How Would I Build a Kernel Using My Own "initramfs.cpio.gz" (JB4.3_1.1.0 GA)

[freewaymad]

Hi,

How would I build a kernel using my own "initramfs.cpio.gz" (JB4.3_1.1.0 GA) ? I am not sure what to change on the "gen_initramfs_list.sh" to point to my "initramfs.cpio.gz" file.

Please help,

Thanks,

What I found,

Take the initramfs.cpio.gz and unpack it (assuming it is compressed). Take initramfs and extract it from the .cpio. You now have the folder with your files in it.  I named mine "cpio". Put it in the "kernel_imx folder. Open a terminal follow the procedure to build a kernel:

$ export PATH=~/mydroid/jb/bootable/bootloader/uboot-imx/tools:$PATH

$ cd ~/myandroid/kernel_imx

$ export ARCH=arm

$ export CROSS_COMPILE=~/mydroid/jb/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

$ echo $ARCH && echo $CROSS_COMPILE

$ make distclean

$ make imx6_android_defconfig

Now type:

$ make menuconfig

A menu will come up. Select "General Setup" then select "Initramfs source files". Type in the full path to folder; an example of this:

/home/base/myandroid/kernel_imx/cpio   (assuming the folder is named "cpio")

select "ok" then "exit" then "exit" again. You will get this in the terminal:

*** End of the configuration.

*** Execute 'make' to start the build or try 'make help'.

Type:

$ make uImage

With a successful build, the generated kernel image is ~/myandroid/kernel_imx/arch/arm/boot/uImage.

Every time the "make distclean" is used, the configuration will be cleared. So, it will have to be reset if you want to use it again.
