Module platform 

ESP32 platform build, flash, emulation, and package utilities.

The generated harness crate pins its own esp Rust toolchain via rust-toolchain.toml and selects the Xtensa target via .cargo/config.toml, so builds simply run cargo build inside the harness directory with the Xtensa GCC and clang library paths exported.

Structs

SerialPortSummary

Summary of a host serial port for device listing and board auto-detection.

Functions

build_esp32

Build the ESP32 firmware ELF for the configured chip.

built_esp32_binary_path

Resolve the built ESP32 firmware ELF path for the given profile.

clean_esp32

Clean Cargo build artifacts and packaged images for the ESP32 harness.

detect_esp_serial_port

Pick the serial port of a connected ESP32 board, if any.

esp_toolchain_envs

Environment variables required to drive the Espressif Rust toolchain for chip.

is_esp32_platform
