🐧 ESP32 Running Linux via RISC-V Emulator

This project implements a RISC-V emulator on the ESP32 microcontroller, capable of running a minimal Linux environment.

📄 Overview

This project enables the execution of a lightweight Linux environment on the ESP32 by emulating RISC-V instructions. It leverages the ESP32's capabilities to support basic Linux functionalities—ideal for experimentation, learning, or running simple applications that traditionally require more robust hardware.

⚙️ How It Works

The emulator translates RISC-V instructions into instructions compatible with the ESP32, allowing the system to simulate a RISC-V processor environment and run a minimal Linux kernel.

💻 Flashing and Setup

1. Create the Filesystem Image (It's there already)

mklittlefs -c data -b 4096 -p 256 -s $((8*1024*1024)) littlefs.bin

2. Flash the Filesystem

esptool.py -b 1500000 write_flash 0x100000 littlefs.bin

3. Build and Flash the Firmware

idf.py flash monitor

Note

Make sure your ESP-IDF environment is correctly set up before starting. Tested with ESP32-S3 and a 16MB flash configuration. The Linux environment is minimal and designed for embedded purposes. ▶️ I'm on YouTube!
