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]
ifconfig is installed by default and ready to be used with all STM32MPU Embedded Software Packages for Android™.
It comes with the toybox:
which ifconfig | xargs ls -la /system/bin/ifconfig -> toybox
4. Getting started[edit source]
Follow the sequence described below to get started with the ifconfig tool.

4.2. Disable the network interface[edit source]
- For example, proceed as follows for end0
ifconfig end0 down
4.3. Enable the network interface if it is not already available[edit source]
- For example, proceed as follows for end0
ifconfig end0 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 end0
ifconfig end0 10.48.1.324
