A template to generate Hello World semihosted application running on QEMU

Generate simple bare-metal Hello World applications that run on QEMU (Arm Cortex-M, Arm Cortex-A 32/64 and RISC-V 32/64 devices).

The project is hosted on GitHub as micro-os-plus/hello-world-qemu-template-xpack, and is also available from npmjs.com as @micro-os-plus/hello-world-qemu-template. As the name implies, is part of the µOS++ project.

Features

This project generates multiple variants of the classical application that prints the Hello World message on standard output.

Both C and C++ are supported, with CMake and meson as build system generators.

The targeted devices are:

  • Arm Cortex-M0 (ARMv6-M)
  • Arm Cortex-M7F (ARMv7-M FP)
  • Arm Cortex-A15 (AArch32)
  • Arm Cortex-A72 (AArch64 FP)
  • RISC-V RV32IMAC (32-bit)
  • RISC-V RV64IMAFDC (64-bit FP)

The template can be instantiated in a terminal, but the intended use was to be integrated into the VS Code xPack Build extension and Eclipse Embedded CDT, to generate new projects.

Prerequisites

A recent xpm, which is a portable Node.js command line application.

npm install --global xpm@latest

If installing over a previous version fails, uninstall first:

npm uninstall --global xpm
npm install --global xpm@latest

For details please follow the instructions in the xPack install page.

User info

Template instantiation via xpm init

Instantiating the template can be done via the xpm init --template command, pointing to this xPack.

This command must be invoked in an empty folder, where the project will be generated.

There are two modes, interactive and scriptable (non interactive).

Interactive mode

Starting the tool without defining the target will select the interactive mode and the user can manually enter each choice.

% mkdir -p my-project && cd my-project

Scriptable mode

When used in non-interactive environments, it is possible to pass all required data on the command line. The only mandatory property is target, all other have defaults.

% mkdir -p my-project && cd my-project
% xpm init --template @micro-os-plus/hello-world-qemu-template@latest --property target=cortex-m7f

Satisfy dependencies

The next step is to install all dependencies, either source packages or binary tools.

This can be automated by issuing the xpm install command in the project folder:

Toolchains

The generated projects use the xPack GNU Compiler Collection toolchains.

Windows specifics

On Windows, the VS Code IntelliSense logic does not properly identify the toolchain when installed via npm/xpm (#28); thus the need for CMake and meson to use the explicit program extensions (like arm-none-eabi-gcc.cmd).

Known problems

  • none
