OpenThread on NXP(Freescale) Kinetis MKW41Z512 Example

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.

Toolchain

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

Build Examples

$ 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:

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

Flash Binaries

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.

Running the example

1. Prepare two boards with the flashed CLI Example (as shown above).

2. 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:

   • Baud rate: 115200
   • 8 data bits
   • 1 stop bit
   • No parity
   • No flow control

3. 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
   

4. After a couple of seconds the node will become a Leader of the network.

   > state
   leader
   

5. 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
   

6. After a couple of seconds the second node will attach and become a Child.

   > state
   child
   

7. 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
   

8. 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
