1. Kernel configuration files
arch/arm/configs:
Nokia 1 (TA-1047/TA-1060/TA-1056/TA-1079/TA-1066): FRT_defconfig
2. How to build
Prerequisites:
* ramdisk.img - root fs
* mkbootimg - boot.img generator
* 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 Kernel (zImage)
$ cd kernel-3.18
$ export ARCH=arm
$ export CROSS_COMPILE=<cross compile path with prefix>
NOTE: Please set the location and the prefix of the ARM cross-compiler.
Please use the absolute path for this.
ex) <cross compiler path>/prebuilts/gcc/linux-x86/arm/arm-eabi-6.3.1/bin/arm-eabi-
$ make FRT_defconfig O=<output path>
NOTE: Please set a configuration file you want to build.
$ make O=<output path>
You can see arch/arm/boot/zImage-dtb if you succeed in building the kernel.
Step 2: Assembling the boot.img
(In the output directory)
$ mkbootimg --kernel arch/arm/boot/zImage-dtb --cmdline "bootopt=64S3,32N2,32N2 buildvariant=userdebug" \
--base 0x40000000 --kernel_offset 0x00008000 --ramdisk_offset 0x04000000 --tags_offset 0xE000000 \
--ramdisk ramdisk.img --output boot.img
