I'm trying to build a kernel driver for 5.7.14 for my custom image but couldn't find a linux-source package for the kernel version at https://mirrors.netix.net/armbian/apt/pool/main/l/
I tried to use armbian-config but it didn't show it, either (5.4.44 was listed instead).

Where can I get 5.7.14 source code?

I checked out Armbian Build v20.05( https://github.com/armbian/build/releases/tag/v20.05 )and created an image with the following options:

BOARD=tinkerboard RELEASE=buster BRANCH=current BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no INSTALL_HEADERS=yes BUILD_MINIMAL=yes

The system information is as follows (on Tinker Board):

root@tinkerboard:~# cat /etc/armbian-release 
# PLEASE DO NOT EDIT THIS FILE

I also found weird stuff in install.log. I checked out v20.05 but the log said the build.sh was installing v20.08.
I'm missing something. What is it?

# output/debug/install.log

dpkg-deb: building package 'armbian-firmware' in 'armbian-firmware_20.08.0-trunk_all.deb'.

Any suggestions are appreciated.

Thanks.

If the sources are missing and you may want to build your own image anyways I'd do this:

BOARD=tinkerboard BRANCH=current KERNEL_ONLY=yes KERNEL_CONFIGURE=no

To get a complete set of packages including kernel image, kernel source, kernel headers, dtbs and U-Boot.

I checked out v20.05

You need to create a file .ignore_changes in the build directory. Not sure if this is a bug ... but this way it will remain on a checked bnanch.

 

But anyway - sources will not be in the repository since we don't build and host sources for each upstream version. If you need the exact version, build image (upgrade deb pack) with BUILD_KSRC="yes" I think default is to build it. https://docs.armbian.com/Developer-Guide_Build-Options/

But wont be pre-installed on the image. Just to mention...

INSTALL_KSRC="yes" and they should be:

Just now, Igor said:

INSTALL_KSRC="yes"

 

Well that flag isn't documented. I'll fix that.

I found it in the document after posting this and now I've being trying it, thanks.

INSTALL_KSRC="yes"

I will try this option as well later on.

Putting the .ignore_changes did work fine.
The original title was a little bit wrong. What I wanted to do is to build a v20.05 image and to get its kernel source code (the actual version is 5.4.57 rather than 5.7.14).

The correct way to do it is

1. Clone the master (https://github.com/armbian/build.git)
2. Run vagrant if necessary (cd ./config/templates; vagrant up; vagrant ssh; cd armbian)
3. Run sudo git checkout origin/v20.05
4. Run sudo touch  .ignore_changes
5. Run ./compile.sh BOARD=tinkerboard RELEASE=buster BRANCH=current BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no INSTALL_HEADERS=yes BUILD_MINIMAL=yes INSTALL_KSRC=yes

And the following file was created under output/images.

Armbian_20.05.7_Tinkerboard_buster_current_5.4.57_minimal.img

The image file includes a src archive file on /usr/src.

root@tinkerboard:~# ls /usr/src/
linux-headers-5.4.57-rockchip  linux-rockchip-current_5.4.57_20.05.7_config.xz  linux-source-5.4.57-rockchip.tar.xz

Thanks guys.
