If it's the version from Ubuntu 18.04, that is now really quite old, so I would start by trying a newer QEMU. You should also use a newer Ubuntu, because (a) 18.04 is no longer supported as a build platform for current QEMU and (b) 18.04 fell out of security support last year, so you're already overdue to migrate away from it. If nothing else, a newer QEMU has improved that particular error message so it gives better detail about exactly what binary blobs are overlapping and causing the problem. thanks -- PMM
I Failed to execute AARCH64 Linux kernel on the QEMU
Hello. I'm trying to execute AARCH64 Linux kernel on the QEMU. But,there was an error and the error log is: > rom: requested regions overlap (rom bootloader. free=0x422c0a00, > addr=0x4000) > qemu-system-aarch64: rom check and register reset failed > > And my development environment is: > host: x86_64 Ubuntu 18.04 > linux kernel source version: v5.19 > busybox version(for initramfs): 1_36_stable > > I cannot find what I should check first. I mean, I'm lost. So, I need help. What I did to achieve my goal is as following: 1. Linux kernel build for AARCH64 - apply defconfig > make ARCH=arm64 defconfig -j$(nproc) CROSS_COMPILE=aarch64-linux-gnu- > > - set 'CONFIG_BLK_DEV_RAM' config by using menuconfig to use RAM disk - build kernel > make ARCH=arm64 -j$(nproc) CROSS_COMPILE=aarch64-linux-gnu- > > 2.
