Hi Valdis, and all, I tried it again, but I had error with aarch-linux-gnu- . So I changed it with export ARCH=arm64 export CROSS_COMPILE=aarch64-none-elf- and then, make defconfig make vmlinux and vmlinux was generated. So the kernel was built with aarch64-non-elf- toolchain as I thought normal. Maybe last time there was some mistake.. Thank you!
