Replace the prebuilt kernel in the Android Platform Source

Question

I have successfully built and run a version of the goldfish kernel in the emulator. What I want to do now is include this in the platform source I have. So that I can build and run the platform from scratch with my custom kernel.

I have looked everywhere for help in replacing the kernel that is already there. I believe I need to change the 'TARGET_PREBUILT_KERNEL=' line in a build file somewhere but I can't find the right place.

Any help would be much appreciated.

You don't need to change the configuration files. You can override them at the command line. If you export TARGET_PREBUILT_KERNEL="Path to my zImage" and then build the platform. When you build the platform, it will use your zImage as part of mkbootimg instead of the default.

However, if you did want to change this its under $(ANDROID_ROOT)/device/<my device>/device.mk.

So if you were building for the Galaxy Nexus, you would modify the file device/samsung/tuna/device.mk.
