Yes I'm quite sure, `cat .cargo/config.toml`:

```
[target.'cfg(all(target_arch = "arm", target_os = "none"))']
runner = "probe-rs run --chip STM32L431KCUx --speed 24000 --connect-under-reset"

rustflags = [
  "-C",
  "link-arg=-Tlink.x",
  "-C",
  "link-arg=-Tdefmt.x",
  "-C",
  "linker=flip-link",
  "-C",
  "link-arg=--nmagic",
]

[build]
target = "thumbv7em-none-eabihf" # Cortex-M4F and Cortex-M7F (with FPU)
```
