ESP32 Emulation Environment

ESP32 Emulated Environment (WIP)

An Qemu-based emulation environment for the Espressif ESP32 board on Docker 🐳 .

TL;DR

• $ docker run -it mluis/qemu-esp32
• $ idf
• $ make -C program
• $ ./flash.sh program/build/emulation.bin
• $ qemu-system-xtensa -nographic -M esp32 -m 4 -drive file=flash.bin,if=mtd,format=raw -nic user,model=open_eth,hostfwd=tcp::80-:80 -s

Building and Running

• $ docker build . -t qemu-esp32
• $ docker run --name qemu-esp32 --rm -i -t qemu-esp32 bash
• $ idf

Optional: Before compiling one might want to configure dependencies

• $ make -C program menuconfig

Running the example

• $ make -C program
• $ ./flash.sh program/build/emulation.bin
• $ qemu-system-xtensa -nographic -M esp32 -m 4 -drive file=flash.bin,if=mtd,format=raw -nic user,model=open_eth,hostfwd=tcp::80-:80 -s
