3. Installing the trace and debug tool on your target board[edit source]
3.1. Using the STM32MPU Embedded Software distribution[edit source]
ifconfig is installed by default and ready to be used with all STM32MPU Embedded Software Packages.
It comes with the busybox:
which ifconfig | xargs ls -la /sbin/ifconfig -> /bin/busybox.nosuid
3.2. Using the STM32MPU Embedded Software distribution for Android™[edit source]
4. Getting started[edit source]
Follow the sequence described below to get started with the ifconfig tool.
4.1. List the available network interfaces[edit source]
ifconfig
eth0 Link encap:Ethernet HWaddr 00:80:E1:42:43:65
inet addr:10.48.1.144 Bcast:10.48.3.255 Mask:255.255.252.0

RX bytes:13454 (13.1 KiB) TX bytes:13454 (13.1 KiB)
4.2. Disable the network interface[edit source]
- For example, proceed as follows for eth0
ifconfig eth0 down
4.3. Enable the network interface if it is not already available[edit source]
- For example, proceed as follows for eth0
ifconfig eth0 up
4.4. Assign a given IP address to a network interface[edit source]
- Proceed as follows to assign 10.48.1.324 address to eth0
ifconfig eth0 10.48.1.324
5. To go further[edit source]
Refer to the man page[1] for more details on command options.
