Bootloader

When the 3DS does not find the NAND chip, the following error is displayed:

The 3DS' Boot procedure:

• 0 Seconds - unit is powered on bootrom begins execution

• 2 Seconds - bootrom attempts to initialize the NAND. If the NAND is successfully initialized, the bootrom launches the firmware loaded from the NAND FIRM partition which handles booting the rest of the system. The ARM11 kernel loaded from FIRM then loads the CXI ARM11 system modules embedded in the kernel. If the NAND cannot be initialized, (i.e. the NAND chip is not connected/damaged etc) a blue error screen similar to the screen above appears.

• 3 Seconds - all essential hardware is active. PM loads NS, which then loads the current active menu. For retail units this menu is usually the Home Menu.

• 4 Seconds - the LCD screens are initialized

• 7 Seconds - Home Menu is fully initialized/loaded
