Rust on ESP32 STD "Hello, World" app. A "Hello, world!" STD binary crate for the ESP32[XX] and ESP-IDF.

Overview

Rust on ESP32 STD "Hello, World" app

A "Hello, world!" STD binary crate for the ESP32[XX] and ESP-IDF.

This is the crate you get when running cargo new rust-esp32-std-mini, but augmented with extra configuration so that it does build for the ESP32[XX] with ESP-IDF and STD support.

Build

  • Install the Rust Espressif compiler fork and the Espressif LLVM Clang fork using either pre-built binaries or follow the directions to build your own;
    • This is necessary, because support for the Xtensa architecture (ESP32 / ESP32-S2 / ESP32-S3) is not upstreamed in LLVM yet
  • Switch to the esp toolchain from the pre-built binaries: rustup default esp
    • NOTE: For ESP32-C3 - which runs a RiscV32 chip - you can just use the stock nightly Rust compiler, and a recent, stock Clang (as in Clang 11+)
    • (You can do this by issuing rustup install nightly and then rustup default nightly instead of installing/building the Rust & Clang ESP forks and switching to their esp toolchain as advised above)
  • If using the custom Espressif Clang, make sure that you DON'T have a system Clang installed as well, because even if you have the Espressif one first on your $PATH, Bindgen will still pick the system one
    • A workaround that does not require uninstalling the system Clang is to do export LIBCLANG_PATH=<path to the Espressif Clang lib directory> prior to continuing the build process
  • cargo install ldproxy
  • Clone this repo: git clone https://github.com/ivmarkov/rust-esp32-std-mini
  • Enter it: cd rust-esp32-std-mini
  • To configure the demo for your particular board, please uncomment the relevant Rust target for your board and comment the others. Alternatively, just append the --target <target> flag to all cargo build lines below.
  • Build: cargo build or cargo build --release

Flash

  • cargo install espflash
  • espflash /dev/ttyUSB0 target/[xtensa-esp32-espidf|xtensa-esp32s2-espidf|xtensa-esp32s3-espidf|riscv32imc-esp-espidf]/debug/rust-esp32-std-mini
  • Replace dev/ttyUSB0 above with the USB port where you've connected the board

Monitor

  • cargo install espmonitor

  • espmonitor /dev/ttyUSB0

  • Replace dev/ttyUSB0 above with the USB port where you've connected the board

  • The monitor should output more or less the following:

    sdkconfig.defaults ignored

    Hi. I'm having issues changing the SDK configuration. I'd like to disable logging in the bootloader and HAL as well as a few other things, which can be done by adding the following lines to sdkconfig.defaults:

    CONFIG_BOOTLOADER_LOG_LEVEL=0
    CONFIG_BOOTLOADER_WDT_ENABLE=n
    CONFIG_HAL_LOG_LEVEL=0
    CONFIG_LOG_DEFAULT_LEVEL=0
    CONFIG_ESP_SYSTEM_PANIC=ESP_SYSTEM_PANIC_PRINT_HALT
    

    After adding these lines to sdkconfig.defaults and running cargo build (with or without --release) I noticed that none of these changes were applied. My ESP32 was still displaying boot logs and calling panic!() would make the chip reboot instead of halting as specified above.

    I tried:

    • Adding ESP_IDF_SDKCONFIG_DEFAULTS = "sdkconfig.defaults" to the [env] section in .cargo/config.toml
    • Adding ESP_IDF_SDKCONFIG = "sdkconfig.defaults" to the [env] section in .cargo/config.toml
    • cargo clean; cargo build

    None of these helped. Is there extra configuration needed to make this work?

  • cmake template: remove panic_immediate_abort for new idf versions

    cmake template: remove panic_immediate_abort for new idf versions

    build-std-features=panic_immediate_abort causes panics to not print their error messages which is a bad developer experience. Similar to the Cargo template, do not set this flag for newer espidf versions.

    Hey,

    I am quite excited to get this to work. I have had quite a bit of trouble.

    What I am trying to do is to get something compiled and onto my ESP32.

    Might be more related to esp-idf-sys.

    Here is one of the things that I have tried to do.
