Developer & maintainer pages:


QEMU is the long-standing open-source cross-platform emulator. It is mature, it provides a good framework for emulation, it implements a GDB server, it provides support for semihosting, and although it does not intend to accurately simulate processor time behaviour, it does keep a quite accurate track of time when emulating timer interrupts, so it can also be used to emulate applications using RTOS-es.


xPack QEMU RISC-V is a cross-platform binary distribution of the public open-source QEMU project.


The main benefits of using the xPack QEMU RISC-V are:

  • a convenient, uniform and portable install/uninstall/upgrade procedure, the same procedure is used for all major platforms (Intel Windows 64-bit, Intel GNU/Linux 64-bit, Arm GNU/Linux 64/32-bit, Intel macOS 64-bit, Apple Silicon macOS 64-bit)
  • a better integration with development environments like Eclipse Embedded CDT; users can run the Hello World projects generated by the Eclipse templates immediately, without any specific hardware, neither development board nor JTAG programmer; all debugging features, like single stepping, inspecting variables, registers, etc. are supported
  • a convenient integration with Continuous Integration environments, like GitHub Actions; the emulator provides a very convenient platform for running unit tests, fully supporting the semihosting features required for this.

All binaries are self-contained, they include all required libraries, and can be installed in any location.

Compatibility & peripherals

The xPack QEMU RISC-V is fully compatible with the original qemu-system-riscv32 and qemu-system-riscv64.

xPack QEMU RISC-V is generally intended for running tests, mainly unit tests.

Semihosting and ITM

The recommended method to display messages from the target is via semihosting.


The official QEMU documentation is available online.


The details of installing the xPack QEMU RISC-V on various platforms are presented in a dedicated install page.


The recommended method to test QEMU is using the new Eclipse QEMU RISC-V Debugging plug-in; create a test project using the Hello World project template.


For the various support options, please read the separate support page.

Change log

The release and change log is available in the repository CHANGELOG.md file.

Build details
