I've seen discussions about this topic, such as this one. But I'm still confused and got errors when configuring the kernel after set the Yocto options as stated. I'm running PetaLinux 2020.1 and my downloaded sstate files are in /opt/xilinx/PetaLinux/2020.1/sstate, in which I have 3 folders: arm, aarch64, and downloads (empty).
1. What is the pre-mirror url pointing to? Should it be an empty/writable folder or should I put something inside? I pointed it to /opt/xilinx/PetaLinux/2020.1/sstate/downlods.
2. I pointed local sstate feeds url to /opt/xilinx/PetaLinux/2020.1/sstate/arm for my zynq project.
3. I selected Enable BB NO NETWORK.
4. When running petalinux-config -c kernel, I got errors:

Should I download something else (linux-xlnx.git.tar.gz?) as well to make petalinux to work offline completely?
