Introduction Some time ago, Freescale introduced its which is a cheap (about $13) platform for their Kinetis L Series microcontrollers (which are built on ARM Cortex M0+ processor). The platform includes four boards with the same footprint but different MCUs. Of those four board the FRDM-KL25Z is probably the most popular and is also supported by the community. In this tutorial I will describe how to create and run your first program on the FRDM-KL25Z board using CodeWarrior, which is the board's 'native' IDE provided by Freescale itself. Note that there are other (and easier-to-use) options for developing your programs for this board, such as. These options have their own documentation, so if you decide to use them, I don't have much to offer you in this tutorial.

If you, however, prefer using the CodeWarrior IDE, I hope to make your first steps easier. Background One nice feature of the FRDM-KL25Z, appealing especially to the DIY community, is that it is possible to attach expansion boards (so called shields) for to this board.

Given the wide range of such 'shields' available elsewhere, it makes it very easy to connect the FRDM-KL25Z with interesting pieces of hardware. The downside is, that out-of-the-box it is very hard to start writing your own programs for this board - the documentation is not easy to find and not very good. Or maybe I am not good in searching.

But I imagine there would be a step-by-step tutorial on writing some 'hello world', blinking LED program. The manufacturers website promises such tutorial as a part of a sample code package for the board, but all I found in this package was small readme.txt which left me with many questions unanswered. It is a pity, because the sample code package contains some nice drivers which can make your programming much easier - if you take the time to find out how it all works.

And it does take time to find this by trial and error. So after going through this process I decided to write a tutorial to make things easier for those who also want to develop their own program for this board. The fact that the FRDM-KL25Z board is 'Arduino compatible' may give some people the idea that this board could be used as a more powerful and yet cheaper alternative to the standard Arduino boards. However, it should be noted that the compatibility is only at the hardware level - you can connect expansion boards (shield) designed for Arduino to the FRDM-KL25Z - but there is no software compatibility. You cannot use the Arduino 'language' or libraries with this board. The closest you can get to the Arduino's ease-of-programming is probably the platform, but its cloud principle with online compiler is hard to swallow for some people (including me). If you prefer classical IDE and want to go the easy way, try.

It is free and I liked the IDE when I tried it about a year ago. As I saw recently, it also has some libraries for the FRDM-KL25Z in the form of 'components'. I am a bit suspicious about GUI interfaces for adding components into your programs, but I haven't tried it yet. If you are brave enough (or perhaps serious enough about your embedded developer career) to deal with professional IDE and plain C language, Freescale's CodeWarrior is the 'native' option. This is not the easy way, but if you do choose it, I hope this tutorial will make the start easier.

The hardware I will not describe the hardware here in detail as it is described elsewhere - for example,. Just some important notes:. The board actually contains two microcontrollers - one works as a programming interface (OpenSDA MCU) and the second one is the one into which you load your application (target MCU). In other words, it combines the target MCU and programming and debugging interface in one board. The MCU for your applications is Kinetis L series, MKL25Z128. At least on my board, which is named FRDM-KL25Z.

There are other variants of the board with different MCUs. There are two USB connectors on the board; the one named OpenSDA is the one we will use for programming and debugging. The one named KL25Z is for user applications with USB. The programming and debugging is done through interface. This interface also works as a mass storage device (MSD) so when you connect the board to your computer, it will appear as a disk drive (named FRDM-KL25Z). And if you copy your program's binary (.srec file) into this disk, it will load the program into the target MCU. So you can actually load programs to the board just by copying them in any file manager!.

The program (firmware) running in the OpenSDA MCU is called OpenSDA application. If you are used to traditional MCU programming using a separate programmer device, you could say that the OpenSDA application is the programmer's firmware. There are (were) several OpenSDA applications, for example, one for flashing and debugging your program, one for virtual serial port and one for the MSD programming described above. Currently, all these three useful applications are merged into one. So you do not have to switch the OpenSDA applications depending on what you want to do. You can do everything with just one application.

If you do need to change or update the OpenSDA application (which equals to updating your programmer's firmware), this is done by going into bootloader mode (hold down the reset button while plugging the USB cable into your computer) and copying the new OpenSDA application to the mass storage drive (named BOOTLOADER in this case).
