OpenTitanTool

The OpenTitanTool is a CLI tool for interacting with a device via the various platforms available for development.

Operations supported by OpenTitanTool include:

• Flashing a bitstream to an FPGA board.
• Bootstrapping (flashing) software onto a device.
• Connecting to a device’s console.
• Manipulating a device’s GPIO pins, particularly for “strapping”.

OpenTitanTool is written in Rust and built using Bazel. It is used throughout the repository for executing tests.

To build and run the tool manually:

bazel build //sw/host/opentitantool
bazel run //sw/host/opentitantool -- help
