Bug fixes

  • [#62] in certain conditions, like half-word or byte accesses, clearing the STM32F GPIO pins was not effective; the problem was identified as an erroneous persistence of the BRR/BSRR registers, and was fixed by disabling the persistence.

Known problems

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


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

Build notes

The GNU/Linux binaries were built on two CentOS 6 Docker images (32/64-bit), and run on any distribution based on CentOS 6 or later.

The Windows binaries were built with mingw-w64, and run on any reasonably recent i686 and x86_64 Windows machines.

Easy install

QEMU is also available as an xPack and can be conveniently installed with xpm:

$ xpm install --global @gnu-mcu-eclipse/qemu@2.8.0-4.1

To install the latest version available, use:

$ xpm install --global @gnu-mcu-eclipse/qemu

Note: The method to select the path based on the xPack version was already added to the Eclipse plug-in, but for now is only available in the version published on the test site (

Manual install

Instructions on how to install the binaries are available in the How to install the QEMU binaries? page.
