<br>> Hi all,
<br>> I have good news and bad news. As usual,
<br>>
<br>> a) good news first:
<br>>
<br>> the DM3730 CPU is working fine :)
<br>>
<br>> We had to fix some PinMux settings and initialisation
<br>> in X-Loader and U-Boot, but yesterday I received the
<br>> first board with a UMTS module!
<br>>
<br>> <a href="http://download.goldelico.com/gta04/images/DSC00977.jpeg">http://download.goldelico.com/gta04/images/DSC00977.jpeg</a>
<br>>
<br>> This board has all components as the final GTA04.
<br>>
<br>> b) bad news:
<br>>
<br>> the UMTS module does not respond on
<br>> the internal USB2.0 :(
<br>>
<br>> It is not even clear if it is initializing and running its firmware.
<br>>
<br>> Currently we have no idea why and have not found
<br>> a way to debug it. What we don't know is, if we did some
<br>> mistake in hooking it up to the CPU or if it was badly
<br>> soldered or even was damaged during soldering.
<br>>
<br>> This crumbles up the schedule again :(
<br>>
<br>> The plan was to have this "golden master board" working
<br>> by yesterday and then produce the Early Adopter boards
<br>> next week.
<br>>
<br>> But we can't start production before we know what the
<br>> problem is. Unfortunately, the production company will
<br>> have 3 weeks of holidays after next week. So unless we
<br>> find a solution over this weekend, we will have to wait until
<br>> end of August :(
<br>>
<br>> One test we can do on Monday is to solder some wires directly
<br>> to another module. I.e. we don't reflow the whole module and
<br>> have more access to all signal pads.
<br>>
<br>> But it is not clear if this already breaks the schedule. And
<br>> experiments like this also strain our development budget.
<br>>
<br>> Well, the budget already became quite low due to all these
<br>> delays and many reworks.
<br>>
<br>> So I would like to ask for some financial support. One option
<br>> is to donate:
<br>>
<br>> <a href="http://www.handheld-linux.com/wiki.php?page=GTA04-Early-Adopter">http://www.handheld-linux.com/wiki.php?page=GTA04-Early-Adopter</a>
<br>>
<br>> (at the bottom of the page "Just a donation...").
<br>>
<br>> Another good help would be if you could consider buying or
<br>> recommending this nice MIPS based mini-book from our shop:
<br>>
<br>> <a href="http://www.handheld-linux.com/wiki.php?page=Letux%20400">http://www.handheld-linux.com/wiki.php?page=Letux%20400</a>
<br>>
<br>> It is not the most modern one, but amongst the cheapest ones and
<br>> with 670g really light weight. Some guys also have a working 2.6.31
<br>> kernel for this machine so that Debian Squeeze can run.
<br>>
<br>> We can also provide the schematics so that you can e.g. add
<br>> an external access to the I2C bus or whatever ideas you have.
<br>>
<br>> Getting rid of the remaining stock without scrapping them would
<br>> contribute a little to the GTA04 project.
<br>>
<br>> Sorry that I don't have good news only,
<br>> Nikolaus
<br>>
<br>>
<br>> PS: if someone is interested in internal details of the UMTS module
<br>> (which appears to be the same chipset as used in the iPhone 4),
<br>> start to search the web for "Gobi 3000" or "MDM6200". Or go to
<br>> <a href="http://transition.fcc.gov/oet/ea/fccid/">http://transition.fcc.gov/oet/ea/fccid/</a>
<br>> and search for NCM / OMO6012
