This is a spurious error that occurs only once on a new development kit. Running the command again should make the error go away. If you still get the error run `RUST_LOG=probe_rs=debug cargo flash --chip nRF52840_xxAA --bin hello ` once.
## 'erase_sector' failed with code 1
``` console
$ cargo flash --chip nRF52840_xxAA --bin hello

Error failed to flash app: The execution of 'erase_sector' failed with code 1
