Building and flashing

ESP32 Feather V2:

• Install the esp rust toolchain and the espflash utility:

  cargo install espup
  espup install
  cargo install espflash

• Bring the toolchain installed this way into PATH:

  source ~/export-esp.sh

• Build the firmware image:

  cargo build --release

• Flash the image onto a board:

  espflash flash target/xtensa-esp32-none-elf/release/eos-sensor

• Alternatively, use

  espflash flash --monitor -L defmt target/xtensa-esp32-none-elf/release/eos-sensor

  to flash the image and attach to the device to receive logging output. cargo run is also mapped to this command for more convenient access.
