### Unable to flash the device: `No loadable segments were found in the ELF file`

*Symptoms:*
```console
> cargo embed
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.04s
Config default
Target /home/user/embedded/target/thumbv7em-none-eabihf/debug/examples/init
WARN probe_rs::flashing::loader: No loadable segments were found in the ELF file.
Error No loadable segments were found in the ELF file.
```

*Cause:*

Cargo needs to know how to build and link the program to the requirements of the target device.
You therefore need to set the correct parameters in the `.cargo/config.toml` file.

*Fix:*

Add a `.cargo/config.toml` file with the correct parameters:
```toml
{{#include ../../05-meet-your-software/.cargo/config.toml}}
```

See [Embedded Setup](../../05-meet-your-software/embedded-setup.md) for further details.
