xtask

Helper utility for building and flashing ESP32 app crates under apps/. This crate is not published to crates.io.

Table of Contents

Overview

xtask resolves a short target name (or .rs path) to a Cargo binary, injects the Xtensa target and linker flags, and runs the build through the ESP toolchain.

Usage

Run from the repo root:

cargo xtask run ex-smoltcp
cargo xtask build qa-runner

Debug build:

cargo xtask run ex-embassy-net --debug

Pass args to the target:

cargo xtask run ex-esp-hal -- --extra-arg

Targets

Target Resolves To
qa-runner, qa apps/qa-runner/qa_runner.rs
ex-esp-hal apps/examples/esp_hal_integration.rs
ex-esp-hal-async apps/examples/esp_hal_async.rs
ex-smoltcp apps/examples/smoltcp_echo.rs
ex-embassy, ex-embassy-net apps/examples/embassy_net.rs

Notes

  • If no command is supplied, build is assumed.
  • --debug selects a debug build (release is the default).
  • -- passes arguments to the target binary.
  • ESP_LOG, ESP_IDF_VERSION, and CARGO_TARGET_DIR are defaulted if unset.
