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? 

Linux orangepizero2 6.12.20-current-sunxi64 #1 SMP Sat Mar 22 19:54:28 UTC 2025 aarch64 GNU/Linux

linux-headers-current-sunxi64/bookworm,now 25.2.3 arm64 [installed]
  Armbian Linux current headers 6.12.20-current-sunxi64

linux-image-current-sunxi64/bookworm,now 25.2.3 arm64 [installed]
  Armbian Linux current kernel image 6.12.20-current-sunxi64

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 ?
