompatible with Ubuntu, or are there working WiFi and display drivers for it somewhere? I have googled for days but haven't found anything useful. Help me. Update: I never got it working properly. I came across lots of useful tips and tricks over at the forum linked to in the accepted answer but I just wasn't able to get it working and stable enough for the intended use. Hopefully a future version of Ubuntu and/or the samsung tools will solve that. Related thread over at the other forum: http://www.voria.org/forum/viewtopic.php?f=3&t=682

  • Lenovo Thinkpad X1 Carbon support

    - by Robottinosino
    I am considering selling my Mac to get money towards a Lenovo Thinkpad X1 because what I really want to do is to be running an Ubuntu system all the time. Is this machine completely supported in Ubuntu, with no tiny little feature missing just because I am "going Linux"? Optional user story section, skip to the question below if you don't have time: I have a friend who bought a "works on Ubuntu" system a year ago and has hated the fact ever since: battery lasts less than if he boots in Windows (which he despises) and he ascribes that to "no good OS/harware integration and support for advanced chipset power management features", odd behaviour on suspend/resume/hibernate (says: "when it works 90% of the time and the other 10% it makes you lose your work is as good as broken - 90% is the same as 0% he says), some occasional graphics card glitches he can perfectly well live with and has almost grown affectionate to, and finally, and that is what would make him undo his choice if he could, bad "input device drivers". He says: trackpoint and trackpad just "feel different", "so much better" on Windows and that was impossible to know from the website brochure. That story makes me very doubtful... but I want to abandon this "walled garden" of prison that is my Mac and go Ubuntu all the way, no doubt about that! My dilemma at this time is just: "I don't want to live with those eternal frustrations for sure"! Here's a directly answerable phrasing of my question: Is the Lenovo Thinkpad X1 supported on Ubuntu? Yes/no, which version? Which hardware features are not supported? Provide a list Optionally: sort the list in descending order of frustration from your experience Optionally: mention if there are acceptable workarounds to the "out-of-the-box" condition described in the earlier points and whether this ameliorates frustration at least to "tolerable" levels Comment: the Ubuntu hardware certification page is so not-for-end-users it's unreal. Whoa. What would make it end-user friendly is: Link to "buy here and you'll be just fine, this is the right configuration for you, it'll work as long as you press BUY on that page and don't browse further" Remove mentions of may and might not work. Just tell it straight: press buy here and you will get a working system with the exception of A, B, C (so that I can decide whether the philosophical "freedom pleasure" I get from escaping an Apple world is enough to off-balance the loss, for instance, of Bluetooth capabilities (something that I of course use on my Mac) but "could" lose to use free (as in freedom) software The certification page fails to dispel doubts in me as an end-user. I don't feel "eased into Ubuntu", I feel "partially informed".

  • Java Hardware Acceleration

    - by Freezerburn
    I have been spending some time looking into the hardware acceleration features of Java, and I am still a bit confused as none of the sites that I found online directly and clearly answered some of the questions I have. So here are the questions I have for hardware acceleration in Java: 1) In Eclipse version 3.6.0, with the most recent Java update for Mac OS X (1.6u10 I think), is hardware acceleration enabled by default? I read somewhere that someCanvas.getGraphicsConfiguration().getBufferCapabilities().isPageFlipping() is supposed to give an indication of whether or not hardware acceleration is enabled, and my program reports back true when that is run on my main Canvas instance for drawing to. If my hardware acceleration is not enabled now, or by default, what would I have to do to enable it? 2) I have seen a couple articles here and there about the difference between a BufferedImage and VolatileImage, mainly saying that VolatileImage is the hardware accelerated image and is stored in VRAM for fast copy-from operations. However, I have also found some instances where BufferedImage is said to be hardware accelerated as well. Is BufferedImage hardware accelerated as well in my environment? What would be the advantage of using a VolatileImage if both types are hardware accelerated? My main assumption for the advantage of having a VolatileImage in the case of both having acceleration is that VolatileImage is able to detect when its VRAM has been dumped. But if BufferedImage also support acceleration now, would it not have the same kind of detection built into it as well, just hidden from the user, in case that the memory is dumped? 3) Is there any advantage to using someGraphicsConfiguration.getCompatibleImage/getCompatibleVolatileImage() as opposed to ImageIO.read() In a tutorial I have been reading for some general concepts about setting up the rendering window properly (tutorial) it uses the getCompatibleImage method, which I believe returns a BufferedImage, to get their "hardware accelerated" images for fast drawing, which ties into question 2 about if it is hardware accelerated. 4) This is less hardware acceleration, but it is something I have been curious about: do I need to order which graphics get drawn? I know that when using OpenGL via C/C++ it is best to make sure that the same graphic is drawn in all the locations it needs to be drawn at once to reduce the number of times the current texture needs to be switch. From what I have read, it seems as if Java will take care of this for me and make sure things are drawn in the most optimal fashion, but again, nothing has ever said anything like this clearly. 5) What AWT/Swing classes support hardware acceleration, and which ones should be used? I am currently using a class that extends JFrame to create a window, and adding a Canvas to it from which I create a BufferStrategy. Is this good practice, or is there some other type of way I should be implementing this? Thank you very much for your time, and I hope I provided clear questions and enough information for you to answer my several questions.

  • Trouble with local id / remote id configuration of VPN

    - by Lynn Owens
    I have a NetGear UTM firewall and a Windows machine running NetGear's VPN client. The Windows machine I can put on the UTM network and take off of it. When I am cabled into the local (internal) the following configuration works: UTM: Local Id: Local Wan IP: (The UTM's WAN IP address) Remote Id: User FQDN: utm_remote1.com Client: Local Id: DNS: utm_remote1.com Remote Id: (The UTM's WAN IP address) Gateway authentication: preshared key Policy remote endpoint: FQDN: utm_remote1.com But when I'm off the UTM's internal local network and simply coming in from the internet, this does not work. It simply repeats SEND phase 1 before giving up. Since I know that the UTM WAN IP is accessible from both inside and outside the network, I figured the problem was with the Client local id. So, I tried the following: UTM: Local Id: Local Wan IP: (The UTM's WAN IP address) Remote Id: (A DN of a self-signed certificate I created for the client and uploaded into the UTM certificates) Client: Local Id: (The DN of the aforementioned self signed cert) Remote Id: (The UTM's WAN IP address) Gateway authentication: (the aforementioned self signed cert) Policy remote end point: ... er, ... my choices are IP and FQDN.... Not sure what to put here No matter what I've tried, it just keeps repeating the SEND phase 1. Any ideas?

  • Who makes laptops for Ubuntu?

    - by Tim Lytle
    I'm looking for a laptop and would like to avoid the whole 'is this [specific configuration of hardware] compatible with Ubuntu?' process by finding a laptop manufactured with Ubuntu in mind. I know of system76, but are there any other manufacturers making laptops built to run a standard build of Ubuntu? I'm not counting Dell, as - from my experience - their 'Ubuntu' laptops/netbooks require their build, and because of that have their own set of compatibility issues. UPDATE: And as mentioned in the comments, Dell is no longer selling systems with Ubuntu to consumers.

  • Remove hardware from "safely remove hardware" list on Windows 7

    - by ricsmania
    Hi, I have a USB wifi card (D-Link DWA-125) on a Windows 7 x64 computer. The problem is that the card appears on the "safely remove hardware" list, but I don't ever want to unplug it, so I would like to remove it from the list. So far I have only found solutions that mess with the registry (and don't really work properly) or that substitute the safely remove hardware with a third-party software. Or worse, hide the icon altogether. Yes, I do need the icon from USB drives and phones. So, is there a "clean" way to remove it from the list? Thanks.

  • Web App Server hardware question. Which configuration?

    - by JBeckton
    I am pricing some new servers and I am not sure which configuration to get. The server will be running several web applications for our company. Some of them are ASP.Net sites and some are ColdFusion. The OS will be Win Server 2008 Web or Standard Edition. Do I need 2 processors or will a single quad core handle it? Xeon multi core Hyperthreading or non Hyperthreading? I am going 64bit so I can go higher than 4 Gigs of Ram. I am shopping at Dell and there are so many options, I want to get the most bang for my buck without going over budget and I also don't want the machine to be mostly under utilized.

  • Hardware Acceleration on Windows Server 2008

    - by user1184598
    Does Windows Server 2008 have hardware acceleration? I tried to use WPF to make over 20,000 drawings. It only cause around 40% CPU in windows 7. However, I run the same program on Windows Server 2008 with the same hardware configuration except that it has a dedicated graphical display card (GT 9500) while Windows 7 has only an onboard display card, it cause over 80% CPU. So, does Windows Server 2008 have hardware acceleration? Or could I make it? And how do I change the hardware acceleration setting? Thanks.

  • hardware for pushing buttons

    - by Elazar Leibovich
    Many times I want my computer to interface old hardware. Such as radio, light switch, etc. This mostly involves pushing pressing and moving various buttons and switches. I don't want to buy new hardware I want my computer to interface the old hardware I already have. I thought about it and reached to the conclusion that what I need is a general purpose button-pusher hardware. I need a simple device I can interface by a computer and would be able to push most of the buttons we have in daily accessories, without damaging the button. Is there any such accessory availible?

  • Server Hardware on the Desktop

    - by jcnnghm
    When I rebuild my desktop, I'm thinking of using server hardware instead of desktop hardware. I want to do this so I can easily add a lot of ECC memory (~20GB), and possibly more than one processor. I know that video hardware could be a problem, especially because I use 4 monitors. I should be fine with this, as long as I have two pci-e channels. Are there any downsides to doing this? Anything I'm not seeing?
