CONFIG_MULTIBOOT
¶
Generate multiboot header
Type: bool
Help¶
Embed a multiboot header in the output executable. This is used by some boot loaders (e.g., GRUB) when loading Zephyr. It is safe to leave this option on if you’re not sure. It only expands the text segment by 12-16 bytes and is typically ignored if not needed.
