Even though OpenMoko strives to keep the community informed of the development progress, OpenMoko does not provide delivery dates. Instead, OpenMoko reports the project status here and on the openmoko-community mailing list.

The status is usually updated at least twice a month, usually by Michael Shiloh. Updates are also mailed to the community mailing list (see below for previous updates), and major updates are also sent to the announce list.

You are invited to add questions or topics you think should be included in the Community Updates.

The latest Community Update was posted to the community mailing list on January 10.

Discussion of current issues

GTA01 Advanced Kit price reduction

12/20/2007 - We have dropped the price of the GTA01 Advanced Kit from $450 to $399. I'm pretty sure that's effective immediately and should be reflected at our web store right now.

The price of Base Kit remains the same.

GTA02 hardware design and test

The information below has been collected from various sources, feel free to add questions and comments here.

While writing a device driver for the new battery which provides an accurate counter of the charge state of the GTA02, the driver developer discovered that the device driver does not get a reading of the charge state due to a very long response time with only one I/O signal when trying to read the charge state. To be able to read the battery status properly, it has been written that it will be necessary to re-design that part of the GTA02 for hardware version GTA02A5 to use two I/O signals to reduce the response time (one for transmitting commands, one for receiving data?). Bug 957 may have more information.

12/06/2007 - GTA02a5 is a minor variation from GTA02a4, so it shouldn't take very long. We are waiting for confirmation of Wifi and a few other parts of the GTA02a4 hardware before we manufacture even a small test run of GTA02a5.

gllin GPS driver for GTA01

11/29/2007 - Thanks to a tremendous amount of hard work by many people, we have ready a release of gllin, the GPS drives. Instructions at [1] or grab the ipk directly from [2].

850 MHz band not supported in USA+Canada (e.g. comment 24 on bug #256)

The GSM chip set is capable of quad band operation but the circuit implemented in GTA02 only supports 3 bands. Currently GTA02 supports only 900/1800/1900MHz.

11/29/2007 - We would like to offer an 850/1800/1900MHz version of GTA02 for areas that need it. We are looking into whether this is feasible or not. This requires a number of changes (components, firwmare, calibration, etc.) and so is uncertain until we test it.

12/09/2007 - Since the GSM section is essentially the same between GTA01 and GTA02, we thought a good experiment would be to modify a couple GTA01 handsets for 850MHz and to test them out here in the USA.

12/20/2007 - Due to the enthusiastic response I received to my request for testing volunteers I've asked our hardware group to modify a few more phones. I don't know when, or even if, they will be able to do this. Meanwhile, I'll be sending out the units I have to the testers, along with a simple test plan.

We have no intention of manufacturing 850MHz GTA01s, nor can we modify user's phones this way. We modified a couple of units ONLY so that we could test the circuit that we might use in GTA02. When the experiment is done, these modified units must be returned to OpenMoko.

Conversion of GTA02 to quad band would require major changes and so will not happen.

Delivery of a GSM firmware update for the 3G SIM bug (#666)

Background:

A bug in the GSM firmware prevents some USA 3G SIM cards from working properly. The bug has been fixed, but since the GSM module is under extremely tight legal protection, it is not clear whether or how we can allow customers to perform this upgrade themselves.

12/09/2007 - We've been informed that everything legal has been agreed upon by all parties regarding the process that would allow you to upgrade your own GSM firmware. All that remains is to get everything signed. Apparently the process of getting things signed takes a few weeks!

12/20/2007 - Meanwhile, we have resolved the difficulties I was having performing the upgrade, and I am now able to upgrade your handsets. Anyone interested in having me do this should contact me at michael@openmoko.org.

Questions or Topics you think are missing

SMedia 3362 Documentation & OpenGL ES Drivers

There is an open source kdrive driver being written for the GTA02 which will use hardware to accelerate the XRender extension. While the chip is capable of 3D graphics, no OpenGL ES driver/library is avaliable and OpenMoko developers will not be writing one in the near future (although they have not ruled it out in the long-term).

Documentation for the SMedia 3362 has been promised (see this post). However, this refers to documentation OpenMoko developers will be writing themselves, not the technical documentation SMedia have provided OpenMoko with. The OpenMoko developers had to sign an NDA with SMedia to obtain this documentation and are therefore unable to pass this information on to community developers. (See this post for details)

Power Management on the Neo1973

It is still not clear if it will be possible to have "reasonable" battery life on the Neo1973 (GTA1) hardware or if there are hardware problems that make this impossible.(see this post). Can this be officially clarified.
