[DEV] Kernel Compiling

Hi all! I'm not a dev but i really want to do something for this phone so i'm trying to build a custom kernel.... if anyone have tried the same report here the issue, i will do the same!

I have the pre-requisites for compiling a kernel set up. However I am more interested in getting ClockworkMod Recovery working on our phone as that will encourage developers and we can then start looking at getting CyanogenMod 7. I made a topic here asking for help but I haven't received any replies yet.

I have just compiled a kernel but it doesn't work.... this because - i think - i used the initramfs provided by leshak for the i9000.... now i'm trying to extract from phone......

Kernel
Hi Skin1980, I also compiled a (stock) Kernel two weeks ago - problem is, Samsung does not use the "normal" way of storing it in a boot.img file. That is why I wasn't able to push it to the phone or at least fastboot it. I would be glad to hear from you how exactly this is possible, if you find out.

I used the redbend_ua you can find here to write zImage to bml7.... how do you do with initramfs that is missed when you build the kernel?

Have you managed to extract initramfs with redbend_ua?
If you don't mind, please take a look at this post. There is a step build/tools/device/mkvendor.sh device_manufacturer_name device_name /your/path/to/the/boot.img. Because Samsung doesn't use this boot.img building a recovery looks tricky. Any suggestions would help.

and if we can find the initramfs i think that is not difficult to modify the recovery to allow unsigned zip files installation

Perhaps, we could use parts of the following method:
h**p://android-dls.com/wiki/index.php?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images
To extract the ramdisk from the boot.img, they do the following:
Then, look for a bunch of zeroes followed by the hex 1F 8B (which is the magic number of a gzip file). Copy everything from the first line of the file, through the zeroes, and stopping at the 1F 8B. That is the kernel. Everything from the 1F 8B through the end is the ramdisk. You could save each of these files separately. In order to see the contents of the ramdisk, you need to un-gzip it and then un-cpio it.

I know that we don't have a boot.img, but we do have an image including kernel and ramdisk - this should be very similar. And if you can locate the named headers in the file, the extraction should work. Further info and some useful commands can be found behind the link.
Sadly, I won't have time to try this before next weekend...

Which file are you referring to? I have some time, I can give it a shot.
EDIT: I found "initramfs.c" and its object file "initramfs.o" under GT-I9003_Kernel/kernel/Kernel/init from the Samsung opensource tarball. Don't think that helps us though.

@rb210: I mean the dumped bml7 partition. It's an image of a partition with a kernel and ramdisk in it, or did I misunderstand something?
PS: You could try "SGS kernel flasher" from the market. It's got a backup option - look if it does produce the same image of the bml7 partition (I tried it, it did a backup image of around 8MB on my SGSL, which is about the size of bml7, as far as I remember). It would be faster and easier to carry out than using a script.

Ah I see what you mean. I was trying to figure out how to extract the initramfs from the opensource package from the Samsung website. I figure if they're providing the kernel and platform, there's got to be an initramfs somewhere. You'll are talking about trying to extract it from inside the phone itself.
I'm still not sure how this is going to fit in with porting Clockworkmod as per that method in the blog post because it's still an initramfs and not a boot.img. Getting custom recovery is vital to attracting development for this phone, we should not make the mistake of overlooking this.

Ok so as they say "safety first"
Let me give you your CRASH HELMET
It is said that x10 is UNBRICKABLE, though that is true but not hard and fast rule. Jerpelea and Doomlord have bricked x10 devices before and it's not all that impossible. Still, if you keep care of following things, you'll never brick your phone
1. NEVER DISCONNECT USB CABLE while flashing/bootloader unlocking/pccompanion upgrade is going on
2. Be extremely careful while using the_laser or 9Lukas5's unlock procedure. It changes device partition and mapper modules so they are delicate ares and can brick your device if procedure is not followed
3. DO NOT PANIC, THINGS CAN BE SET RIGHT. BE CALM, BE PATIENT, ASK FOR HELP AT XDA
=======================================================================================================================
Ok so, there can be bad flashes or whatever..... what to do if device does not boot up??
1. If the problem is about RED flashing led, then just plug your phone into a charger and wait over night it's a low charge problem. Once charged, all will be ok
2. If you face boot loop and you just do not know what to do (i.e. you cannot go to recovery too) then do this
a.) either download PC companion and update/upgrade your phone
OR
b.) download latest flashtool and flash a 2.1 for 2.3.3 firmware (that you get in .ftf format) that will set you on track

ok so to tell a few things first....
please do not pm me.regarding this.
ask any questions here.
i or any other member would definitely help
and dont get impatient.... I'm busy...so it'll take time to complete the guide

decompile settings.apk and go through the xml files you get and play around with them a little....

this one

Ok, so lets get to our stuff fast
Her we begin with some info about how a ROM works
when cooking/porting roms, you are concerned with only a few folders
download any randon ROM zip and unzip it and see what it contains
1. /system/app -> this folder contains all apk files of apps
2. /system/framework -> this folder contains lots of .jar files that defines how the base operating system will run and function
3. /system/lib -> lots of .so files that are like drivers (yep .dll files in windows), these specify how the software communicates with various hardware components
4. /system/etc -> very dangerous folder contains lots of important configurations
5. /system/etc/permissions -> these contain lots of xml files that are required to define how the .jar files in framwork folder will work
ok so i'll elaborate point 2 and 5 a little more taking example of the panorama beta app by SE. it requires the com.sonyericsson.android.seee.jar file in framework folder to work but if you just keep the jar file, it'll not work. you need to sort out its permissions too and for that you need to put com.sonyericsson.android.seee.xml file in permissions folder
Click to expand...
Click to collapse
also the etc folder contains two some files called
gps.conf (which defines which gps server the device will use)
hosts (this defines which websites will be blocked .... yes that is your adblocker file )
apns.xml (which defines your apn configuration)
screwing up these files can cause you internet/gps/data traffic problems. also intelligent editing of these fils can give you better gps/data too

hey champ!
First I'd like to thank you very much for this nice guide and for your kernel. With latter u saved my ass. Was on Doom's with FeraLab and phone reboots sometimes Now it's flying!!!
But I'm fan of good design. And please don't hit me, but I'd like to change the boot-logo of your kernel is there any way? Or do u have any nice guide to change logo?
Would be awesome!!!

Question
Hi champ,
Does THIS also work for X10?

I've one question left I think
I'm currently on Windows 7 ultimate, and I have 1 TB left on drive D (which is empty) My question is.. Is there a way to Dual-boot Windows & ubuntu without wubi?
Thank u very much again

Compiling kernel
So letme tell you how a kernel for x10 can be compiled
1. install ubuntu (through wubi or in vmware will also do) but i prefer on a separate partition.
2. Install the following packages
git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
here's how you go about doing it
Code:
sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
sun-java6-sdk is no more officially available through ubuntu repositories
so you will need a workaround.... so here are some helpful articles
http://www.gaggl.com/2011/10/installing-java6-jdk-on-ubuntu-11-10/
http://superuser.com/questions/353983/how-do-i-install-the-sun-java-sdk-in-ubuntu-11-10-oneric
http://softwareinabottle.wordpress.com/2011/11/17/install-sun-jdk-6-on-ubuntu-11-10/
In case you are on a 64-bit version of ubuntu, (btw i strongly recommend using a 32 bit version for android development as you'll face various problems with 64-bit at various stages) you'll need these packages too
ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib​
3. Next you'll need a cross-compiler.
a cross compiler is used to compile for a different architecture than from the one you are currently working on. in this case you are either on a i686 or amd64 pc while the kernel you are compiling is for an ARMv7 processor.
for ubuntu, getting the Linaro GCC cross compiler for arm is getting as easy as
Code:
sudo apt-get install gcc-arm-linux-gnueabi
4. Now you are pretty much set up to compile kernels. Next we need sources.
So let me link you up to the most common available ones
Sony Ericcsoon Official Kernel Sources for 3.0.1.G.0.75 (gingerbread firmware)
Sony Ericsson Official Kernel Sources for Eclair Firmware
FreeXperia Kernel For ICS
FreeXperia Kernel for GingerBread
DoomKernel (this is my forked repo)
*** i'll update this list later (there are dozens of kernels for x10, all have their sources, i guess for now, this is enough)
5. So the source you have downloaded will be either a tar or zip archive. Using archiver, extract it into a directory of your liking.
6. Open terminal and 'cd' into the kernel directory. The kernel directory is the one which contains the folders arch, block, crypto, firmware, drivers .....
for compiling kernel you need to be in the root of this direcrory.
7. So here are a few codes that will get your kernel compiled
To clean source directory : -
Code:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make clean
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make distclean
To get default configuration
Code:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make semc_es209ra_defconfig
if you are compiling FXP kernel then instead of semc_es209ra_defconfig you need to write fxp_es209ra_defconfig , and likewise for DoomKernel you need to use doom_x10_defconfig
To configure the kernel
Code:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make menuconfig
inside general setup you can name your kernel
and inside power management setup you can setup which CPU governors will be present and which will be default
do not mess to much with the driver setups or with "kernel hacking" area....
do not touch things that you have no idea about
Finally... to compile the kernel
Code:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make
If all goes well, you'll get this message
Kernel: arch/arm/boot/Image is ready
Kernel: arch/arm/boot/zImage is ready
If you get stuck in between, nothing to fret about. Just post here what problem you faced, amd me or some other helpful soul will help you out
8. I know you are thinking "whew!! are we done??"... ha ha ha!! no buddy!! not yet... much more work to do.
Firstly from you kernel directory go to arch/arm/boot (using a file explorer, not a terminal) and inside you'll find a 2~3 MB sized file called zImage. Copy that file into a separate folder where you'll stach all your finished works.
9. Now we need to compile the wifi modules.
It is imperative to note here that wifi modules should be compiled immediately after kernel has been compiled. DO NOT run "make clean" or "make distclean" commands in the kernel folder before wifi modules have been compiled
Click to expand...
Click to collapse
For compiling wifi, you'll need the "vendor" folder (which is there in official sony kernel sources but not present in Doom's or FXP's repo). So if you need just the vendor folder, you'll HAVE TO download the official kernel sources too.
in terminal 'cd' to vendor/atheros/wlan/host/ folder
edit the localmake.linux.inc file using a text editor
Code:
sudo gedit localmake.linux.inc
edit the line ATH_CROSS_COMPILE_TYPE := arm-eabi- to ATH_CROSS_COMPILE_TYPE := arm-linux-gnueabi-
also in the line
# ATH_LINUXPATH := < kernel source path >
remove the # (uncomment it) and insert the appropriate kernel source path (the folder that contains arch, crypto, firmware, drivers etc folders.
now to compile wifi modules, run this code
Code:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- KERNEL_DIR=/path/to/kernel make
of course, in place of "/path/to/kernel" type the actual path to kernel on your pc
this will get your wifi module compiled
go to the folder
vendor/atheros/wlan/host/.output/QUALCOMM_ARM_NATIVEMMC_BSP_REV=3240-SDIO/image/
and you'll find a file ar6000.ko
transfer that file to the place where you kept your zImage safely earlier.
10. PHew!! done?? ha ha .. no dude.. still not...more work left
now to pack things up, you'll need a ramdisk.
so lets steal a ramdisk from a already working kernel (for stock kernel take stock ramdisk, for cm7/cm9 take respective ramdisk)
take any kernel and unpack it using instructions given here
the file ending with xyz.cpio.gz is the ramdisk. rename the file into "ramdisk" (without any extension) and put this file into the folder where you kept your zImage and wifi module.
Now transfer all these three files into a folder which is accessible from your Windows partition (oops... yeah... without windows you cannot finish this job)
Rest of the steps that follow are to be done on Windows (i have not tried on WINE)
rename zImage to "image"
now using this tool (courtesy DoomLord) pack your ramdisk and image into a flashable .ftf file
also make a copy of the file ar6000.ko and name it wifi.ko
both these ar6000.ko and wifi.ko files are supposed to be in the folder /system/lib/module of your mobile (please create appropriate flashable zip for the same)

When I attempt to compile kernel from source, Sony said in the read me file that memory layout and other stuff are passed to kernel via cmdline. I do that just like it's written in the cmdline I quoted?! because I want to use the latest kernel source with an existing zRam but i'm unable to make the newly compiled kernel to boot because I am unable to pass arguments via cmdline on boot :crying:

I'm sorry I wasn't clear in the previous comment, here is what Sony mentioned:
In the official SW the following command line arguments are given

unmkbootimg as of version 1.2 now supports embedded boot images, e.g. a boot image embedded deep in an update.img file.

Can not extract zImage?
Could you check why I Can not extract zImage from this Kernel:

It's because it's not an Android boot image, but a Rockchip specific kernel image file.

Hi, could you please post the source here or upload in github or similar and provide the link. That will be much better.

Why? It's a trivial hack, and if you're a programmer, you'll put one together in minutes anyway.
So, no.

That is very bad and unethical. It is not a question of I or somebody can do it. Even it violates many things by saying no. What a pathetic situation.

You, my friend, are making a fool of your self. Please, don't let me hinder you.

I am trying to spread the awareness against the closed source behaviour and I hope I achieved that in whatever miniscule way.
I don't care about your binary or code but thought of asking you to know if you are intentionally not giving the source by giving just the 32bit binaries. Anyway so now everyone knows...

[DISCUSSION][DEV] TWRP for X8

Okay guys. So over the past few days I've tried to compile KXP (AOKP for X8, if you didn't know) and failed.....thrice. The main aim behind this was to get
a) AOKP m6 for X8
b) TWRP running on our device
Now a) is still resulting in failures but b)....well, let's just say it can still be worked on. So this is what I've done so far:
I compiled a CWM version (without compiling KXP) just to get the environment ready for building TWRP. Next I edited the BoardConfig.mk to include these lines under a heading of #twrp like this
#twrp
DEVICE_RESOLUTION := 320x480 (the device resolution)
RECOVERY_GRAPHICS_USE_LINELENGTH := true (this line is supposed to improve graphics on some devices)
TW_NO_BATT_PERCENT := true (this line prevents battery percentage display in the recovery GUI)
TW_NO_REBOOT_BOOTLOADER := true (self-explanatory; we can't reboot into bootloader, can we?)
TW_NO_REBOOT_RECOVERY := true (this option never worked for me and so I removed it)
I sent the binary (obtained by typing make -j# recovery after copying the TWRP repo to the bootable/recovery directory) to feherneoh (the dualboot dude) and asked him to use it in a kernel, changing nothing else but the recovery binary. He said the phone didn't even boot.
Now I've noticed there are a couple of other libs and files built with TWRP. And also there's another recovery binary in /out/target/product/shakira/symbol/system/bin.
What I'm trying to do is compile a kernel with this binary. So far feherneoh's failed. And I'm pretty sure there's something else that needs to be done. I know about the recovery GUI images; I will place them in the res folder and try again but I'm pretty sure it will fail.
So i'm asking experienced X8-ians to help me out, especially devs like Daveee10, Rohin, nAa, alfsamsung, djnilse....the list doesn't end.
Looking forward to replies.

This is what lead dev of TWRP, Dees_Troy had to say:
Re: Compiling TWRP for X8

RECOVERY_GRAPHICS_USE_LINELENGTH := true
TW_NO_BATT_PERCENT := true
TW_NO_REBOOT_BOOTLOADER := true
TW_NO_REBOOT_RECOVERY := true
I haven't tested it myself. However I sent a fellow member (with experience in this field) the binary (from /out/target/product/shakira/system/bin) and asked him to integrate it with a working kernel, changing nothing else but the recovery binary. He said the phone didn't boot up. I believe the images from the /bootable/recovery/gui/devices/320x480/res/images have to be placed in the kernel too, in order to get it working. I am very new to this and would greatly appreciate if you helped me with the following:
What files are related to the TWRP recovery?
What has to be done to integrate it with a kernel?
What files need to be edited?
Do the libs built along with TWRP need to be installed on the phone?
Thanking you and the rest of Team WIN in advance

Generally speaking, the actual recovery files would be in out/target/product/shakira/recovery/root. What you have to have for integrating into your kernel build will depend a little bit on how your kernel ramdisk(s) are packed. You'll need, at the very least, the etc (for the recovery.fstab), sbin (binaries and libs), and the res (theme and zip signature keys) folders. Recovery usually gets its own init.rc so you'll have to do whatever you need to do to get the recovery/root/init.rc integrated into your kernel or at the very least, modify an exising init.rc so that recovery gets the LD_LIBRARY_PATH value as covered in the guide.

Here's the link to a zip I uploaded: http://www.mediafire.com/?ad374fp01274e3z
It contains the output files when TWRP is compiled as a binary (in the "TWRP(binary files)" folder) and the ramdisk-recovery.cpio when TWRP is compiled as an image by issuing make -j# recoveryimag (in the "TWRP(image files)" folder).
Note: The binary didn't build the res images. They had to be taken from the gui folder of the bootable/recovery directory. However the images were there when TWRP was compiled as an image in the ramdisk-recovery.cpio.
Note 2: This is compiled using jb-wip branch. The first binary and image was compiled using master branch. I later found out that I was supposed to use the jb-wip branch instead of the master branch.

Well you should make it to compile with rom together. When its built then u will get "ramdisk-recovery.img" or zip... inside this one you will have all needed binaries and images. Then just open kernel ramdisk and replace those binaries. There are lot more needed binaries than just "recovery".
But first you must compile everything

You mean like make -j# recoveryimage.

Problem with brunch is I run into some errors while compiling the ROM (which stop the building) so I won't get any end product. I tried recoveryimage and got a lot of ramdisk-***.img's and cpio's and what-nots.

The brunch not help Tried a lot of variant (compile only the recovery/compile with rom/millions of different settings/etc...) The phone start the recovery, but not work (the best result is only a flickering image). Earlier I consulted with Daveee10, but he have same results.

I couldn't extract ramdisk-recovery.img but I extracted ramdisk-recovery.cpio and I get a lot of files in the sbin directory like recovery, sdparted, fix_permissions.sh, adbd and a lot of libs. In the etc directory there is a recovery.fstab.

Yes. I examined a disassembled recovery binary from other phone (what is working correctly), the recovery depends on these binaries:
libz.so, libc.so, libstlport.so, liblog.so, libcutils.so, libstdc++.so and linker. These binaries needed in the ramdisk.

But should these be in the sbin?

Yes, you can place here. Or any other place, but need to add the path in init.rc. For example:
export PATH /sbin
EDIT: I forgot, libm.so also needed

One more thing. Should I try this with ICS or JB?

I tried with cm7 For my own goal the ICS/JB is too slow/unstable. But Daveee10 working on twrp with his own JB project, looks like he have same results with CM11 than me with CM7. I think the problem source is not the CM version, maybe something missing from the device specific files.

Like the guy above me asked. How does the camera react on this one? Same functionality? Or loss of important parts like bionz etc..

Very Nice

Read somewhere that modem and camera are disabled.
So we can't know how the camera react at this moment.

Thank you very much! Will such devices as amami, togari etc. be added too?

Attention: "For example, the camera is not working and the modem is not enabled, which means you cannot make phone calls."
Von meinem Sony Xperia Z1 gesendet. Mit Hirn.

Please @jerpelea can you put up a tut for building this! :crying:
I have downloded the source, and setup the build environment like you said on github but having issues with the final out directory.
It builds 100%, no issues whatsover, but mkbootimg fails to build the boot.img and it doesnt build the system.img :crying: I only have the userdata.img, kernel, and a system folder (others as well but these three are the important ones, oh theres also the ramdisk.img as well)
I have tried compiling the system folder using mkfs.yaffs2 to a system.img file and that flashes fine, userdata.img flashes too but the kernel I have tried a few combos and I can flash the boot.img file using files I have compiled before but it never boots. Its hard to see whats going on because I think the system folder never flashes properly so I dont have access to adb or anything. Its hard to trouble shoot this as well because it "bricks" my device everytime and its time consuming getting it up and running again. The build.prop looks fine and all folders in system folder look spot on but I am clearly missing something. I tried the fastboot flashall as well but that didtnt do anything, it gives me an error saying something about it must be an OUT_DIRECTORY... or something (yes I have tried it from the out/target/product/honami/ directory but same error, I think its because its looking for a system.img file..)
Please can you give me a kick in the right direction? I have been pulling my hair out trying to flash this but its a no go.
Desperately want to get it up and running (I am prepared to even go a few days without the radio just to test it and I can live without the camera as well)
PS: Sorry for being such a noob!

Hey bro
Nope. I put mkqcdtbootimg in my /bin folder so I could execute it from anywhere but it still wouldnt work (by the way, you have to compile mkqcdtbootimg using "make mkqcdtbootimg", wish someone told me that before ). So I compiled the kernel seperately and got a boot.img, put that in /out folder and tried fastboot flashall, nope no go. Useless.
I cannot make a system.img during compile time! I managed to make a system.img though by executing "make snod". I tried flasing that, with my userdata.img, boot.img, system.img. NOPE ,ALWAYS BRICKS!!!! Arrrgh!!!! Wtf?? Btw fastboot flashall simply does not work.
Anyway, I wish I knew how @jerpelea did it because I have tried EVERYTHING! Im super frustrated by this because it seems there is either
a) critical stuff missing to succesfully build.
b) information is way to vague.
Ive wasted a lot of time on this and Im getting tired of having to recover my phone everytime. So do yourself a favour bro and rather leave this until a proper tut is posted or someone can explain the steps in more detail.
Cheers

@NanoSurfer I compiled the ROM successfully and flashed it too. It booted up just fine. This is what I did.
I downloaded the sources of mkqcdtbootimg and then extracted the openssl libraries from Android Source and placed it in the mkqcdtbootimg source folder (place it inside libdtd folder too, not sure of the exact folder name)and typed "make". Initially I had an error regarding some linker error got it fixed by installing this package libssl-dev I'm running Ubuntu 14.04. Ok, so that resulted me in a mkqcdtbootimg executable. What I realized what while compile the compiler is calling mkbootimg when mkqcdtbootimg isn't there, so I renamed mkqcdtbootimg executable to mkbootimg and placed it in out/host/linux-x86/bin . I replaced the original mkbootimg.
Once I did that my compilation went smooth. I got all the required images in the out folder. I tried fastboot flashall that didn't work for me either. So these are the partitions are flashed manually.
1. userdata
2. cache
3. system
4. boot
5. recovery
Crossed my fingers and typed "fastboot reboot" and BAM! it booted right to the home screen
P.S. I have a Xperia Z2. I downloaded the Android Source for 4.4.4_r2 but the blobs seem to be for 4.4.2 as of now at least for Z2 so I had some issues regarding sensors. Going to change my branch and compile again. But other than that the ROM was smooth as silk

Same issues as you here are the problems I found:
1) mobile network broken
2) wifi not working
3) screen rotation not working
4) sound not working
5) brightness slider has no affect
6) internal storage showing as about 70mb
7) phone resets when restarted (like it does a factory wipe)
8) camera broken
9) Bluetooth broken
I managed to get the sound working though by flashing the aosp kernel from Sony's github I think I can fix wifi as well because I compiled the prima module, but I couldn't push it to system/lib as adb wouldn't allow it (read only file system) I'm still trying to figure out how to compile that module inline.
I think a lot of the problems are kernel related.
Interestingly tho, the performance is way better than I expected! Graphics and scrolling are very smooth.
Busy working on the issues. Will let you if I make any breakthroughs

I think I fixed the sound, just busy doing another build to test a few more things...
I'm struggling though to get the sim to work :crying: Also trying to fix wifi but I'm crossing fingers that the build I'm doing at the moment fixes that :fingers-crossed:
By the way, I was wrong previously about a few things, the data partition is actually displaying 100% correct and it doesn't reset after each boot. However, this was happening to me after I flashed a boot.img I compiled, I think maybe because I used a stock ramdisk Im just guessing but I don't know why. The kernel it builds with works just fine. If the next build is ok, I will post my device config files for others to play around with...
