[Q] Evaluation boards for Mediatek - General Questions and Answers

Hi,
We want to build a cheap mobile phone and think Mediatek and Spreadtrum seem to have the best complete SoC solutions, e.g. the MT6268. We're now trying to get hold of some evaluation boards for these. Anyone who can share any pointers on where to look?
We've reached out to the sales reps but haven't gotten any reply yet. Probably because we're a small startup.
Thanks

Where's the datasheet for the MSM7200?

I know i've seen a thread or two asking for this somewhere - Did anyone find it?

Nah that link doesnt work.
It provides a link, but you eventually end up with a page containing this message:
"Out of an abundance of caution, due to the December 31st, 2007 injunction ordered against certain Qualcomm products, Qualcomm has temporarily removed certain web content until it can be reviewed and modified if necessary to ensure compliance with the injunction. It may be several more days or weeks before these pages are accessible again. Thank you for your patience."
I was hoping someone downloaded it before it was taken off their website and will upload a backup of it somewhere.....
i think this is the one you're looking for.

Nope - Thats just some marketing material on the processor. The datasheet will be a few hundred pages at least (if not a few thousand) listing all the intricate details of the chip and how to actually use them.
Looking back over the cdmatech.com/umtschips.com sites, that is now down, through web.archive.com at the last point it was up back in 07:

MSM7200 Chipset
http://web.archive.org/web/20060615182655/cdmatech.com/products/msm7200_chipset_solution.jsp
I dont see the actual datasheet we are after although all the other marketing stuff and chip diagrams are still there for dl...
The MSM 7200 datasheet has never been publicly available, the best you can do is look at the android MSM kernel and work it out from that. (though that is MSM7200A and some things are different, mainly the vic and usb).
The datasheet *WAS* available, but Qualcomm took it down after their legal woes with Broadcomm. Unfortunately, nobody saved the PDFs for the 7500 and other data sheets found on the Kaiser wiki.
The good news is, someone did save the PDF for the 7200 data sheet and it has been updated on the wiki. Go there for a working link.

Apparently, I haven't read this post until now The datasheet on the wiki is just marketing material. Not the 100+ page PDF you're looking for. Sorry, keep searching!

No problem I just wish I could get hold of it somewhere... i'm curious to look at the registers for overclocking and then also on how to wrap the standard gdi driver to use the integrated graphics of the processor..... i'm putting also trying to source more info on the official wm6.1 rom that's comming from htc - the local guys here say there's one comming but they dont know precisely when it will be available.

Not sure if this is the datasheet but will post maybe its it.

It has aleady been established that the datasheet should be more than 4 pages, probably more like hundreds of pages. This looks like some kind of marketing document with chip specs and a diagram.
I'm wondering how some of those peoples who try to build a graphics driver for the Polaris can do that without any hardware reference? Why has no one access to such papers?
And what is it with the android kernel dzo mentioned? Where can I
get such a development enviroment to test my Polaris with Android?

It would not be possible to develop graphics drivers without the technical datasheet.
The Android kernel is being developed by Google and they certainly would have the datasheet for the processor.
Whether or not they are developing the kernel with hardware graphics accelleration in consideration I am not sure - It would be marginally possible to eventually disassemble such a kernel to determine how the graphics hardware is addressed, but that would be a vast and intricate task with many many hours of work without any guarantee of success.
I dont think you'll find anyone willing to look at gdi development without the actual technical datasheet.
Is this zip file the 7200 datasheet? I've tried to unzip it but get an error. Any help you could give would be appreciated.
Would it be possible to find the data sheet for atleast the graphics on AMD's site, the chip from what I understand was made by ATI before AMD bought them out and sold the mobile graphics section of ATI to Qualcomm. So, they "may" still at least have that data sheet available. Well if anyone actually knows which Imageon it is anyway.
What you are looking for is actually a reference manual, or programmers manual (or better yet both), for the msm7200 and not it's data sheet, which in most cases is actually the marketing "blabla" (that varies between companies though).
Unfortunately quallcomm took over broadcom's buissness strategy and gives the documents only to those that have paid for them in terms of licencse's and hardware
regards
There are proper reference manuals on the internet, though I have to point out that this information appears to be regarded by Qualcomm as proprietary.
As of the date of posting this material is still available, however:-
Google for
80-VA736-2-MSM7200-SoftwareInterface.pdf
and
80-VE263-25-MSM7200A-BasebandTopics.pdf
and take the ftp link which should come up early in the search results.
These appear to provide a full reference; the first is 910 pages and the second is 79 pages. They include very detailed register and pinout information.
Please note that I did not personally place this information on the net and reiterate that it is clearly marked confidential and proprietary. However it is clearly extremely useful for any open source development.

Jtag HTC Recover Unbrick Device?

I do all types of repairs at my location and i wanted to start doing unbricking for xda members. I currently have the XTC clip and have rooted several phones from members and i want to continue helping the members out on this forum as i have learned alot and made my personal phone much better.
Which is the best device that has the most compatibility with phones?
Where would i get the jtag points for each device that i will be working on?
For example if i unbrick a HTC Aria the points for the LG Dare will obviously be different is there information so that i can find those points?
I am new to phone repair but have been doing electronic and BGA repair for quite some time. Thanks for helping me help you.
I looked at the Riff Box, which has decent compatibility with several devices. But if theres something better, i will invest in it.

What is wrong with MediaTek SOCs

I can't seem to find out any proper information or benchmarks for the MediaTek SOC's that are being used on budget smartphones these days. I have read many user comments which didn't inspire any confidence about these SOCs. Are they really that terrible for performance or are those comments out of prejudice about the mediatek cpu's being using in chinese phones?

Actually, its due to the lack of info about them which is resulting in this. They dont provide much info to the end user/devs. I had a phone based on a mediatek chip about a few years back, and had trouble figuring out much about it. It was a fake nokia model. Eventually, just threw it away.
from what i know and can see on you tube there's actually a lot of information about MTK soc based smartphones.
you just have to know what model to look for. i suggest u check out merimobiles and see what it is ur looking for and then checking google for it.

[Q] Off Subject but interesting....

I have used these forums to find all kinds of answers for my phones or tablets, but today I have something completely different. I already know that it isn't a tablet that "doesn't belong" or it isn't popular enough to hack, but I am only looking for people who can help me out. I have a LeapPad 1 Tablet and I wanted to know if this group of the best hackers around wants to take a stab at it. I am looking to run a flavor of linux on it and I know that there are other devices that use the SoC it has in it. So anyone up to the challenge.

[PARTNERSHIP] Doogee and XDA

Hi, I would first like to share that I'm a moderator on Doogee forums and am also a Doogee owner. I have a direct contact with the admin on Doogee which he has access directly to all Doogee department.
I have talked about the software issues arising and the development of it with the admin and feedback from members there, and it seems that we need help in improving the software side. The admin has approved my plan and I am speaking here in behalf of Doogee.
All we ask is help from experienced developers and programmers here to develop and help improve the software of all supported Doogee models. We need to know what we need to provide and what you will need in order for this to be possible. Please bear with me here, this is a big chance for XDA to be known better.
Doogee, for your information, has a very high potential to compete with popular brands like Vivo, Oppo, and even Samsung. Can you find a phone worth $300-$400 that has an insanely 8GB RAM of hardware? No. Their phones are powerful and yet the price is reasonable since the parts they use are direct and in return they can make it at a goid price unlike overpriced brands.
Please help us out here, just let us know with what resources are needed to make it possible. I will make sure that XDA will have its name on to the partnership with Doogee.
Thank you for your time!

We're calling out skilled and experienced devs out there
Let me clarify that we will be working on the official ROMs, not custom ones
Custom ones can be added later on.
Bump!
Please let me clarify that we are not only the one who will benefit here, but XDA as well. We will make sure to have your names as a credit and the XDA forum as well.
If someone here is interested, please leave a reply here. We just need to know what we will need to provide and help needed so we can get started on developing the software. There's quite a couple of things needed to improve Doogee's software here, thanks for your consideration.
One of the biggest things is kernel source code. Without it you will be hard pressed to improve anything. Next would be access to the code for the OS.
I can't say I have ever heard of the device as they are not sold in my country.
Their rugged devices are probably what they are best known for; they have devices sold / targeted in/at the US via mail order. It seems someone from alaska would probably be interested in them. The s80 and s90 models include a UHF radio / 'walkie talkie' feature.

They survive up here as much as any other. The walkie talkie feature is useless really. The distance between people is too great for this most of the time. Also it doesnt help that most OEM hardware (this one too) has a built in kill switch when the device hardware drops to 32 degrees or less. This will shut a phone down. Also in lot of places where you need a rugged phone, you really dont even get gps let alone a cell phone signal. Like one of my jobs puts me out in no cell phone or gps signal range for weeks on end. No phone (even a sat phone) does me any good out there. So we have gotten to the point of not even carrying one when we go out to places like that. Other then that. The only real things needed are an IPS rating. Anything else is just icing on the cake.
I'm glad to see xda and doogee working together.
As the title states I am glad to see xda and doogee working together it gives me some piece of mind as far as future support and updates go. From some of the posts read some people are not familiar with doogee simply explained they are a Chinese cell phone maker that make Android phones and recently are more well known for there line of rugged phones. First let me state that this is my first rugged grade phone I've owned also it's been my second phone from China if you count the tmobile revl plus/ yulong phone. For years I've looked at different rugged phones with with little to no interest they usually were overpriced and underpowered until I found out about the doogee line of rugged phones. After looking at there line of phones and the competition I decided to go with the doogee s70 lite for the cost performance and making a educated guess that it might possibly sell more then other rugged models. I also went with doogee because I like the idea of modular phones like the s90 have yet to see a company have much success with the concept I owned a moto z2 and the only add on I considered buying was the battery add on. Back to my point. I'm glad to see xda and doogee working together since day one of buying my s70 lite I've worried about support and updates and figured I'd eventually have to go the custom rom route or look towards third party updates. Anyway so far with my s70 lite I have not noticed any major bugs to mention or bring up so far I am quite pleased with how Stable things run. I am really impressed with the hello p23 chipset on how well it runs apps and how little power it consumes and how cool it runs on temperature I've ran qualcom soc phones for years and the few mtk chips I have ran seemed a bit laggy and unstable i must say mediatek really upped there game with the hello chipsets and would recomend one for multiple reasons. My only gripe with the s70 lite is how long it's been since it's had a security update release but overall i would recommend a doogee rugged s series phone to anyone that is tough on there phones at work. Only other thing that is a minor inconvienence is the recovery is in Chinese conji which I can't read a English translated recovery would be nice or a third party twrp/clockworkmod port for the s70 lite or the s series in general would be nice I have considered trying to do a port of twrp recovery for my s70 lite but due to being busy at work and little experience dealing with mtk chipsets I have not attempted it yet. Love my s70 I really hope doogee sticks around for a while. Would recommend there s series phones to anyone working in a industrial/blue collar field of work I work as a automotive technician and average breaking my phone every 2 months. Has been a month now with my s70 lite not a scratch on the screen and I've done some durability tests. Who wouldn't want a phone you can shower with lol. I've even considered trying to promote and spread the word about there s series phones so if doogee wants to send me some phone pamphlets I'd be more then happy to hand them out to my coworkers and others that work in my field. Also anyone reading this if you buy one try to order it direct from doogee I did not have the option when I bought mine I ordered mine off dx.com and I recommend getting the express shipping.
Without the kernel source code: no.
However, provide us with API documentation for the optional attachments, firmware source code, local OTA server config, kernel source code, the original build compile folder, and anything else that could be used to develop the phone, (repair manuals, etc) FOR FREE... then maybe we'll be more open to developing the phone for you.
Sorry if this is a bit harsh sounding, you guys make great phones

Hi my name is Jose, I was owner of DOOGEE MIX i ask too much time for kernel source and u didn't provide to me. Without kernel source we can't do nothing, for example a good custom kernel overclocked a custom rom. I think a good idea will be update the phone to a newer version. But pls give to devs like me kernel source and we will can help u to get a good stock rom.

Hi, thanks for your interest. Unfortunately, I myself can't even get my hands on it, I have talked to the software department yet they are not handing it out, they believe it is for security reasons.
Is the S90 getting a Pie update?

If you make that DOOGEE release their kernel sources, the developers i think that will work on mediatek devices and they will help on stock and making customs roms.
So please, try to make DOOGEE release the kernel sources.

Yeah this is stupid as hell. I still remember doogee phones ard 1-2 year back were preinstalled with malware(this can be found online). I suspect they might as well have put some weird **** inside the kernel source so they don't want to release the source code.
The thing is that they don't make kernel source and software by themselves, it is made by HCT, so they just do the hardware. So if they pay to HCT, they will can release kernel source, since HCT will gave it to them.
Thanks
Regards
Jose
I know this is an old thread, does anyone know if the kernel source is custom by HTC, and should we be contacting HTC to release the kernel source code?
I have a DooGee S95 Pro and it's a decent phone between the S95 Pro and the Samsung Galaxy Note 20 Ultra 5G is a great phone. Whichever phone gets LOS first I will use. The S95 Pro has been out a lot longer and isn't a bad phone considering the newer ones from DooGee are not as nice. Anyhow either that or I will switch over and buy a Samsung Galaxy Note 20 Ultra 5G if LOS gets there. Both fronts are interesting. If I can get the GSI working without issues on the S95 Pro I will just use the S95 Pro but otherwise if not, I will have to sell it and switch brands.
I mean what's with DooGee and other manufacturers other than Samsung and Apple making a good phone and then the new models come out without some of the features I like. The new DooGee phone just has most of what the S95 Pro has, removed take the S97 Pro for example it's maybe a better phone, but the screen is still LCD not AMOLED and not 120Hz or anything. It's a rugged phone and I like that but I can't really use it because it's on Android 9 and not updated at all also no LOS on it which totally sucks. Why give a phone to a dev and have the dev port over LOS for the phones it would probably cost less than having HTC supply source anyway.
My two cents worth here. I don't have any android devs on staff that can do this kind of work anyway which sucks otherwise I would have it done.
Thanks
