cargo install elf2uf2-rs
```
For boards with uf2 flashloaders you can use the following lines to run the examples:
Make sure .cargo/config contains the following (it should by default):
```toml
runner = "elf2uf2-rs -d"
```
```sh
export RPI_MOUNT_FOLDER=/media/RPI-RP2/
export EXAMPLE=pico_blinky; # See `cargo check --example` for valid values
cargo check --example $EXAMPLE && \
cargo objcopy --release --example $EXAMPLE -- -O binary target/$EXAMPLE.bin && \
uf2conv target/$EXAMPLE.bin --base 0x10000000 --family 0xe48bff56 --output target/$EXAMPLE.uf2 && \
cp target/$EXAMPLE.uf2 $RPI_MOUNT_FOLDER
cargo run --example pico_pwm_blink # Run `cargo run --example` for more examples
```
