Default Build

For a default build, just run:

 bitbake virtual/kernel

After done, you can collect the built image from under the deploy folder, for example: build/tmp/deploy/glibc/images/vmware/bzImage-vmware.bin.


Kernel image type

What kind of kernel image to build is controlled by the variable KERNEL_IMAGETYPE. For example, build image for u-boot

 KERNEL_IMAGETYPE = "uImage"

Kernel configuration

The default .config file used is placed in ???/defconfig.


If you need to customize the kernel configuration, run the menuconfig task by:

 bitbake -c menuconfig virtual/kernel

Note: by default this command requires you to run in X Windows.

After that, you can compile the kernel by:

 bitbake -f -c compile virtual/kernel
