esp8266 compiled, but not works.

[NsdHSO]

I want to be able toggle the default led from esp8266. For the moment I want to run a loop in the esp, and to see the logs.

For the moment I builded this program

fn main() {
    esp_idf_sys::link_patches();
    // Loop to toggle the LED 20 times
    for i in 0..20 {
        println!("{} Toggle", i);
    }
}

cargo build

all works good.

but when I want to flesh, Flashing has completed, but I got something like.

If anyone has encountered this problem before and could help me, I would be grateful.

esp8266 will never be supported by the esp-idf-* crates.
Initially, we implemented "some" support, in the hope/anticipation that ESP-IDF will be ported to esp8266, but this would never happen.

We need to remove any reference to esp8266 from esp-idf-sys.

[ivmarkov]

The closest supported chip to esp8266 is esp32c3.
You can use any esp32* chip but it seems esp32c3 specifically is even pin-compatible with esp8266.

Because it does not work, will never work, and there is nobody who is willing to support esp8266. It is really time to move on to a newer chip.
