2. NetBootLoader Operation
The basic function of the NetBootLoader is to configure the CPU module for operation and then
to load and start an operating system. In addition, it provides functionality for controlling the op-
eration of the NetBootLoader itself, for programming images or data to the NBL-Flash(es) and
NAND Flash, remote operation access, accessing TFTP or FTP servers, and acquiring Motor-
ola S-Record images.
2.1 NetBootLoader Control
The NetBootLoader provides various functions for controlling the operation of the
NetBootLoader itself as well as the setting of operational parameters. The following table
