+ | The '''TYPE''' tag is a 32-bit unsigned integer (<code>uint32_t</code>) that, when viewed in little-endian format, states the type of firmware image the IMG2/[[IMG3 File Format|IMG3]]/[[IMG4 File Format|IMG4/IM4P]] file is. This value is passed to <code>load_selected_image</code> and then <code>[[Image load|image_load]]</code> early in the [[BootROM|SecureROM]] boot process, where a non-NULL pointer check is performed. |

− | Contains a fourcc denoting the "type" of firmware image it is. Compared with R1 of [[image_load]](); when verifying the image. If it does not match, image_load(); will fail and the image will not be loaded. If R1 to image_load(); is zero, then all types are allowed. |

The TYPE tag is a 32-bit unsigned integer (uint32_t
) that, when viewed in little-endian format, states the type of firmware image the IMG2/IMG3/IMG4/IM4P file is. This value is passed to load_selected_image
and then image_load
early in the SecureROM boot process, where a non-NULL pointer check is performed.
