Differences between MSM8255 and MSM8255T - Android Software/Hacking General [Developers Only]

Hi folks,
I am a owner of a SGS+ (i9001) which chipped with the chipset MSM8255T.
Now I've seen that are out some ICS-ROMs working with the Desire HD already which contains the (estimated) previous version MSM8255.
Unfortunately I could not find any useful information at Qualcomm, which shows the differences between these two chipsets.
May I use one of these ROMs as a base for my development for an MSM8255T or differ the chipsets too much?
There is an Alpha-Release from SE for the Arc S (4.0.1) which has the same Chipset as the i9001 ... but this lacks the basic functions including the modem and wifi ...
not a good starting point when i have the chance to start behind this limitations.
Nice holidays

Hi hirnwunde!
Funny nick )
I own a SGH-T679 (Exhibit II) witch is a half brother of the GT-I8150 (Galaxy Wonder).
What I can state that my phone works with SGW roms, issues are with the keys and the camera.
The SOC seem to be the same on different clock speed.
I don't know if there is a way to safely boot SE or HTC roms on Samsung phones.

You have to watch for other device though, for instance the screen and camera needs different drivers. that by itself prevents direct usage from other phones even though the cpu is the same..

What do you think of the Samsung Galaxy?

Hi, I don't want be rude and talking badly to the Samsung Galaxy but a new device with Android OS that has only a 3.2Camera and no- Flash seems bit absurd don't you think? The name has nothing to do with the real world...a galaxy or a star usually is very bright...with this phone you cannot even make photo or video in the night time...mmmm....not a galaxy whatsoever................
All I can say is: Stay with HTC models!
But the procesor and the chipset is a lot better then the crappy qualcomm. If only HTC start to use different processors.
Qualcom chip
Are you sure about that? I have an Htc Diamond 2, a Sony Xperia X1, and Htc Hero, they are perfect ! before that a Samsung D900...it was fine...nice phone but I could not do it the things I do with Htc or Sony.
u cannot compare phones with different OS, and I dont know what chip was used in D900. I am talking about Snapdragon(Qualcomm) vs. Hummingbird(Samsung).

have you seen the galaxy videos? it takes like 5+ secs to actually getting in to the gallery after pressing it. it seems kinda slow to me. unless that's because of the software being beta or something, that's slow to me.
@ qualcomm vs hummingbird: qualcomm will come out soom enough with dualcores.

1. seen that, especially the "Lady" that was clicking on icons like she was mad and launching few programs at the same time, but who knows.
and after qualcomm will come with dualcore, samsung will come with better dualcore.
I think there were some benchmarks comparisons, will try to find them.

Hello,
i was actually wondering if anybody knows how to Mod correctly a galaxy.
I have a galaxy from the middle east which does not come with marketplace. the I7500JVIL2. I have flashed it using ODIN to another rom I7500xiik, however many options stopped working like sdcard, camera, etc... i flashed it to 1.6, camera started working but sdcard still doesn't.
So, I was wondering if there is any way to get this fixed. I need sdcard so that I flash using recovery mod. I'm trying to flash it back to the original build I7500JVIL2, hoping this will make everything work again.
Do you think this is a good solution? Are there suggestions you can make on another build to use that has marketplace and everything working on the phone.
Sorry if I posted in the wrong place. I couldn't find anything regarding galaxy on XDA and I love this forum. I habe been able to succesfully mod my g1 through this forum.
Thanks,
VENI VIDI VICI

For me the only thing to like about the galaxy is it's name
I just realized that you are talking about the galaxy(i7500) and not about galaxy s(i9000).
BTW galaxys, you should sue samsung for using your nick.
Personally I wouldn't touch a Samsung with a bargepole, I have owned a few Samsung phones, where the phones tend to be okay they do not support them at all with firmware updates, they have a remarkable release rate of phones and rather than supporting the current ones they just release a new one!
Galaxy name
Yeah your right only the name is cool....I don't know why people don't pay attention to the market...We have around in Uk at list 10 top of the range mobiles, starting with HTC HD2, Htc Desire, Htc Legend, Nexus One, Diamond 2, Motorola Milestone, Nokia n900, Omnia2 and so on....Why buying the Galaxy?. I will give you another example: Which would you buy between Htc Desire and Sony Xperia X10???...Of course the Desire!!! they have the same price but Desire is on another planet: Android 2.1, Multitouch, better Keyboard, better interface...Maybe..the only thing Xperia X10 has better then Desire is the Camera that's all...Xperia X10 is basically a 2009 device sorry arrived to late!

Wanted: Galaxy Spica Developer! :D

Hello, im so happy at last samsung galaxy spica have a new home here in XDA
forum. Since i've using this phone i found that samsung galaxy spica only have a
very small number of developer. What a pitty, since this phone have a huge
hardware potential like multi touch capable chip, even some forum found that
spica has a 256mb RAM chip but somehow only about 160mb active.
So im looking forward for developer to help us spica user to unleash true spica power..

not only the hardware i guess, lots of pepole were using samsung spica as it is, since the other android phones were highly priced....so samsung galaxy spica is a well balanced phone between price and ability
What Theoo means by looking forward for a developer to unleash samsung spica true power is not just an empty hope (i guess...)
I recently bought samsung galaxy spica and my first impression is............I DONT NEED ANY SMARTPHONE AGAIN
Hope there will be someone who can deliver samsung spica to its full potential
Infact its a really capable phone.But samsung has written poor divers for it.The 3D experience is horrible.
There are many good developers like leshaK who r working really hard for its development but developing a phone is not a one man's show.
As said above,the phone is capable of multi touch support,it has a 800mhz processor which can be well overclocked like in case of moment,it has a second microphone which seems to be of no use.
If some good developers work on making drivers for this powerful phone,we can use the full hardware capabilities of this phone.

Yeah, like u said, its not one man show. Thats why i hope with our new home here @XDA, someone out there will be interested to develop driver or even roms for our spica. so in the future spica user will have many developer.

1. The Galaxy Spica has 256 MB RAM and 512 MB ROM. But only 146 was made visible to the OS.
2.It has a FM capable chip BCM4325, but was not implemented.
3.QT5480 chip is multitouch capable but was not implemented .(hopefully will work in android 2.x ROM)
U can look here for more information

Yes spica has the ability to update to 2.2.but samsung never update their old phone. I7500 for example. It's stop in 1.6.(official fw) .and samsung don't update spica. We have some good developers in samdroid. And leshak give us a 2.2.but not perfect . I hope xda developer can help us build a working 2.2. Our cpu s3c6410 support 3d but no drive. What a pity!

Thankfully tom3q working on a brand new 3D driver, but he might be happy for a little a help.
Since he is writing the driver for froyo, I think now our first step must be a stable & working froyo on the spica!
If some developer would like to help in that, the actual state of development can be seen here: forum.samdroid.net/f9/dev-android-2-2-froyo-samsung-i5700-alpha-2-gprs-3g-wifi-11-07-2010-a-1408
P.S.
I would like to say thank you to the XDA Developer team for making the Spica forum!
Adding myself to the bunch of people looking forward to spica development...
Didn't expect to see Spica around here. I'm glad it's here now though, might catch the attention of developers. I agree with some of the people who have mentioned the Spica being crippled by Samsung's poor implementation and support for this device.
I bought the phone in May, and love it for the things that it can do. I just feel that it's too early for Samsung to drop it and move on to their newer phones. This phone has a lot of potential.
Props to Leshak for working hard to improve the Spica. I hope more devs can pitch in.

[Q] Questions about kernel.

I post this here, as I can't post in development section.
Well, I downloaded the kernel sources for ChaCha in htcdev.com and I have some questions.
Why there is the source for drivers of hardware the ChaCha doesn't have?
Can the real hardware be guessed from the modules/drivers used in a kernel? Can we know that from the sources?
Can a different flavor of unix (maemo, tizen, webos, debian...) installed on ChaCha by compiling the right kernel? Will bootloader support that?
I come from a N900 where all this things were possible, up to the extents were open source drivers could be used. There is a site where up to the tiniest piece of hardware is identified with the N900.
If exists such a list of hardware of the ChaCha, maybe much better things could be done with the machine itself, even (maybe) 'port' things that other phones with the same or similar hardware does and ChaCha doesn't.
People that hacked the N900 (again) could get it to record videos up to 720p, wihch the N900 didn't support, and even run many games of the Palm Pre, that had almost the same hardware as N900.
Thanks all for reading this.

[Campaign] ICS-compatible OpenMAX IL compiled for ARMv6 from Qualcomm

Hello. I've just started a new campaign for Qualcomm. Please, support it by signing
http://www.groubal.com/ics-compatible-openmax-il-compiled-for-armv6-from-qualcomm/
As you might know there are millions of ARMv6-based devices in the world, and many developers are trying to prolong their life porting latest Android Ice Cream Sandwich to them.
Last time we asked you to release Adreno 2xx driver updates for ARMv6-based chipsets MSM7225 and MSM7227. And Qualcomm has released the update which is really greatly appriciated. (http://www.groubal.com/ics-drivers-compiled-for-armv6-from-qualcomm-update-drivers-released/)
But now we stuck at another point and we couldn't proceed any farther without the help of this great company.
I'm talking about OpenMAX Integration Layer update (core & codecs) for our devices. It is used for hardware-accelerated video recording and playback, image capturing, camera controls etc. Now we are able to use only software "acceleration" for that, which makes device almost useless for many things. It was present in Gingerbread, but it has lower API version, so we can't just use it in Ice Cream Sandwich.
Without help of Qualcomm it's nearly impossible to overcome, because our devices uses QDSP5 digital signal processor, which has no publicaly available specs to port OpenMAX by hand.
Qualcomm has also released updated version of the chipset named MSM7227a which has pretty same hardware (QDSP5 too), but ARMv7 core. Devices with MSM7227a are able to run ICS out of box!
These devices are affected by the problem (according to Wikipedia):
LG Optimus Me, Samsung Galaxy Fit, Samsung Galaxy Mini, Samsung Galaxy 551, LG Optimus Chic, ZTE Blade, HTC Legend, Mytouch 3G Slide, HTC Gratia, LG Optimus One P500 GSM, ViewSonic ViewPad 7, Samsung Galaxy Europa, Sony Ericsson Xperia X8 (SE Shakira), HTC Aria, Palm Pixi GSM, OlivePad VT-100, HTC Wildfire S, Alcatel OT-990, Micromax A70, LG Optimus chat L-04C, Huawei Pocket WiFi S II S41HW, Huawei Ideos X3, Huawei Sonic U8650, Sony Ericsson Xperia X10 Mini, Sony Ericsson Xperia X10 Mini Pro, Garmin & Asus M10, WellCom A88, Coolpad W706, Garmin & Asus A10, Samsung Galaxy Gio, Samsung Galaxy Ace, Odys Space, LG Optimus Net, LG Optimus Hub, ZTE Skate, HTC ChaCha, HTC Salsa, Huawei smart bar S42HW, Coolpad 7260, ZTE Blade S
Most of them already have a working port of ICS, CM9, AOSP, AOKP etc. Almost everything is working except multimedia hardware acceleration!
So, please Qualcomm, hear our voice again!
Please sign the petition if you have a device that meets one or more of the following:
1. uses ARMv6
2. has an unofficial ICS port (CM9, AOKP, MIUIv4, etc.)
3. does not have an ICS port due to the lack of these drivers
If you have anything you would like to say, please add a comment along with your signature.
Also, please spread the word about this Groubal (in forums, social networking sites, etc.). For example, if you are using some kind of ICS port, you can post in the thread of your rom. Or if there is a Facebook page for your phone, you can post there too.
Please do not sign the petition more than once or spam the petition. It ruins its credibility, not to mention that you are probably lowering the chance that our voice will be heard. If you really want to support this petition, then don’t spam.
Other than signing the petition below, please voice your opinion in the following links:
https://developer.qualcomm.com/forum/qdevnet-forums/multimedia-optimization-qdsp/13248
Use social networks to reach Qualcomm:

Custom firmware and snapdragon chipset

Hello everyone, I'm just asking for clarification about the custom rom: currently own a Galaxy S2 which as you well know is equipped with a chipset Exynox for which have not been released the source for the drivers.
Because of this failure to release, the rom that have been developed for this device, and of course the future, even if well designed, will never be 100% compatible with your hardware, or better, will never be optimized properly. Example: The camera, which with a custom rom takes good pictures, yes, but not up to those made with the original rom precisely because of the lack of support of the drivers.
The latest smartphone out, however, (practically all) mountain chipset "snapdragon", produced by qualcomm that from what I understand has released regularly releases and the various drivers for its components. This means that a rom (for example Omni or Cyanogen rom, I do not mean rom based on fimrware original), developed for smartphones that use this chipset, is considered almost "native" as compatibility? Photo and video for example, will have the same quality as those made ​​with the original rom?
In short, install a custom rom on a device with snapdragon chipset, it can be optimized to be considered as if the terminal was shipped from the factory with this rom installed?
There is something wrong in my reasoning? I do not understand something?
Thank you in advance
