Make kernel-config does not work on current github fenix

Technical Support
1

I am using Ubuntu 20.04LTS on a Desktop to build the Khadas Linux image. I can configure and run make and it generates a complete image based on ./fenix/build/linux_mainline-5.12.

If I run make help from the ./ folder, I get the help indicating I can build the kernel separately. I can run make kernel and it makes the default kernel.

Now I want to make changes to the default kernel and so I run make kernel-config. It returns cp: cannot create regular file ‘/home/ubuntu/fenix/build/linux-mainline-*/.config’: No such file or directory.

One of the scripts seems to be wanting to copy a single file into a wildcard or there is an environmental variable not set. I have searched through files, but the khadas build is so extrapolated that I cannot find the location.

I want to set custom options which I can set inder ./fenix/build/linux-mainline-5.12/make menuconfig
Once finished it writes it to ./fenix/build/linux-mainline-5.12/.config. However when going to ./fenix/make kernel it overwrites the .config again with defaults. I presume the “make kernel-config” allows me to overwrite the defaults but it does not work.

Please help

Tanks for your feedback. We will check this issue.

Could you suggest a workaround in the meantime please. I want to just build the kernel after changing kernel drivers, specifically usb_serial_option.

Thank you

yes

tnx will be fixed !!!

hi @numbqq , I have used your patch.https://github.com/khadas/fenix/commit/047d9953235120f81f57ca9d15f374f9d257319b.
but,it do not work.

Any idea?

Can you try this?

$ make kernel-config
$ make kernel-saveconfig

I can copy build/linux/defconfig to build/linux/arch/arm64/configs/kvims_defconfig manually. but make kernel-saveconfig can’t work.

Are you sure you use the latest code from our GitHub and don’t have other modifications? It works well on my side.

Still error. See below history what I did:

177 mkdir project
178 cd project/
179 git clone --depth 1 GitHub - khadas/fenix: One-stop script set to build Ubuntu/Debian images
180 cd ~/project/fenix
181 source env/setenv.sh
182 make help
183 make kernel-config

It then ran though a number of steps and failed here

THIS IS THE SETUP:
4. VIM3
2. uboot-mainline

  1. linux-mainline
  2. Ubuntu
  3. focal
  4. minimal
  5. SD
    N. Do not compress

if I however add this line in ./fenix/config/functions/build
LINUX_DIR=/home/ubuntu/dashcam/fenix/build/linux-mainline-5.12

then it works. So it appears that LINUX_DIR is not setup correctly.

sorry your right - need to improve it :wink: plz wait we can fix it very soon

at this moment just simple solution is

# need only 1st time) can break by Ctrl+C after downloading kernel source 
make kernel
# after can run it already
make kernel-config
14

ok fixed!
now u can do make kernel-config at any time
