[Q] Compile Lollipop-Kernel topic

SOCIALIZE IT ⇨

Hi,

I just tired to compile and repack the LL-Kernel for Z1c into a boot.img.
But I can't get it to start. I only see red LED blinken when I try to boot.

I used following sources:
http://developer.sonymobile.com/down...-14-5-a-0-242/
And did it like it is mentioned in README_Xperia, which was all working fine and without errors.

README_Xperia:

Code:

Configuration files can be found in arch/arm/configs.

    Xperia Z Ultra C6802/C6806/C6833 => rhine_togari_row_defconfig
    Xperia Z Ultra C6843             => rhine_togari_brazil_defconfig
    Xperia Z1 C6902/L39h/C6903/C6906 => rhine_honami_row_defconfig
    Xperia Z1 C6943                  => rhine_honami_brazil_defconfig
    Xperia Z1 Compact D5503/M51w     => rhine_amami_row_defconfig

How to build your kernel:

  Prerequisites:

    * ramdisk.img - root fs

    * mkbootimg - boot.img generator

    * dtbTool - DTB combiner
      You can obtain it from various trusted sites including https://www.codeaurora.org/

    * The ARM cross-compiler
      Please use the arm-eabi-4.6 prebuild executable binary which is included in
      standard Android tree.


  Step 1: Build Your Kernel (zImage)
    $ cd kernel

    $ export ARCH=arm

    $ export CROSS_COMPILE=arm-eabi-
      NOTE: Please set the location and the prefix of the ARM cross-compiler.

    $ make rhine_honami_row_defconfig
      NOTE: Please set a configuration file you want to build.

    $ make

    You can see arch/arm/boot/zImage if you succeed in building the kernel.


  Step 2: Prepare Device Tree Image (dt.img)
    (In the Linux Kernel directory)
    $ dtbTool -o dt.img -s 2048 -p scripts/dtc/ arch/arm/boot/


  Step 3: Assembling the boot.img
    (In the Linux Kernel directory)
    $ mkbootimg --cmdline "androidboot.hardware=qcom user_debug=31 msm_rtb.filter=0x3b7 ehci-hcd.park=3 androidboot.bootdevice=msm_sdcc.1 vmalloc=300M dwc3.maximum_speed=high dwc3_msm.prop_chg_detect=Y" \
      --base 0x00000000 --kernel arch/arm/boot/zImage --ramdisk ramdisk.img \
      --ramdisk_offset 0x02000000 -o boot.img --dt dt.img --tags_offset 0x01E00000

./mkqcdtbootimg --kernel $KERNEL_SRC_PATH/arch/arm/boot/zImage --ramdisk ramdisk.img --base 0x00000000 --ramdisk_offset 0x02000000 --tags_offset 0x01E00000 --pagesize 2048 --cmdline "androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F ehci-hcd.park=3 msm_rtb.enable=0 lpj=192598 dwc3.maximum_speed=high dwc3_msm.prop_chg_detect=Y" --dt_dir $KERNEL_SRC_PATH/arch/arm/boot/ -o boot.img

The ramdisk.img I got from http://forum.xda-developers.com/sony...ooted-t3083764
And I extracted the boot.elf with "Andrid Kitchen", which was working almost:

Code:

7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
p7zip Version 9.20 (locale=de_DE.UTF-8,Utf16=on,HugeFiles=on,4 CPUs)

Processing archive: kernel.elf

Extracting  0
Extracting  1
Extracting  2

Everything is Ok

Files: 3
Size:       11304622
Compressed: 11308906
mv: call of stat for »3“ not possible: File or Directory not found
mv: call of stat for  »cmdline.txt“ not possible: File or Directory not found

After that there was a ramdisk.img in output folder which I used for mkbootimg.

After getting boot.img I tried to flash/load it via fastboot, which was not working. Can't figuere aout why.
Bootloader is unlocked.

Code:

fastboot boot boot.img 
downloading 'boot.img'...
OKAY [  0.349s]
booting...
FAILED (status read failed (No such device))
finished. total time: 5.437s

Code:

fastboot flash boot boot.img 
sending 'boot' (11044 KB)...
OKAY [  0.349s]
writing 'boot'...
FAILED (remote: Command not allowed)
finished. total time: 0.352s

And because of that I tried to flash it via TWRP/CWM/... with following updater-script:

Code:

show_progress(0,0);
ui_print(" flashing boot.img...");
package_extract_file("boot.img", "/dev/block/platform/msm_sdcc.1/by-name/boot");
ui_print(" finished");
show_progress(10.000000, 1);

So maybe anyone can point me to mistake I make?
