Version 2.8.0-8 is a maintenance release, to fix a bug affecting STM32F1 GPIOs.


The binary files are available from GitHub releases.


The full details of installing the xPack QEMU Arm on various platforms are presented in the separate Install page.

Easy install

The easiest way to install QEMU Arm is with xpm by using the binary xPack, available as @xpack-dev-tools/qemu-arm from the registry.

To install the latest version available, use:

xpm install --global @xpack-dev-tools/qemu-arm@latest --verbose

To install this specific version, use:

xpm install --global @xpack-dev-tools/qemu-arm@2.8.0-8.1


xPack QEMU Arm currently is based on the official QEMU, with major changes.

The current version is based on:

  • QEMU version 2.8.0, commit 0737f32 from Dec 20th, 2016


Compared to the master qemu-system-arm, the changes are major, all application class Arm devices were removed and replaced by several Cortex-M devices.

The supported boards are:

xPack 64-bit QEMU v2.8.0 (qemu-system-gnuarmeclipse).

  generic              Generic Cortex-M board; use -mcu to define the device

Supported MCUs:

Warning: support for hardware floating point on Cortex-M4 devices is not available yet.

Bug fixes

  • [#1] due to an unfortunate copy/paste in a previous patch, some references to F4 were added to the F1 GPIO code, crashing QEMU for F1 targets; fixed;
  • [#2] due an error in a previous patch enabling custom RAM sizes, the actual device RAM size was overridden by 128 and small boards had more memory than real; fixed.

Known problems

  • Ctrl-C does not interrupt the execution if the --nographic option is used.


The original documentation is available in the share/doc folder.

Supported platforms

Binaries for Windows, macOS and GNU/Linux are provided.

The binaries were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.

  • GNU/Linux: all binaries were built with GCC 7.4, running in a CentOS 6 Docker container
  • Windows: all binaries were built with mingw-w64 GCC 7.4, running in a CentOS 6 Docker container
  • macOS: most binaries were built with GCC 7.4, running in a separate folder on macOS 10.10.5; GDB cannot be compiled with GCC, so Apple clang was used.


The binaries were testes on Windows 10 Pro 32/64-bit, Ubuntu 18 LTS 64-bit, Xubuntu 18 LTS 32-bit and macOS 10.14.

The tests consist in running a simple blinky application on the graphically emulated STM32F4DISCOVERY board. The binaries were those generated by simple Eclipse projects available in the xPack GNU Arm Embedded GCC project.
