How to build only kernel?

[DavidJS]

Yes, this is another rookie question: if I only modify the dts file of the kernel or a certain part of the driver code, I run ./compile.sh, need to wait a long time for the compilation process of uboot and various libraries. How can I only compile the kernel part?

I see there is a compile option: KERNEL_ONLY, is this possible? How do I need to update the kenel part after compiling?

[Werner]

If you use the menu to choose to build packages only it is the same as using KERNEL_ONLY. This will build kernel image, headers, dtb and uboot packages but not a whole image.

Use these packages on your board and install them via dpkg.

[DavidJS]

@Werner, thank you . So I can config KERNEL_ONLY to be yes, and use dpkg to install the .debs.

[Werner]

Yes.

 

Keep in mind that user built images/packages are unsupported. So if you run into trouble like unexpected behavior after installation or inability to boot you are on your own.

Create proper backups before tinkering.

if your board is running armbian, and you want to rebuild kernel, I suggest to build kernel natively.

here is handbook https://kernel-team.pages.debian.net/kernel-handbook/

 

you need to patch debian kernel before build.
