3.10.2 Image Flags

The image flags of the header define various bit options that control how the image will be
executed.

Table 3-2 MOTLoad Image Flags

Name
COPY_TO_RAM
IMAGE_MCG
IMAGE_POST
DONT_AUTO_RUN
COPY_TO_RAM
If set, this flag indicates that the image is to be copied to RAM at the address specified in
the header before control is passed. If not set, the image will be executed in flash. In both
instances, control will be passed at the image offset specified in the header from the base
of the image.
IMAGE_MCG
If set, this flag defines the image as being an Alternate MOTLoad, as opposed to USER,
image. This bit should not be set by developers of alternate boot images.
IMAGE_POST
If set, this flag defines the image as being a power-on self-test image. This bit flag is used
to indicate that the image is a diagnostic and should be run prior to running either USER or
MCG boot images. POST images are expected, but not required, to return to the boot
block code upon completion.
