This directory 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-openthread> $ ./script/bootstrap
$ cd <path-to-openthread> $ ./bootstrap $ make -f examples/Makefile-kw41z
After a successful build, the
elf files are found in
<path-to-openthread>/output/kw41z/bin. You can convert them to
bin files using
$ 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.
Prepare two boards with the flashed
CLI Example (as shown above).
The CLI example uses UART connection. To view raw UART output, start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings:
Open a terminal connection on the first board and start a new Thread network.
> dataset init new Done > dataset Active Timestamp: 1 Channel: 13 Channel Mask: 07fff800 Ext PAN ID: d63e8e3e495ebbc3 Mesh Local Prefix: fd3d:b50b:f96d:722d/64 Master Key: dfd34f0f05cad978ec4e32b0413038ff Network Name: OpenThread-8f28 PAN ID: 0x8f28 PSKc: c23a76e98f1a6483639b1ac1271e2e27 Security Policy: 0, onrcb Done > dataset commit active Done > ifconfig up Done > thread start Done
After a couple of seconds the node will become a Leader of the network.
> state leader
Open a terminal connection on the second board and attach a node to the network.
> dataset masterkey dfd34f0f05cad978ec4e32b0413038ff Done > dataset commit active Done > ifconfig up Done > thread start Done
After a couple of seconds the second node will attach and become a Child.
> state child
List all IPv6 addresses of the first board.
> ipaddr fd3d:b50b:f96d:722d:0:ff:fe00:fc00 fd3d:b50b:f96d:722d:0:ff:fe00:c00 fd3d:b50b:f96d:722d:7a73:bff6:9093:9117 fe80:0:0:0:6c41:9001:f3d6:4148 Done
Choose one of them and send an ICMPv6 ping from the second board.
> ping fd3d:b50b:f96d:722d:7a73:bff6:9093:9117 16 bytes from fd3d:b50b:f96d:722d:558:f56b:d688:799: icmp_seq=1 hlim=64 time=24ms
