3.11 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.
