Here's the problem:
I download the cm 11 source (kitkat), mkvendor, create the device tree, create every needed file and I compile it and I get a black screen that blinks static when I touch it.
Phone: Samsung GT-S7560(trend)
What is going wrong? I don't get it
I have graphics.c and BoardConfig right. I use the stock kernel for the cwm (prebuilt one got from boot.img)

Hello To All
This no longer when I managed to start kernel development.I used this source for compiling (my device is Gio).This is a custom kernel with cf-root and this is for GB roms.Used 2009q3 toolchain for compiling.I have went to the source dir and typed this:
make gio_defconfig
and configs done(i used config which was in the source not taken from another kernel).Then i typed to compile.when the compiling completed repacked zimage and its modules with a cm7 ramdisk kernel which was made by same dev(the person whom i got source from his githube)
when i flash the kernel it shows samsung logo then shows white screen (bootloop)
need devs help.I even tried a stock ramdisk but no result.
I need devs help.expect more
Hello. in this moment i have problem with kernel. on ubuntu i make it for my Alcatel ot-908 but after flash kernel doesn't work (black Screen) I Get source kernel , add Patch and Governor form : http://forum.xda-developers.com/showthread.php?t=1748297 and i Decompile old boot img and Change zImage from http://forum.xda-developers.com/showthread.php?t=915808 but i don't know what is bad.I use arm-eabi-4.4.3 becouse arm-eabi-linaro-4.6.2 doesn't compile. Is a method which I Can Look Errors in boot (like logcat in adb) ?
Hello,
since I don't yet have access for the specific section I post here
I can't find how to flash a kernel built from source (aka zImage). Since fastboot is not available on GS3, I just want an alternative tech to boot my gs3 with my build zImage.
I build the source from stock kernel samsung opensource database (update 8) and receive a zImage file.
I made a backup with cwm and unpack the boot.img with a perl script, then repack a new boot.img with my zImage as kernel and the ramdick from unpack but cannot boot with new package.
Could someone maybe give me a kernel source and the right corresponding package to boot it. Or maybe just a good way to make the whole process.
My final goal is to build a custom module for the GS3, that's my I need building from source and not an already-packed-kernel. Moreover if someone can help me directly about the module, he's very welcome
Hello xda,
I am new into kernel development.Recently I downloaded the kernel sources for my phone Zenfone 2 Laser -ZE550KL
After that I compiled the stock kernel, since It is based on arm64 I got a file named Image instead of zImage.
After searching I found a way to convert that to a boot.img (using the ramdisk from stock kernel).I could get the kernel to boot on the device using
Code:
fastboot boot boot.img
The device booted successfully with the kernel, I could see change in the name of Kernel in About Phone.
But the problem is Wifi/Bluetooth and Soft keys do not work.Wifi turns on But cannot see any AP.
BT works(A BT enabled watch vibrated )but no device can be seen in bletooth settings.
Please help me with this kernel.
here is the link to my source=>
https://github.com/abhishekr700/ZE550KL_KERNEL
I am using ze550kl_defconfig present in /kernel/arch/arm64/configs to make .config file for building kernel.
Thanks.
