General :: Porting A Kernel That Hangs At Boot
Feb 1, 2014
I am trying to port a kernel from one zte 8960 to another. I have cwm recover set up with kexec to get a log of what is going on. the kernel hangs at boot of the phone so I trying to find the cause
-last_kmsg after a failed boot of 3.4
pastebin.com/0AGpACsT
-last_kmsg after a boot of 3.0.8
pastebin.com/N3WtDHwC
-split-boot of boot.img
Code:
output directory: fi
boot_magic correct: ANDROID!
kernel size: 6045264
kernel address: 2149613568
Base: 2149580800 (hex): 0x80200000
[code]....
I am thinking it might had hit "un-allocated" memory area, I did have to change the ramdisk_offset from 0x01300000 to 0x02000000 make the kernel fit. what could I do to check to see if it is un-allocated space I am dealing with

I am trying to do some low level performance testing related to device processor cores through adb which I feel it is affected by Android background services and system stuff.
As I know that the Android boot sequence stages are as follow:
1.Execute Boot ROM code.
2.Execute the boot loader.
3.Load the Linux kernel.
4.Launch Zygote, which initializes the Dalvik VM.
5.System server which loads the Android system.
So my question is how can I interrupt this sequence to force it stop on stage 3 to load Linux kernel. This can implement my intermediary performance testings before loading again Android system.
Does Fastboot or Clockworkmod recovery can load my device to a kind of Linux kernel?

Samsung Galaxy 7.0 plus (gt-p6210) will not boot. It hangs at the Samsung banner. The banner is still glowing but it goes nowhere.
I have tried everything.
a. Delete cache (dalvik and otherwise)
b. System wipe.
c. Removed add on sim and repeated above.
I have a rooted ICS (original install via Kies).

I am trying to use my cheap virtually unbrickable tablet to learn more about kernel development and eventually ROM building.
I have extracted the manufacturers (WoPad) LiveSuit image and used split_bootimg.pl to break up the boot image.
I extracted the config file from the kernel image using extract-ikconfig and it created a config file. I didn't see the config in /proc.
So, I have the factory ramdisk and the factory kernel config.
I have downloaded several kernel sources (lichee-3.0.8, ChritianTroy's 3.0.36, and another one from linux-sunxi 3.0.72). I can successfully compile all of them without errors and they all generate zImages, uImages, etc using the factory config as well as the sun4i_crane configs they come with.
When I repack the boot.img with the newly created kernel and install it on nandc it wont' boot past the android icon (u-boot). When I compare my boot.img to the factory one, they both have the same offset where the kernel starts (0x00000800). I have also ensured I'm replacing the kernel modules when I'm changing kernel versions.
Here is the line I'm using to repack the boot.img
Code:
mkbootimg --base 0x40000000 --pagesize 2048 --kernel zImage --ramdisk ramdisk-repack.cpio.gz --board sun4i --cmdline "console=ttyS0,115200 rw init=/init loglevel=8" -o boot.img
[Code]...
Also, I'm building on Ubuntu 13.04 with Google GCC 4.6 from the ndk. I have built kernels for other devices without issues.

Android Version: 2.2 [Optional]Are You rooted & which Rom: Rooted and flashed to "[ROM] Official 2.2 (HTC 2.09 and 2.10): busybox, A2SD+, TUN, EXT4, Undervolt, SYSRW"
Issue: I've flashed to another ROM and now want to restore my back-up that I made via Clockworkmod. The restore seems to do fine, but when I reboot my phone hangs at the boot screen.
In the meanwhile I have flashed the recovery from clockwork to AmonRa. To restore the clockwork back-up, I boot into clockwork recovery via ROM Manager. Maybe I should reflash to clockwork, but that didn't work till now.

I wanted to change the boot logo for i9300. Im well aware that you have to incorporate it in the kernel. I installed Ubuntu, the necessary libraries and brought the cyanogenmod source code. Only part is I dont have the necessary experience to tweak it using the NDK tools

I have a samsung galaxy young s6312. My phone has stock android 4.1.2 jellybean. I rooted it with framaroot using gandalf exploit. Its been 2 days since I rooted my phone, and it has freezes four times in these two days. By freezing, I mean that when I am playing a game, it suddenly stops responding and the screen goes black. I have to take the battery out and reinsert it. This never happened to me with my non rooted phone.

I'm having some problems with the porting of a rom, my phone is a clone of the phone from which i'm taking the rom (My phone is a NGM Legend 2, which is also a clone of Gionee GN868, and the original is Blu Vivo 4.3) the only thing which is really different are the mounting positions of the internal memory.
In Blu Vivo 4.3 the system partition is mounted on /dev/block/mmcblk0p3 and the data partition is on /dev/block/mmcblk0p5 while in the mine they are mounted on /dev/block/mmcblk0p4 and /dev/block/mmcblk0p6.
I changed them in the updater-script so i'm able to install the rom, but i had to replace the boot.img with the one from my rom because the phone wasn't booting up, but i can't install any app from google play store (error 110) or any apk ("app not installed" error).
