 Compile
Android kernel from the source I
confirmed the following procedure only on my linux host (FC8). Sorry
for Windows and Mac users.
1. Get toolchains from CodeSourcery (Choose ARM EABI and IA32 GNU/Linux). 2. Get kernl source code from here. 3. Deploy toolcains and kernel source and enter in the kernel source tree. $ mkdir -p android $ cd android $ tar xjvf ../arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 $ tar xzvf ../linux-2.6.23-android-m3-rc20.tar.gz $ cd kernel 4. Get the config.gz from the running emulator by the following way. $ adb pull /proc/config.gz . 5. Decommpress the config.gz and rename it as .config $ gunzip config.gz $ mv config .config 6. Specify CROSS_COMPILE in the Makefile. CROSS_COMPILE=../arm-2007q3/bin/arm-none-linux-gnueabi- 7. Comment out LDFLAGS_BUILD_ID[*1] in the same Makefile. #LDFLAGS_BUILD_ID = $(patsubst -Wl$(comma)%,%,\ $(call ld-option, -Wl$(comma)--build-id,)) 8. Make the kernel $ make 9. Check zImage is created and the size is nearly same as the kernel-qemu in the Andorid SDK. $ ls -l arch/arm/boot/zImage -rwxrwxr-x 1 motz motz 1234712 2007-12-01 18:06 arch/arm/boot/zImage $ ls -l $SDK/tools/lib/images/kernel-qemu -rwxrwxr-x 1 motz motz 1245836 2007-11-12 5:59 ...sdk/tools/lib/images/kernel-qemu 10. Run emulator with the created kernel. $ emulator -kernel arch/arm/boot/zImage Motz |
