RUST for Mindot

Building Compiling Envronment

• Install Rustup.

• Install toolchain.

  • RiscV target - RiscV chips like ESP32-CXX are already supported in stock Rust.
  • Xtensa target - we need follow the instruction steps for your operating system.

  Here, the new mindot will base on RiscV target chip.

• Build llvm Clang. You'll need the custom LLVM clang based on the Espressif LLVM fork for Rust STD support. we need follow instruction steps.

• Build APP.

  • Choose esp toolchain:
    • rustup default esp
    • For RiscV target, we can use nightly directly:
      • rustup install nightly
      • rustup default nightly
  • Set Clang libary directory. export LIBCLANG_PATH=<path to the Espressif Clang lib directory>
  • Install linker. cargo install ldproxy
  • Build image. cargo build

• Flash

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

• Monitor

  • cargo install espmonitor
  • espmonitor /dev/ttyUSB0

• For details, you can refer the demo.
