Network speed and duplex settings
The “ethtool” utility used to query and change settings such as speed, auto- negotiation and checksum offload on
many network devices, especially Ethernet devices. This section explains how to set the Ethernet speed to
10/100/1000 Mbps or half/full duplex in the iW-RainboW-G15M platform.
Turn off Auto-Negotiate feature using the following command.
root@iWave-G15~$ethtool -s eth0 autoneg off
Execute the below command to set the desired speed/duplex in the ethernet.
root@iWave-G15~$ethtool -s eth0 speed [SPEED] duplex [DUPLEX]
Example
root@iWave-G15~$ethtool -s eth0 speed 100 duplex half
root@iWave-G15~$ethtool -s eth0 speed 10 duplex full
Execute the below command to check the current Ethernet network speed and duplex settings.
root@iWave-G15~$ethtool eth0
Note: The Max. Speed 1000Mbps can be set only if the iW-RainboW-G15M platform is connected in the 1000Mbps
network.
File transfer using TFTP server
To receive any file from TFTP server to iW-RainboW-G15M-Q7 platform, execute the below command
root@iWave-G15~$tftp -g <server_ip> -r <file_name>
To transmit any file from iW-RainboW-G15M-Q7 platform to TFTP server (host PC), execute the below
command
root@iWave-G15~$tftp -p <server_ip> -l <file_name>
Folder mount from NFS
To mount any folder from NFS server (Host PC) to iW-RainboW-G15M-Q7 platform, execute the below
command
