on how to download the respective CLI description file.
Step Command Purpose
1
optional
RedBoot> ip_address - l local_ip_address
[ / mask_len ]
Sets the IP address and subnet mask of the
Ethernet interface 0/0 which shall be used to
receive the new application image.
mask_len is the length of the network address
(or the number of 1’s within the subnet
mask).

RedBoot> ping -h tftp-server_ip_address Tests the connectivity to the TFTP server.
4 RedBoot> load -r -v -h host -b base_ad-
dress file_name
Downloads an application image into the vol-
atile memory (RAM) from where the Smart-
Node could directly execute it.
host : IP address of the TFTP server
base_address : memory location where to
store the application image. Use the default
address 0x1800100
file_name : path and name of the file on the
TFTP server. Note: use the image file that
contains the whole application, not the image

Note
With the Bootloader, only the Ethernet interface 0/0 is available. The Boot-
loader applies the IP address, subnet mask, and default gateway that were last
configured by the Bootloader itself or by another application (e.g. Smart-
Ware). If an application configured the Ethernet interface 0/0 to use DHCP,
the Bootloader will also use DHCP to learn the interface configuration. It
can receive and apply the IP address, subnet mask, default gateway, and
default (TFTP) server (transmitted as basic DHCP information ‘Next server
IP address’).
