SDK Image build, rootfs fails

Hello!

I just got my Luckfox Pico Plus board.
I did:
  • sudo apt update
  • sudo apt-get install -y git ssh make gcc gcc-multilib g++-multilib module-assistant expect g++ gawk texinfo libssl-dev bison flex fakeroot cmake unzip gperf autoconf device-tree-compiler libncurses5-dev pkg-config bc python-is-python3 passwd openssl openssh-server openssh-client vim file cpio rsync curl
  • ./build.sh lunch -> Pico Plus
  • ./build.sh buildrootconfig
  • Kernel - (*) Linux Kernel
  • Kernel Version - CIP SLTS 5.10.162-cip24
  • Target Packages - Networking Applications - (*) wireguard tools
  • Save - Exit - Exit....
  • ./build.sh
The compilation fails with an error say "no defconfig found" or something like this?
I tried all of the above on Ubuntu live 22.04; WSL Ubuntu 22.04 in windows; Docker; all the same error...
If i just build the image of the sdk repository without editing a thing, the image build is succesful. But i want those things above.
Obviously I'm doing something wrong because the lack of any experience at all. Can someone help me achive what i need?
My goal is to make an image which includes linux kernel and wireguard tools. My final goal is to use this board as a VPN Wireguard Server.

Hello, the kernel directory used for the kernel build of our SDK is $SDK/sysdrv/source/kernel. Buildroot is only responsible for building rootfs.img. The mainline Linux pulled in Buildroot does not support RV1103/RV1106 either. You need to uncheck the option (*) Linux Kernel.
