Getting started with ARM Cortex M4 - running your first project

As with every other new language/hardware, we start off with the hello world project. To do that, first open Kinetis Design Studio(KDS). Select File -> Import. In the Import wizard, select "Project of projects" -> Existing projects sets and click next. 

Browse the C drive to find the frdmk22f folder in the Freescale installation path. Find the hello world folder in the demo apps directory and open the kds folder. My installation path is as follows. "C:\Freescale\KSDK_1.2.0\examples\frdmk22f\demo_apps\hello_world\kds". Select the file named "hello_world.wsd" and import it into the project explorer of KDS. 

Now two different projects appear in the project explorer. Select the "kdsk_platform_lib_K22F51212", right click on it and select "Build project". The project should build successfully. If there is any problem, right click and select "Clean project" and then "Build project".

Now, right click on the "kdsk_platform_lib_K22F51212" project and select Delete. Do not check the "Delete project contents on disk" option. Now we have all our platform libraries built and ready. Next, right click on the "hello_world_frdmk22f" project and select "Clean project" and then "Build project". Now, the project should successfully build.

Next, we'll need to start a terminal window. I prefer putty. Figure out the com port of your development board to use in putty. Use 115200 kbps as the baud rate. Now, debug the project in KDS using GDB PEMicro debugger (Installing the debugger in KDS was already done in the previous post). Once in the debug perspective, press resume button. You should be able to see the output "Hello world!" in the terminal.

Cheers,

Vijay.
