This repo contains example platform drivers for the NXP(Freescale) Kinetis MKW41Z512 based on FRDM-KW41Z hardware platform.

The example platform drivers are intended to present the minimal code necessary to support OpenThread. As a result, the example platform drivers do not necessarily highlight the platform's full capabilities.

Download and install the GNU toolchain for ARM Cortex-M.

In a Bash terminal, follow these instructions to install the GNU toolchain and other dependencies.

$ cd <path-to-ot-kw41z>
$ ./script/bootstrap

In a Bash terminal, follow these instructions to build the kw41z examples.

$ cd <path-to-ot-kw41z>
$ ./script/build

If the build completed successfully, the elf files may be found in <path-to-ot-kw41z>/build/bin/. You can convert them to bin files using arm-none-eabi-objcopy:

$ arm-none-eabi-objcopy -O binary ot-cli-ftd ot-cli-ftd.bin

Compiled binaries may be flashed onto the MKW41Z512 using drag-and-drop into the board's MSD Bootloader or the NXP(Freescale) Test Tool or JTAG interface. The NXP(Freescale) Test Tool provides a convenient method for flashing a MKW41Z512 via the J-Link.

1. The CLI example uses a UART connection (serial port settings: 115200 8-N-1).
2. Type help for list of commands.
3. See OpenThread CLI Reference README.md to learn more.
