If you use "-kernel" and it's not an ELF file, then we assume it's a Linux kernel image with the arm64 Linux image header format. Since in your case this probably isn't true, we're crashing very early on. You probably want: (1) to pass the ELF file directly to QEMU rather than converting it to a binary (2) to make sure your image is linked correctly to work with the "virt" board's memory layout, which is different from that of the Foundation models thanks -- PMM
