Startup Sequence

The firmware startup sequence following reset of MOTLoad is to:
 Initialize cache, MMU, FPU, and other CPU internal items

Initialize the memory controller
 Search the active flash bank, possibly interactively, for a valid Power On Self Test
(POST) image. If found, the POST images executes. Once completed, the POST
image returns and startup continues.
 Search the active flash bank, possibly interactively, for a valid USER boot image.
If found, the USER boot image executes. A return to the boot block code is not
anticipated.
 If a valid USER boot image is not found, search the active flash bank, possibly
interactively, for a valid Alternate MOTLoad boot image; anticipated to be an
upgrade of alternate MOTLoad firmware. If found, the image is executed. A return
to the boot block code is not anticipated.
 Execute the recovery image of the firmware in the boot block if no valid USER or
alternate MOTLoad image is found
During startup, interactive mode may be entered by either setting the Safe Start
jumper/switch or by sending an <ESC> to the console serial port within five seconds of the
board reset. During interactive mode, the user has the option to display locations at which
valid boot images were discovered, specify which discovered image is to be executed, or
specify that the recovery image in the boot block of the active flash bank is to be executed.
