  all of the following require admin mode

  winget install --interactive --exact dorssel.usbipd-win usbipd wsl list # may need a new terminal window to refresh env usbipd wsl attach --auto-attach --busid ```

  • using cargo-espflash v2

  sh cargo espflash flash --monitor --example=esp32-c3-devkit-rust-1 --release --target=riscv32imc-esp-espidf

  • using espflash v2 (manual)

  sh cargo build --example=esp32-c3-devkit-rust-1 --release --target=riscv32imc-esp-espidf espflash flash --monitor target/riscv32imc-esp-espidf/release/examples/wifi
