nixpkgs-esp-dev

Derivations for developing for ESP8266 and ESP32 on NixOS.

This repo contains derivations for:

• Toolchains (compiler, linker, etc.) for xtensa-lx106-elf and xtensa-esp32-elf built with the xtensa fork of crosstool-NG
• The xtensa crosstool-NG fork itself.
• esptool

The easiest way to get started is to use nix-shell with one of these:

• shell-esp32.nix: for ESP32 development with esp-idf
• shell-esp-open-rtos.nix: for ESP8266 development with esp-open-rtos

To add this as a nixpkgs overlay, clone this repo somewhere on your machine and symlink overlay.nix to a file in ~/.config/nixpkgs/overlays, eg. ~/.config/nixpkgs/overlays/esp-dev.nix.

Note: This currently is impure and requires sandboxing to be turned off. Run commands that build things from this repo with --option sandbox false.

Partly adapted from esp-open-sdk.
