I'm trying to start a embassy project for a STM32G4 microcontroller from scratch, but i'm facing an persistent error. When i use cargo embed to flash and run the code, i'm getting wrong characters for info! macros.

The code is:

`use embassy_executor::Spawner; use embassy_stm32::gpio::{Level, Output, Speed}; use embassy_time::Timer; use defmt::*; use {defmtrtt as , panicprobe as };

[embassy_executor::main]

async fn main(_spawner: Spawner) { let p = embassy_stm32::init(Default::default()); info!("Hello World!"); //defmt::println!("Hello, world!");

let mut led = Output::new(p.PA5, Level::High, Speed::Low);

loop {
    info!("high");
    led.set_high();
    Timer::after_millis(500).await;

    info!("low");
    led.set_low();
    Timer::after_millis(500).await;
}

}`

And this code is printing ... defmt 17:03:25.414 ~�7~ 17:03:25.414 W$�i$�$4�$�$�M$�&$�S$�i6K}mzz�r��bKbj�bb8&br�-bʀ5b

What could i possible do in this case?

Install the latest probe-rs version following the instructions at https://probe.rs/ . This comes with a newer version of cargo-embed that supports defmt. Alternatively you can run with probe-rs run, like the examples in this repo do.

Thanks @Dirbaio. It is working now with probe-rs run. cargo-embed still shows me dumb characters.

defmt printing wrong characters #2773
