 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.
 DONT_AUTO_RUN
If set, this flag indicates that the image is not to be selected for automatic execution. A
user, through the interactive command facility, may specify the image to be executed.
6.7.3 User Images
These images are user-developer boot code; for example, a VxWorks bootrom image. Such
images may expect the system software state to be as follows upon entry:
 The MMU is disabled.
 L1 instruction cache has been initialized and is enabled.
 L1 data cache has been initialized (invalidated) and is disabled.
DONT_AUTO_RUN 0x00000008 Image not to be executed
Table 6-2 MOTLoad Image Flags (continued)
Name Value Interpretation
MOTLoad currently uses an Image Flag value of 0x3, which identifies itself as an Alternate
MOTLoad image that executes from RAM. MOTLoad currently does not support execution from
flash.
