KW41Z board is most suitable for the open source project OpenThread opening post [Copy link]

I haven't been to the forum for a long time. I almost forgot which administrator gave me this board. It has been gathering dust for almost a year. It's a pity for such a good board to gather dust. I'll just start it and continue to update it when I have time. The openthread project is an open source project initiated by nest lab. It belongs to the protocol stack of 6LoWPAN. There are always opportunities in the IoT era. There is no reason to refuse to learn such a powerful open source project. It has been promoted in the forum before, but it seems that no forum friends have started it. I processed the pins on the board first. I didn't like the original design, so I added four screws to fix it. I suggest you take a good look at the schematic before starting. This board is actually designed with so many jumpers. It is mainly designed to maximize the use of the evaluation board. It is mainly related to power supply and low power consumption. It is convenient for testing and experimenting. The only drawback is that it doesn't look so elegant. It's barely passable. It's still very convenient to use. It's basically enough to bring openSDA and serial port. It's very convenient for MAC to copy the firmware directly through the virtual U disk. Ok, let's get started. Openthread is already very complete. Just run the script and it will work. You don't need to install a cross compiler yourself. Refer to the link below. https://github.com/openthread/openthread/tree/master/examples/platforms/kw41z Very concise. The firmware is compiled in just three steps. I have to admit that makefile is flexible. Of course, the internal resources of this chip are still sufficient. 128K RAM is very sufficient. Screenshot of the compilation process. The speed is very fast, much faster than IAR. After compiling, just drag the bin file to the virtual USB drive and power it on again. Then use minicom to connect to the serial port. You can use the help command to view the supported commands. There are many complicated commands. At present, the main task is to build the environment, and then analyze it bit by bit. Overall, I feel that this is a very good project and it is very active. If you are interested, please follow the board.

Yes, my board is also gathering dust. I’ll tinker with it when I have some free time.

After I compiled the firmware and configured the network, when I queried the status later, the printed data was garbled. Have you encountered such a situation?
