5.3.3.2 TFTP/FTP Server Access
The NetBootLoader provides various functions for interfacing with either a TFTP or FTP server.
The TFTP server access is a simple method of acquiring a userimage from a remote source.
Its primary use is to download a single executable image from a given source. For example,
once an image has been created it would be possible to store it at a remote location where it
then would be available for remote booting of an AM4100 via an Ethernet port.
The TFTP/FTP server commands provide various functions consistent with interfacing with
such a server.
The following table provides an overview of available TFTP/FTP server functions.
