Invalid app image header on esp32c6 #850
Description
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.
