Need Kernel source for linux-image-current-sunxi64 6.12.20

[ovacikar]

Hi, I need linux kernel source to compile a custom module. The one I downloaded from kernel.org did not work, got module format error, indicating the kernel is different.

i did not have this problem compiling the same module for Armbian lepotato (amlogic)

 

Where do I get the kernel source for my Orangepi Zero 2?

We just figured out we have dropped packing kernel sources at some point. Until we figure out how to re-enable that or if this makes sense, use build framework to add a custom module. It has the ability to do that.

Allwinner kernel is heavily patched, version is not necessarily latest, quite distanced from mainline, while Amlogic, on the other hand, is closer, changed less.

I set the version in userpatches/lib.config , then executed this:

./compile.sh BOARD=orangepizero2 BRANCH=current kernel-config KERNEL_BTF=no KERNEL_GIT=full

 

and when the kernel menu came up, just exited to shell.  Is this the kernel source directory I can point the compiler script of the module ?

The kernel headers that you have installed are quite enough to build the kernel module, the source codes of which you have.

 

If the source codes are already in the kernel, then you just need to configure the kernel before compiling.
launch:

./compile.sh BOARD=orangepizero2 BRANCH=current kernel-config

After you finish the configuration, the build system saves your configuration file (it will tell you where it did it).
Save it under the name ./config/kernel/linux-sunxi64-current.config

It is assumed that you are in the armbian/build directory.

launch:

./compile.sh BOARD=orangepizero2 BRANCH=current kernel

This 3rd party module needs both kernel headers and kernel source. The Makefile bundled with the code applies patches to an existing  kernel module source code and compiles it.

 

I ran the build script on a separate debian vm and created a tarball of the source tree. i will try to transfer it to the opi later today.
