I tested it manually by compiling the cargo-esflash binary and flashing my home sensor project onto a esp32 dev board: https://github.com/etiennetremel/esp32-home-sensor.

Not sure if this is the right thing to do, but the project make use of Cargo features to enable/disable sensors during compile time.

For example, if I want to connect 2 sensors to the dev board (in this case sds011 and bme280), I can use the following command:

../../esp-rs/espflash/target/release/cargo-espflash espflash flash --release --no-default-features --features sds011,bme280
