i2c broken on esp32-c6

Hi,

i have the following test code:

use esp_idf_svc::hal::{delay::FreeRtos, i2c::*, prelude::*};

fn main() {
    esp_idf_svc::sys::link_patches();
    esp_idf_svc::log::EspLogger::initialize_default();
    log::info!("Hello, world!");
    let peripherals = Peripherals::take().unwrap();
    let i2c = peripherals.i2c0;
    let sda = peripherals.pins.gpio23;
    let scl = peripherals.pins.gpio22;
    let config = I2cConfig::new().baudrate(100.kHz().into());
    let mut i2c = I2cDriver::new(i2c, sda, scl, &config).unwrap();

    for addr in 110..=127 { //adjusted because I know the device address is 118
        println!("Scanning Address {}", addr as u8);
        // Scan Address
        let res = i2c.read(addr as u8, &mut [0], 10);
        // Check and Print Result
        match res {
            Ok(_) => println!("Device Found at Address {}", addr as u8),
            Err(_) => println!("No Device Found"),
        }
    }
    FreeRtos::delay_ms(10000);
}

the project was generated with cargo generate esp-rs/esp-idf-template cargo

on an esp32 the codes works as expected and shows me the address. The same code executed with an esp32-c6 shows sadly nothing (generated separate project for every chip). Any Idea what I could try? I really do not know what to do now after lots of testing and finally dig up an esp32 for testing.

Ok, I overlooked a pinout definition and found LP-I2C-SDA and SCL on pin 6 and 7.
Configured with this it now detects the I2C devices.
Sry for the noise.
On my other boards SDA/SCL was every time mentioned on the board itself behind the PIN number. No SDA/SC: reference on this board. Thought it was freely configurable cause no reference on the board and the method allowed 2 random pins.

Edit: Now with esp-idf v5.2 it seems to be more stable in some first tests. Before it was detected once and then never again.
