3.2 Remote Update
The PM-L supports OTA field upgrades of the resident application. An over the air TFTP
(Trivial File Transfer Protocol) connection is made over an IP connection. A replacement file
is then transferred from a server to the PM-L and that file replaces the previous application
image.
3.3 Auto Execute
The Auto Execute Utility copies the contents of file system.exf into system executable RAM
and executes it from there. This file is the factory default application. Another file named
custom.exf can be loaded into the file system.
Auto Execute will look first for a file named update.exf and load and execute that in place of
custom.exf if it exists. If update.exf executes successfully, the previous copy of custom.exf is
deleted from the file system and update.exf is renamed to custom.exf.
