C++ example for Cortex-M4 using gnu g++ compiler?

Hi David,

I assume you imported the uVision Simulator version of the Blinky example. This is configured by default for Cortex-M3. If you wish to change it for Cortex-M4, open the .rteconfig file. and go to the Device Tab, and click Change, and select ARMCM4(_FP) (if floating point desired). The example I attached yesterday may be easier to consume.

To run, select Fiile > New > Model Connection, and give it a meaningful name. Also recommend associating with the project for ease of file management. In next pane, select MPS2_Cortex-M4 from the FVPs (Fixed Virtual Platforms) installed with Arm DS. Finally, in the Files tab, navigate to the .axf built in the Workspace, and in Debugger tab, Debug from main (or entry point), Click debug, and the model will launch and load the code (to repeat, you will be able to just double click on this connection in the Debug Connections pane).

Hi Ronan,

Thanks, I have successfully built the Blinky example and created a debug connection for it. Please will you remind me what I need to do to see the printf output in the Target Console?

If you have time, I would be grateful for steps to add C++ source file.

Best regards

David

To add a C++ file, this is not straight forward in this case. I don't think there is an option to change a C project to a C/C++ project. If you are just adding a single C++ source file, you can right click on that file, and in Properties > Tool Chain Editor, select the C++ compiler. You then need to go to Settings and enter compatible build options for the C builds. This will only apply to this source file, so isn't very scalable :(

The easiest solution (sorry) is to create a New > Project > C/C++ > C++ Project > CMSIS C/C++ Project, and then copy over the Blinky.c source file. You will need to setup the generated .rteconfig file the same way as it was for the previous project, but that is fairly straight forward from the GUI (and is likely do-once operation).
