Hi, it seems that the nokia express music 5610 (in the forum they say "nokia exper muzic 5610") uses this kind of chipset (mt6226) and from the source the mt6227 is the same(?) and when I search for that I get many results. bjoern -----Ursprüngliche Nachricht----- Von: baseband-devel-bounces(a)lists.osmocom.org [mailto:baseband-devel-bounces@lists.osmocom.org] Im Auftrag von Harald Welte Gesendet: Montag, 12.

Ok. I only did a quick search on google.. But this phone uses the mt6223 chipset: "lenovo 688" It is quite ugly with hello kitty design but has a big screen and is available on ebay.

Hi,all Most phones made in china are using MTK platform.MTK platform is very cheap and highly integrated！ You can download more data or tools here: * ftp://study-bbs.com:study-bbs0304@220.113.15.15* Directory names and file names are in chinese,but most datasheets are in english. I'll give you some hints for understanding these chinese words. At the home directory of this ftp account,it may looks like this: / PADS2007视频教程光盘及试用版 //A video tutorial of a PCB design software max //unknown(maybe related to WinCE) 创易电子资料 //unknown 华禹-下载说明.txt //the same as "readme.txt" 实用单片机系统 //something about SCM 旋风001手机模块 //plese entering this directory!MTK related!

Hi Wolfgang, On Tue, Apr 13, 2010 at 12:40:39PM +0000, Wolfgang Spraul wrote: thanks a lot for your feedback and input. You can find the MTK reference schematics easily online - but not the various actual products that Chinese manufacturers build based on them. So those books are probably a really good idea. yes, JTAG would be incredibly cool. I really don't understand why the study-bbs.com P1302 and P1300 are sold as development platform and then don't provide JTAG access. The same company even sells ARM JTAG adapters :/ Yes, I'm aware of them, they all seem to be more or less the same.. but since we have seen leaked versions of the 6223 and 6225 SDK, we should start with them to have a 'known good' setup. I completely agree.

Hi Wenhui Liu, On Wed, Apr 14, 2010 at 11:54:21AM +0800, Wenhui Liu wrote: Well, the P1300 and P1302 are based on MT6225, a single-processor baseband design. The vendor provides a version of the MTK SDK exactly for the purpose of adding custom code to the baseband processor of those units. And JTAG is very useful for any kind of development. Even if you do not touch the GSM stack and only do application development, it is still useful for those developers to be able to trace through their code...

They should be assigned as indicated in the picture at http://en.qi-hardware.com/wiki/File:C3100_testpads_jtag.png The "RTCK" is a bit strange, it is the 'return jtag clock', i.e. you get back the clock that you send to TCK. I haven't tested any of those yet, but maybe at some point during the next weeks...
