Working on my first esp-rs project, using a std configuration from esp-idf-template on an esp32c6.

Having deployment issues, so I have the following simple test:

fn main() {
    esp_idf_svc::sys::link_patches();

    esp_idf_svc::log::EspLogger::initialize_default();

    log::info!("Hello World!");
}

This runs correctly under Wokwi but fails to start on the esp32c6 with an Invalid app image header warning as follows

ELF file SHA256:

I am using an ESP-IDF install that I have checked out at v5.3.3 and have set MCU="esp32c6" in .cargo/config.toml.

I have also tried manually adding an sdkconfig file to the project (as the native process for using menuconfig with esp-rs seems to be undocumented).

Would be grateful for some pointers to help debug, please.
