Install License Key

Xtensa development tools use FLEXlm for license management. FLEXlm licensing is required for tools such as the Xtensa Xplorer IDE, Xtensa C and C++ compiler, and Instruction Set Simulator (ISS).

Currently RT600 supports node-locked license for Xtensa tools. A node-locked license permits tools to run on a specific computer, tied to the MAC address of the primary network interface permanently attached to the machine.

Identify PC MAC Address

To generate the correct license file, you should first identify the appropriate MAC for the computer you plan to run Xtensa tools on. Remove ‘-‘ or ‘:’ symbols in the MAC address.

Windows:

Linux:

Note: For Linux: MAC address must be associated with eth0 interface. If not, FLEXlm cannot perform the license checkout, compilation, or simulation of code is not possible. If the host has the MAC address associated with another interface, for example em1, the following approach may be used.

# Add udev rule for naming interface
$ sudo vim /etc/udev/rules.d/70-persistent-net.rules
# udev rule (replace ‘XX’ with the MAC address of your PC):
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="XX:XX:XX:XX:XX:XX", NAME="eth0"
# Change "em1" to "eth0" in your interfaces file.
$ sudo vim /etc/network/interfaces
# Restart udev or reboot machine
$ sudo reboot

Alternatively, you can use the approach recommended by your IT team to rename the interface to eth0.
