QEMU Emulation for RISCV32E

Board Overview

Vendor:

QEMU, a generic and open source machine emulator and virtualizer

Architecture:

riscv

SoC:

qemu_virt_riscv32e

Overview

The RISCV32E QEMU board configuration is used to emulate the RISCV32 (RV32E) architecture.

Programming and Debugging

Applications for the qemu_riscv32e board configuration can be built and run in the usual way for emulated boards (see Building an Application and Run an Application for more details).

Flashing

While this board is emulated and you can’t “flash” it, you can use this configuration to run basic Zephyr applications and kernel tests in the QEMU emulated environment. For example, with the Basic Synchronization sample:

# From the root of the zephyr repository
west build -b qemu_riscv32e samples/synchronization
west build -t run

This will build an image with the synchronization sample app, boot it using QEMU, and display the following console output:

*** Booting Zephyr OS build v3.1.0-rc1-59-g0d66cc1f6645  ***
