Believe this should be question for all newbee as well.
Downloaded new source code from opensource.samsung.com
get all source and whole environment setup from android.com
follow readme in samsumg's source code so I'd merge with android generic source
After make, the output system.img is only 50mb. Compared with samsung's system.img 250mb. After extract, there are significant differences.
apps, bin, frameworks, csc.. are much different.
Anyone had idea how to build correct samsung's image?
I created new launcher and lockscreen, it works on emulator, but cannot port to samsung Galaxy S because of environment setup, your help step by step will be very helpful, thanks!!
Hi buddy,
Do you know what’s the problem?
I meet the same problem about compiling.
The system.img only 58M. I cann’t run the image with emulator.
I don’t know how to solve it.
I guess your problem is that you don't get the drivers on the sgs.
Many are not open source.
So you can't build a firmware from scratch.
The open source from Samsung is only the kernel.
What you need is to import all missing stuff in the firmware you did compile, but you will face a bigger problem to change all places that using the missing stuff.

Hi friends of XDA,
I think this might be helpfull for some of you trying to compile kernel from source for S5830i, for the first time.
If you are following the great tutorials to build your first kenrel like:
http://forum.xda-developers.com/showthread.php?t=1748297 from thewadegeek
The first thing taht will happen, is that you cant pull defconfig from /proc/config.gz for S5830i.
Why? There is no such file for your device in there.
Normally the next you will do, is go to the stock sources readme file. And will find out the defconfig is totoro_defconfig
You will compile the kernel with no errors, and you will feel very happy, until you flash your recently compiled kernel and see that you get stuck in the boot_logo screen.
Ok, dont panic, solution is very easy. Samsung readme file is a general readme.
Here is the quid of the question:
totoro_defconfig is not the correct defconfig for S5830i.
S5830i defconfig is bcm21553_cooperve_defconfig
You will find this defconfig in the sources, at:
common/arch/arm/configs folder
Hope this helped. If it helped dont doubt to press the thanks button, this will be very appreciated.
Thank you and sweet kernel development.
Samsung's readme file isn't general, they just took the Galaxy Y's readme (even the model says GT 5360).
What's stranger is that the CHN sources have the correct info.
Also, I didn't need to pull anything. I just used the default config:
Code:
export ARCH=arm
export CROSS_COMPILE=<path>
make bcm21553_cooperve_defconfig
make -j16
Hi GermainZ,
Thats right,never had a look at the CHN readme. I wonder why the other sources are uploaded looooollll strange Samsun guys.
Never the less, forgot to post the next in the original thread.
I recomend to have an original copy of bcm21553_cooperve_defconfig as when you start modifing it some options may fail and its recomended to have a fresh one to copy paste quicly.
Even more for my kernel i copy original file and rename it to nit_defconfig and give it a version number ej nit01_defconfig, its agood practice have latest working defconfig as you will be modifying the file a lot, btw nit is how i call my kernel as you all ready know, this comes from new innovative technologies the name of one of my companys i created recently
But good appreciation GermainZ is always my pleasure to talk with you

Thanks for your tips bro! You had a significant part in booting my kernel. Will add u in credits
No problem hell_lock.

General informations:
This thread's aim is only to represent a central meeting and discussion point for BCM21553 developers and, in particular, for the open Kernel/ROM sources development for the Samsung Galaxy Pocket GT-S5300 (codenamed Cori).
Information for common users:
As already described in the previous section, if you are not a developer, please restrict your posts to the general discussion thread so that developers can maintain good communication. Every post that is not strictly respecting these rules will be reported to the forum moderators. Thanks for your understanding.
For any other BCM21553 device related question or information, please, use this thread as a reference point, instead:
[DEVS ONLY][BCM21553 series] CyanogenMod 11 for BCM21553 Development Discussion
As someone already might know, I'm streambinder, from MoltenMotherBoard team.
I have already followed some projects for the GT-S5300, but especially kept in contact
with some of the events related to the porting of ROM and Kernel sources for BCM21553 chipset based devices.
In this precise moment, the sources in my possession allow you to be able to compile
a bugfree CWM 5.0.2.8 (based on CyanogenMod 7 code) with a kernel based on the Samsung stock one.
The only - fundamental - problem was due to the fact that unless I hadn't used the prebuilt INIT binary
token in the Samsung stock firmware boot.img, the phone would not work - or, better, boot up.
This means that until the situation - regarding this issue - doesn't change, our access to the porting of custom ROM
would be barred.
Recently, I decided to give Cori another chance and rework my sources, looking at the wonderful work brought
by the BroadcomCM team on CyanogenMod 9 (in particular, thanks to @bieltv.3 and @Alberto96) and @psyke83 on CyanogenMod 11.
They've not only been able to run these two ROMs in a more or less crude way, but this developer has been able to write
the necessary strings to make the INIT binary of some of these BCM21553 devices opensource.
Strong of this informations, I readjusted some of the sources of BroadcomCM's CyangenMod 9, which includes
all the progress carried out by both the team and psyke83, in order to make them work even on Cori,
and am now next to the first test of the CWM 6.X.X.X, based on IceCreamSandwich code.
At the same time, @akhbh is working on the KitKat code based CWM.
I hope I can give more information about any progress as soon as possible.
The General Discussion thread for non-development issues is here:
*.[DISCUSSION] CyanogenMod 11 For Galaxy Pocket GT-S5300 Discussion Thread
Made a first test of CWM based on CyanogenMod 9 code.
It seems it cannot flash it as it weighs so much compared to its partition configuration value: in fact, the maximum boot partition size is set up to 5.0MB, but the compiled boot.img weighs 5.3MB.
Will have to resize its weight in order to make it fill into the partition.
@akhbh, have you had any complication in these terms, with CyanogenMod 11 sources?
@psyke83, what do you suggest to do? Do you think an increasement of boot partition would be a better idea?

No, I didn't faced those complications. My boot.img weighted around 4.5 MB in lzma compression mode. In gzip, it increased to more than 5 mb.

Well, I took the GeTux kernel for cori, had to change the board name though and then compile it. CWM was booting even before changing the board name but there was no reaction from the phone on trying to boot cm9/cm11
And after changing board name, a black screen on trying to boot
Another info: When tried to merge cori source into the bcm21553 common one, it did compile but gave bootloop of GT-S5300 logo on trying to boot as well as when trying to go in CWM.
Bieltv.3 recommended to use cori source instead of the bcm21553 common one so we used cori sources

I suggest to use our Kernel sources for now, too: it will automatically bypass few errors/issues/bootloops that we cannot now fight with.
The most important thing is to make INIT working from sources (hope it will be working
on my CM9 sources, too) and check that every our configuration is correctly working and
making Cori boot into recovery.
Once we'll make it perfectly working without any kind of issue, will be the right time to try
to make Cori supported with the BC21553-common kernel.

Okay, I will use your kernel sources and try if something is changed once I reach home. For now, I neither have this device nor a PC, as I'm in another city.
Will be keenly watching your work. Will start after reaching home around the end of September

No problem, mate.
Here you have every source in my possession:
platform_kernel_samsung_cori
platform_device_samsung_cori
Keep in contact with me, as I will need some informations by you.
Anyway I'm now making another build, keeping some not so much important binaries excluded, so that I can make the compiled boot.img fill into our little Cori's boot partition. I know it's a dirty workaround, but if it works, I'll use it untill @psyke83 will suggest me a better way to do.

Of course, mate. I'm working on it, right now.
It doesn't seem to boot, strange if the same INIT binary sources are working for @akhbh.
#UPDATE
In order to troubleshoot, I'll give you some info.
For his build I used these sources:
platform_kernel_samsung_cori
platform_device_samsung_cori
android_device_samsung_bcm21553-common
Applied some lines on our bcm21553-bootimg.mk, too, in order to exclude parted and mke2fs and make the compiled boot.img weigh less.
@cleverior.ipul, can you link me your kernel sources, as akhbh said he used your ones for CM11.
@akhbh, which modifies have you applied in order to compile CWM based on CM11 code? Which device tree?
#UPDATE 2
Attached my compiled boot.img.
If anyone of you would extract it (you can easily use this tool: bootimgtools - read how to use it in the README) and make a diff with the CM11 one (just extract the ramdisk of both boot.imgs and - in the terminal - use this command: diff -urN /path/to/cm9/ramdisk /path/to/cm11/ramdisk > diff.patch), would make to me a huge favour.
Let me know.

I think we didn't had significant changes. Perhaps the same as totoro. But, that resulted in the internal_sd not mounting error in cwm.
Sadly, as said before, I am away from my home city and can't provide the files to you and can't do the boot.img diffs as well
Try to ask psyke83, he might have a solution for that

Then, if you didn't make any massive change upon the sources, then I'll only try using your kernel.

Currently, I can provide you the boot.img only. For the sources, @cleverior.ipul can provide the kernel sources coz as said earlier, his kernel is used. Well, we were working together to bring cm11 but weren't successful

here the link source https://github.com/cleverior/android_kernel_samsung_cori
i've changed the board name. If your device can not boot after using the zImage from this source, then rename init.bcm21553.rc to init.gt-s5300.rc.
@streambinder, what is grom? As bieltv.3 said that init built grom for cori is required to fix adb over cwm recovery. If adb gets working, then possibly the black screen while booting cm11 might get fixed

Sincerely don't what are you talking about.
Anyway, have to try to understand where's the problem with the not-booting CWM.
Will try with your sources and let you know.
there is no such kernel,device tree,vendor for my device.
I could build device tree via twrpbuilder tree generator,
but kernel cannot be found in opensource release center.
why am i need A605k? not F or FN or else?
that's because when i used A605FN recovery it has so many errors... and it makes me build twrp for A605K.
not for other models..
but.. i failed,
device tree built via twrpbuilder tree generator doesn't have omni.dependencies file
so, what do you guys think how can i fix those annoying things?
I know, this is not a question area, but i want to make Discussion with you guys to get a idea
Well if your trying to build a device tree and kernel source and vendor start with downloading android source in linux there are many great guides for this then download the sources for the A600F/FN or any other current model of the A600 then there will be a file in the folder for whichever source you downloaded that will allow you to pull resources from your phone like kernel recovery device vendor files ect.. use that and then import it to the same folder than try to build TWRP and test it to see if you get a working build if not then go back and try again their are many sources for learning how to compile twrp for devices that dont have it read those and try again.

I did find the kernel and source here: http://opensource.samsung.com/recep...menu_item=mobile&classification1=mobile_phone
(page 44 for SM-A605FN - A605FNXXU1ARD7)
I would like to build it myself, but my android development knowledge is limited (i do have a solid linux knowledge though).
Is this guide obsolete (https://forum.xda-developers.com/showthread.php?t=1943625)?
If yes, anyone knows where can i find an up-to-date one?
If not, any idea where BoardConfig.mk can be found?
Where can we find a guide on how to build a twrp? I would really like to learn how to do it
