You need a boot image, not just a kernel. This might be helpful: http://glandium.org/blog/?p=2214 I actually compile my kernel using the toolchain from AOSP, e.g. CROSS_COMPILE=/path/to/aosproot/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- If you are in fact building and flashing AOSP, you can point the AOSP build process to your own kernel and wifi module and have it package them up as part of the boot.img that is normally produced rather than the prebuilt ones under device/samsung/crespo by specifying TARGET_PREBUILT_KERNEL and TARGET_PREBUILT_WIFI_MODULE on the make command line or customizing the device_base.mk file. -- Stephen Smalley National Security Agency -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
