This message halts the 9-second countdown and the boot process. It causes the bootloader to
immediately send back an
Erase NBB Flash Acknowledge
UDP message. Next the bootloader
erases the contents of the larger bank of flash (the Non-Boot Bank or NBB). After the GES
completes the erase, the bootloader sends an
Erase NBB Flash Complete
UDP message. This
last message indicates to the loader that it may begin sending
Program NBB Data
UDP
messages containing the contents of the new GES Application to program into the NBB flash.

seconds.
