   - `espflash` requires framming bytes as when using `defmt` it also needs to print non-`defmt` messages, like the bootloader prints.
     - It's important to note that other `defmt`-enabled tools like `probe-rs` won't be able to parse these messages due to the extra framing bytes.

-- Both `esp-println` and `esp-backtrace` have a `defmt-espflash` feature, which adds framming bytes so `espflash` knows that is a `defmt` message.

+- `esp-backtrace` has a `defmt` feature that uses `defmt` logging to print panic and exception handler messages.

 ## Exercise
 
-✅ Make sure the `defmt-espflash` feature of `esp-println` and `esp-backtrace` are enabled.
+✅ Make sure the `defmt-espflash` feature of `esp-println`  is enabled.
+
+✅ Make sure the `defmt` feature of `esp-backtrace` is enabled.
