RISC-V 32 emulator with not a lot of features.

nrv32emu - RISCV emulator

This project contains an emulator that currently only supports the RISC-V 32-bit architecture. I wrote this as a learning project for myself, so it is not as performant as it could be.

My goal is to get linux to boot and have a usable shell. I have not reached this completely yet. The emulator can run the bootloader and starts booting linux but fails before reaching userspace. Currently I mostly test the project with Zephyr RTOS.

A lot of the ideas, structure and implementation details are taken from Fabrice Bellards TinyEMU project.

Usage

To run, simply use cargo run. This will load the zephyr image into RAM and start executing.
