[:BuildingCommunity/TeamReporting:Back to the Team Reporting page...]

Welcome to the MobileAndEmbedded reporting page. Every month this page reveals a snapshot of the work that has been going on in the Ubuntu Mobile and Embedded Community. If you have have been working hard on the project and want to let others know what you have been up to, try to summarize it here. Community contributions are actively encouraged. A few guidelines for how to write good points are:

  • Keep it simple and short - single sentences are best. Smile :)

  • Try to summarise your work and not be over-detailed - we don't need to know specifics, just a summary of the kind
  • Where possible, include relevant links.

You should get all your reporting included here by the 22nd of every month.

Ubuntu Mobile [ MootBot Logs]

Status report for week 2007-10-25 to 2007-11-01

Midbrowser status update

  • Mostly working on bug fixes.
  • Analyzed a few sites that didn’t work quite right with Midbrowser. Among them are Microsoft’s * Those sites didn’t behave correctly because they didn’t think Midbrowser is not one of the supported browsers (Firefox, Netscape, IE). It turns out that by setting the useragent key to Firefox, these sites work just fine. I will put a fix in for that. We also found out that couple of the sites didn’t work because of bug in Adobe’s flash player for Linux. I contacted the owner of the sites and confirmed that.
  • A patch to enable the “pref” extension in the browser is ready. Waiting further code review from Asac and will check the changes it.

USB Client Status

  • Use case:
  • MID is already turned on; plug the MID directly into my PC via USB cable
  • MID's data (videos, music, photos, etc) are visible in the file manager on my PC. They appear on the PC as either as separate volumes or as directories in a single volume
  • Using the file manager on the PC, add/remove files on the MID
  • Unplug the MID from the PC, enjoy the movie I just copied to it It's our understanding that Intel is supporting this case through the file-backed storage gadget. Some questions:

    1) Is Intel patching the file-backed storage gadget to expose the client's ext3-formatted filesystem to the host as a FAT filesystem (requiring ext3<-->FAT translation[1])? If not, what is the plan to expose files

    • contained by that FAT image to applications on the MID?
    2) Consider the case where I have a MID with 4GB total storage, and I want to copy a 2GB movie to it. How will the file-backed storage gadget handle this situation? The MID doesn't have enough storage for 2 copies of the movie (one in the FAT image and one in the MID's native ext3 filesystem). 3) The blueprint and your status report both mention host-side utilities. Are those utilities required for file sharing, or are they used exclusively for sharing the MID's network connection? 4) The blueprint and your status report both mention Samba for file sharing/transfer. How is Samba relevant to USB Client? When plugged into a PC via USB, will the MID appear as a network share? If so,
    • will it also appear as a FAT device? Why present the user that choice?
    USB Client external availability still November 5, 2007 USB Client Features, from internal release note: Drivers:
    • 1) Support USB2.0 spec to enable Poulsbo USB client hardware. 2) Support USB Mass Storage class to expose mass storage device. 3) Support USB CDC-EEM class and RNDIS spec to expose Ethernet device. 4) Support interoperation with both Linux an Windows host PC of
      • VFAT/FAT32 file systems in mass storage device condition.
      5) Support interoperation with both Linux and Windows PC with
      • CDC-EEM/RNDIS compatibility.
    • 6) Utility automatically start DHCP server to allocate IP addresses in
      • host and client if static IP is not chosen.
      7) User can specify directories to share with host through GUI utility. 8) Samba server is automatically started in client utility to share
      • selected folders.
      9) Shared directories will be shown in a GUI Window. 10) User can set different access permissions to each samba user.
    Known issues:
    • 1) Drivers are not tested in High-Speed environment due to some known
      • HW sightings and bugs in Poulsbo B0 board.
      2) Drivers don't pass USB-IF Compliance test. There are some potential
      • bugs about:
        • a) USB reset, Power Management b) GET_STATUS, CLEAR_FEATURE, SET_FEATURE USB standard control requests
      3) File-backed storage (MSD) gadget doesn't support endpoints STALL feature now,
      • set module parameter "stall=0" can work.
      4) USB VID and PID for MSD and RNDIS gadgets are temporary ones. 5) The solution of static IP option is under discussion and not finalized now. 6) The interaction of Linux client utility and Windows host utility are not verified. 7) Client utility sometimes is aborted when new share folder is added.

Mobile build infrastructure

  • No progress. Publishing of proprietary builds is blocked on IS (ticket filed). Gutsy + updates is also blocked, pending IS to set up lpia PPAs. Other news:

    Pre-alpha was released on Monday 22 October: for more information.

Hildon Desktop Status

  • Finally fixed hildon-desktop; apart of the issues already covered here, only a configuration issue remained
  • Merged or checked that we did merge misc stuff which Bob asked me to have in our hildon-desktop
  • Fixed the stamp issue I encountered last week
  • Checked that an old ~/.osso would still work with newer hildon-desktop; please note that we're condemned to perpetual backward compatibility with whatever ends up in the ~/.osso of end
    • users in the next versions...
  • Updated mobile-image-creator in hardy; we now use lpia in Ubuntu's mic by default
  • Misc fixes and uploads

Moblin-applets status

  • Held a review of the moblin-applets feature set through the moblin mailing list and the overwhelming response was that we have way more features than we need. Thus, this week I've been chopping the applets down to the bare minimum of features for use on a mobile device. Also am working on the creation of a ventral libmoblin-dev and libmoblin runtime library that applications and applets can use to get the up-to-date list of all the gconf keys and their settings that we use, and am working to add in macros for icon and desktop theme functions that mirror their gtk equivalents.

midbrowser status

  • Continued bug fixes.
  • Attempted to build Midbrowser with Intel C/C++ compiler (10.0 beta). There were a lot of complain about performance. We wanted to see if using Intel’s C/C++ compiler will give us any performance boost.
    • From past experience, this should give us > 10% performance improvement. Unfortunately the Compiler has a bug and Midbrowser binary crashed. The Compiler team has identified the cause and as soon as I get a patch from them, I will give it a try again.

  • We are attempting a build of Midbrowser with Firefox 3.0 base code. We should have a successful build sometime today.
  • I am also looking into using larger icons in the URL bar. They are just too small.
