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
We recommend getting the CodeSourcery Lite compiler.
Or, you can also use prebuild executable binary which is included in
standard Android tree.
Step 1: Build Your Kernel (zImage)
$ cd kernel
$ export ARCH=arm
$ export CROSS_COMPILE=/opt/arm-2010q1/bin/arm-none-eabi-
NOTE: Please set the location and the prefix of the ARM cross-compiler.
$ make shinano_leo_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
