* adding explicit nots like this:

```
[target.'cfg(all(target_arch = "riscv32", feature = "defmt", not(feature = "println")))']
runner = "probe-rs run --chip=esp32c6"

[target.'cfg(all(target_arch = "riscv32", feature = "println", not(feature = "defmt)))']
runner = "espflash flash --monitor"
```

give the same result
