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
