2.2 Installing Software for the FRDM-KL25Z
2.3 Jump Start Your Design with the Kinetis SDK
Want to learn about SDK
The Kinetis Software Development Kit (SDK) is complimentary and includes full source code under a permissive open-source license for all hardware abstraction and peripheral driver software.
Click below to download the SDK Release appropriate for your computer's operating system.
2.4 Install Your Toolchain
NXP offers a complimentary toolchain called MCUXpresso IDE.

Want to use a different toolchain?
If you prefer using a different toolchain, the Kinetis SDK includes support for other tools such as
IAR, Keil and command-line GCC.
2.5 PC Configuration
Many of the example applications output data over the MCU UART so you’ll want to make sure that the driver for the board’s virtual COM port is installed. It should install automatically when you plug the board into your PC. If the driver does not automatically install, click
here to download the installer.
With the serial port driver installed, run your favorite terminal application to view the serial output from the MCU's UART. Configure the terminal to 115200 baud rate, 8 data bits, no parity and 1 stop bit. To determine the port number of the FRDM-K64F's virtual COM port, open the device manager and look under the "Ports" group.
