[HOW-TO] Build your own kernel package from source

[Jerry Hildenbrand]

i dont have an htc but in my search for an answer has led me to you and this place of knowledge....


trying to do the repo init and instead of going to ~/droid folder it keeps trying to go to my /home/jarvis. any idea on how to change which folder the repo tries to go to. im running 9.10 so if you dont know thats ok nobody has seemed to have the answer. thanks for reading.

jarvis@jarvis:~$ cd ~
jarvis@jarvis:~$ mkdir mydroid
jarvis@jarvis:~$ cd mydroid
[COLOR="Red"]mkdir bin
curl http://android.git.kernel.org/repo > ~/bin/repo
chmod a+x ~/bin/repo

~/bin/repo init -u git://android.git.kernel.org/platform/manifest.git -b eclair
~/bin/repo sync[/COLOR]

jarvis@jarvis:~/mydroid$ repo init -u git://android.git.kernel.org/platform/manifest.git -b eclair

Your Name  []:

Your identity is:  <>
is this correct [yes/no]? yes

[B][I]repo initialized in /home/jarvis[/I][/B]<---- the issue
jarvis@jarvis:~/mydroid$

Have a look at what I added in red in your code. Are you grabbing the repo script from android.git.kernel.org and putting it in ~/bin, then using that script in your sync?

HowTo: Set up For Development in Ubuntu 9.1 (thanks denkai) - ModMyMoto - Software Modding Forums and Updates for Motorola Phones

i was following that tutorial. so i was making the bin before this and there is a a bin dir in my home that has repo in it. someone on a git google group mention i should try

rm -rf ~/.repo

thinks i may have install repo to my home file at one point.

really appreciate your help here. thanks a ton. just someone looking at it is awesome. i was also thinking of just reinstalling 8.0.4 and starting fresh

 

[dougpiston]

rm -rf ~/.repo

just so you all know this fixed my issue... im now stuck elsewhere but i will fix it

SO to clarify, you may have mistakenly placed the repo script in ~/, and just had to delete that entry and add it in the correct place? (~/bin)

Knowing what mistakes look like and what fixes them is handy info.

thats exactly right. now just getting hung up on a command after you dl'd a vendor tree..

I'd like to give a great big thanks to gbhil. Using this guide I have made my own custom kernel based off of gumbo 1.5c to include the overclock modification posted in XDA forums!

 

[srkmagnus]

Man, too bad I don't have Linux and really dont' want to risk messing up my Mac by running Linux alongside osx Good write-up Gbhil, hopefully I can get around to incporating this and get deeper with Android.

 

[Andrew Ruffolo]

you can use parallels if you already have that.

 

[krysalicea]

hey i need help i am on step 6 and i am entering......adb pull and its not reading it as a command. how can i fix this?

 

[David Fisher]

Thanks for your info very much!

I followed you with my HTC Desire. I tied to compile this kernel but get the following build error.

Code:

CC drivers/mtd/nand/nand_ids.o
LD drivers/mtd/nand/built-in.o
LD drivers/mtd/onenand/built-in.o
LD drivers/mtd/tests/built-in.o
LD drivers/mtd/built-in.o
CC drivers/net/mii.o
make[2]: *** No rule to make target `drivers/net/kineto_gan.o', needed by `drivers/net/built-in.o'. Stop.
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2

However,after I
change
[*] Networking support --->
to
[ ] Networking support --->
I successed.But,this is not a good idea.Because the Networking is not supported.Do you have any good resolution?

 

[David Fisher]

I've tried to compile this kernel but get the following build error. Has anyone else had this?

Code:

CC drivers/mtd/nand/nand_ids.o
LD drivers/mtd/nand/built-in.o
LD drivers/mtd/onenand/built-in.o
LD drivers/mtd/tests/built-in.o
LD drivers/mtd/built-in.o
CC drivers/net/mii.o

make: *** [drivers] Error 2

Thanks for the great tutorial gbhil, works great.

this is for eveyone it is the entire tutorial in pdf for for easy access from anywhere all links included.
gbhill feel free to post it for others to have

Right click and do "save target as"

Trying to use this to create my first kernel for the optimus T, I know I probably shouldn't use an htc guide for an lg device, but this is the best tutorial I've seen (blatant ass kissing). So I'm using Ubuntu 9.10, because in the LG source it says 9.10 compile environment, and I downloaded java6 to match it, everything seems to go fine until putting the zimage in the boot.img, if I try to use flash_image boot /sdcard/zImage with the kernel it created, I get stuck in fastboot. If I follow the tutorial straight through and use flash_image boot /sdcard/myBoot.img, I get about 25 memory errors and a non-booting phone. So are the scripts to extract the kernel & ramdisk for the Hero only, or am I doing something (probably several things) wrong?

 

[Joeseph Mother]

Decided to start over, now I get the same error every time I run make. Any ideas?

when you repack the boot image, you need to correct memory space address (the base -- XXXXXXXXXX number) for the phone your working on. Get the right base address and the rest of the script should be just fine. Look in the kernel source here:

arch\arm\mach-msm\include\mach\memory.h

and find the section

 /* physical offset of RAM */

You should see a number for define PHYS_OFFSET, thats your base address.

Try a "make clean" again

In memory.h, no number is present, I have:

/* physical offset of RAM */
#define PHYS_OFFSET UL(CONFIG_PHYS_OFFSET)
#define MAX_PHYSMEM_BITS 32
#define SECTION_SIZE_BITS 25
#define HAS_ARCH_IO_REMAP_PFN_RANGE
#ifndef __ASSEMBLY__

On my current setup everything is back to where it was last time (had to specify cross compile, toolchain, eabi path before clean), so I just need someone a lot smarter than me to figure out how to get my zimage loaded into the boot image. I know the zimage is good, because when I put it in the update.zip that drellidee put out, it boots fine. Thanks a lot for the help, I know idiots like me asking stupid questions can get irritating.

adb pull /proc/config.gz Not Found

Hey all im trying to follow this tutorial and when i run the adb pull /proc/config.gz command it returns 'not found'. ive tried this on aospMOD_0.9.9.2 and the stock 2.27.651.5 from htc.

is this needed and if so how can i get it?

thanks in advance

 

[asadullah]

I just downloaded the source for the lg optimus m from their site so that I could find the base address. I unzipped it but there wasn't a PHYS_OFFSET in there. Any clues do I have to do something else

nevermind it's

CONFIG_PHYS_OFFSET=0x12200000

@josephmother in your output where you put,"#define PHYS_OFFSET UL(CONFIG_PHYS_OFFSET)" the words in parenthesis tell you where the PHYS_OFFSET is. So look in your config that you pulled and your base address will be

I just tried it on a sprint hero running a custom version of 2.27.651.5 (only things different is it's been flashed to metro pcs and has a custom boot image and kernel) I typed this into terminal

adb remount
adb pull /proc/config.gz

it pulled it fine. The changes I made wouldn't affect whether it was there or not

I'm having some problems following this for my Huawei U8150 running Froyo.

Problem 1: I'm unable to extract the ramdisk from the boot.img file. It complains about it not being gzipped.
Problem 2: I'm not really sure if I'm using the right wlan.ko file for this. My phone doesn't appear to have one, but it does have a system folder in the ROM that includes a wifi folder and a "ar6000.ko" file. Should I rip that out of my existing ROM?
