If you don't like this, you can set a breakpoint on the return 0 statement in main or replace it with a while (1) instruction, so the program will not return. We are running the program bare-metal, remember. This is caused by the fact that the program returns with a return 0 statement but there is nothing (no operating system) to return to. When you run the program it ends with a message that the source for svc.h can not be found. You can see the output and enter the input in the Target Console window, as shown here. Open the option DS-5 Debugger, select calendar_Armv8-A_GCC-FM, as shown below and click Debug and Yes.Right click on the project name in the Project Explorer and choose Debug As, Debug Configurations.Click on the Build button or right click on the project name in the Project Explorer and choose Build Project.Select GCC 7.5.0 as Current toolchain.Uncheck the Display compatible toolchains only option.Right click on the project name calendar_Armv8-A_GCC in the Project Explorer and choose Properties.Check the calendar_Armv8-A_GCC example and the Copy Projects into Workspace option, as shown below.Select the directory C:\Bare-metal_examples_Armv8\.→ General → Existing Projects into WorkspaceWindow. You can run the calendar_Armv8-A_GCC example in DS-5 as follows: For example into the directory C:\Bare-metal_examples_Armv8\. Unzip the file Bare-metal_examples_Armv8.zip which under Windows can be found in C:\Program Files\DS-5 CE v5.29.1\examples\.

This toolchain can be downloaded from the Linaro website. You will also have to download a proper toolchain which includes an ARMv8 simulator. The installation does not need any further explanation. Which can be downloaded from ARM or here. You will use the free Community Edition of ARM's Integrated Development Environment called DS-5. LEGv8 is a simple version of ARMv8 defined and used in the book Computer Organization and Design - The Hardware/Software Interface ARM Edition by David A.
