load {file} [-v] [-b location] [-r] [-m {[xmodem]|[ymodem]|[tftp]} ] [-h

DESCRIPTION
The load command is used to download data into the target system. Data can be loaded via a
network connection, using either the TFTP protocol, or the console serial connection using the
X/Y modem protocol. Files may also be loaded directly from local filesystems on disk.
Files to be downloaded may either be executable images in SREC (see “SREC” page -19) for-
mat or raw data.
Arguments
file
The name of the file on the TFTP server.
-v
Display a small spinner (indicator) while the download is in progress. This is just for feed-
back, especially during long loads. Note that the option has no effect when using a serial
download method since it would interfere with the protocol.
-b
Specify the location in memory to which the file should be loaded. Executable images nor-
mally load at the location to which the file was linked. This option allows the file to be loaded
to a specific memory location, possibly overriding any assumed location.
-r
Download raw data. Normally, the load command is used to load executable images into
memory. This option allows for raw data to be loaded. If this option is given,
-b
will also be
required.
-m
The -m option is used to select the download method. The choices are:
xmodem, ymodem, zmodem serial download using standard protocols over the console
serial port. When using this method, the file parameter is not required.
tftp
Network based download using the TFTP protocol.
-h
Used explicitly to name a host computer to contact for the download data. This works in
TFTP mode only.
