[ottool] Make the uart-clearing behavior optional In PR#13277, uart-clearing was added to prevent random leftovers in the host's receive buffer from affecting ROM detection and test pass/fail detection. Unfortunately, this changed the behavior of opentitantool in such a way that one could no longer keep a `opentitantool console` open in one windows while bootstrapping in another without specifying `--no-uart-clear-rx=true`. Since the primary use case for uart buffer clearing is test automation, test automation should enable its preferred behavior and not cause an end-user usability change. 1. Do not use a negative-named option. Negatively named options are confusing. 2. Add `--uart-clear` to all test-driven invocations of `bootstrap`. Signed-off-by: Chris Frantz <cfrantz@google.com>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
