: The standard location for the fallback bootloader on a FAT32-formatted EFI System Partition (ESP) is \EFI\BOOT\BOOTAA64.EFI File Format : UEFI applications are PE32+ (Portable Executable) binaries Development and Implementation

You can write a simple AA64 bootloader from scratch using the GNU-EFI library.

Secure Boot on AA64 works similarly to x86 but with key differences: aa64 efi bootloader

In practice, most AA64 servers use or the EFI stub for simplicity. Embedded AA64 (Raspberry Pi 4/5, Rockchip) often uses U-Boot that loads a separate EFI payload.

The AA64 EFI bootloader is responsible for: : The standard location for the fallback bootloader

It usually starts at EL2 (Hypervisor level) or EL1 (Kernel level).

The bootloader interacts with UEFI runtime and boot services via the pointer: The AA64 EFI bootloader is responsible for: It

If you’ve worked with x86_64 systems, you’re familiar with GRUB, systemd-boot, or even the Linux kernel’s EFI stub. But on ARM64 (AArch64, often referred to as aa64 in toolchains and firmware contexts), the boot process has its own quirks—starting with the aa64 EFI bootloader .
