It is a good idea to use the default workspace, you may want to note where it is located. If you always want to use the same workspace, you may select the Use this as the default This is usually a good idea once you've used Eclipse for a while.
Finally Eclipse starts up with the welcome screen:. And if you select the "Go to the workbench" the backward arrow on the right, then you are inside Eclipse. If you have downloaded a different package, there are additional tools needed to start programming. This is only required if you did not download the CDT version as described above.

In the section "builder", de-select "use default build command" and for "Build command" enter "gmake". Once you are in Eclipse, you are given an empty workspace. You now have to start a new project. On the next screen, you have to give your project a name. In this case, it will be "HelloWorld", however, you may use any name you like.
Also, you have to select a toolchain. In the last setting you can chose output formats, it is always good to have a release and a debug configuration. Click "Finish". This is a good idea, so say yes. You have a project now, and it does contain some sample code!
You will immediately get an editor window for your project. Eclipse will also auto-build your project every time you save.

It is possible to just use mingw-make and no MSYS at all, however, mingw-make has some limitations. Eclipse CDT managed makefiles may or may not work with it. If you are on windows, and neither of them worked, install MinGW and set your path environment variable.

The compiler says this:. Answer: Your program may still be running. Try stopping it by using the small red square on the console window the one for your program.
Another way is switching to the "Debug" perspective, selecting your running program, and stopping it there also the small red square. Unfortunately gdb is not included in the current 4. See GDB optional! Make sure you are using the make programs provided by MinGW. If your output in the console shows something like:. You have several choices:. This problem happens on Windows when you moved Eclipse out of its directory instead of creating a shortcut.

Simply installing the CMSIS Packs manger is not enough, you need to update the list of available packs and to install the desired ones. Before proceeding to create your own projects, it is highly recommended to create a test blinky project, and to run it via the QEMU emulator. This validates that the plug-ins are installed properly, that the toolchain is available, and the debug plug-ins are available and configured properly.
