Ferrocene

Note

Ferrocene is the open-source qualified Rust compiler toolchain for safety- and mission-critical. Qualified for automotive, industrial and medical development.

Note

Ferrocene requires a (paid) license to use.

Ferrocene uses criticalup, its variant of rustup, to manage installing its toolchain and components. Once installed, wrapping regular Rust commands like cargo and rustc with criticalup run enables using the qualified tooling.

The Ariel OS build system seamlessly integrates this for targets supported by Ferrocene (currently all Cortex-M).

Installing Ferrocene

Please refer to the official Ferrocene documentation and the criticalup User Guide for instructions.

Using Ferrocene with Ariel OS

To select the Ferrocene toolchain, enable the ferrocene laze module.

Example:

$ laze -Cexamples/hello-world build --builders nrf52830dk --select ferrocene

Alternatively, add ferrocene to the laze modules of your application.
