Using
Set as your cargo runner, e.g. in your .cargo/config.toml file:
[target.thumbv7em-none-eabihf]
runner = "qemu-run -machine lm3s6965evb"
It will execute qemu-system-arm, pass the given -machine argument, pass
additional arguments to configure semihosting, and pipe semihosting data into
defmt-decoder to be decoded and printed to the console.
Run qemu-run --help to see a list of other command-line arguments available.
