Zephyr
Notes on running Zephyr demos on emulated STM32 boards with the xPack QEMU Arm build. See also QEMU.
Linux
Install the toolchain and QEMU with xPacks:
npm install --global xpm@latest
cd my-project
xpm init
xpm install @xpack-dev-tools/arm-none-eabi-gcc@latest --verbose
xpm install @xpack-dev-tools/qemu-arm@latest --verbose
~/.local/xPacks/@xpack-dev-tools/arm-none-eabi-gcc/12.2.1-1.2.1/.content/bin/arm-none-eabi-gcc --version
~/.local/xPacks/@xpack-dev-tools/qemu-arm/7.2.0-1.1/.content/bin/qemu-system-gnuarmeclipse --version
In Eclipse, open Marketplace, search for mcu, and install Eclipse Embedded C/C++. The QEMU executable lives at:
/home/dev/.local/xPacks/@xpack-dev-tools/qemu-arm/7.2.0-1.1/.content/bin/
Results with the blinky demo (LED visible on the emulator screen):
| Board | Device | Emulator LED |
|---|---|---|
| STM32F4-Discovery | STM32F407VG | Works |
| STM32F429I-Discovery | STM32F429ZI | Does not work |

Windows
Run from the Command Prompt. With the blinky demo, the LED does not appear on the emulator screen for NUCLEO-F103RB.
