Hello

Hello project

This project prints "Hello World" and a counter value via the UART output. It is configured for Arm Virtual Hardware, but other target hardware that provides a CMSIS Driver:USART can be easily added.

Prerequisites

Tools

• CMSIS-Toolbox 2.0.0 or higher
• Keil MDK 5.37
  • Arm Compiler 6.18 (part of MDK, Eval Version sufficient for compilation)
  • Arm Virtual Hardware for Corstone-300 v11.18.1 (requires MDK - Professional)

Note: later versions will also compiler with GCC.

Packs

• Required packs are listed in the file Hello.csolution.yml and Hello.cproject.yml

Project Structure

The project is generated using the CMSIS-Toolbox and is defined in csolution format:

• Hello.csolution.yml lists the required packs and defines the hardware target and build-types (along with the compiler).
• Hello.cproject.yml defines the source files and the software components.

Generated Project

> cbuild Hello.csolution.yml --packs

Note: During the build process required packs may be downloaded.

Execute Project

The project is configured for execution on Arm Virtual Hardware which removes the requirement for a physical hardware board.

• When using MDK-Professional, you may execute it with the command:

For debug type

> C:/Keil_v5/ARM/VHT/VHT_Corstone_SSE-300_Ethos-U55 -f vht-config.txt -a ./out/Debug/Hello.axf

For release type

> C:/Keil_v5/ARM/VHT/VHT_Corstone_SSE-300_Ethos-U55 -f vht-config.txt -a ./out/Release/Hello.axf

• Keil Studio Cloud integrates also the Arm Virtual Hardware VHT_Corstone_SSE-300_Ethos-U55 model. The steps to use the example are:
  • Start Keil Studio Cloud and login to the system using your account.
  • Use File - Clone and enter the URL: (https://github.com/Open-CMSIS-Pack/csolution-examples). Add
  • Select from the drop-down Target hardware: Corstone SSE-300 (Cortex-M55, Ethos-U55)
  • Click Run project which executes the project build step and then starts running on Arm Virtual Hardware.
