Framework System

Rust libraries and tools to interact with the system.

The tool works on Linux, Windows and the UEFI shell. Download it from the latest GH Actions run on the main branch. Most features are supported on every "OS". See below for details.

Features

To check which features are supported on which OS and platform, see the Support Matrices.

Operating System Support

Firmware Information

Firmware Update

Note: Use fwupd.

System Status

All of these need EC communication support in order to work.

Get information about battery/AC (--power)
Get information about USB-C PD ports (--pdorts)
Get information about CCGX PD Controllers (--pd-info)
Show status of intrusion switches (--intrusion)
Show status of privacy switches (--privacy)
Check recent EC console output (--console recent)

Changing settings

Get and set keyboard brightness (--kblight)
Get and set battery charge limit (--charge-limit)
Get and set fingerprint LED brightness (--fp-brightness)

Communication with Embedded Controller

Framework Laptop 13 (Intel 11-13th Gen)
Framework Laptop 13 (AMD Ryzen)
Framework Laptop 16 (AMD Ryzen)
Port I/O communication on Linux
Port I/O communication on UEFI
Using cros_ec driver in Linux kernel
Using DHowett's Windows CrosEC driver

Prerequisites

Only Rustup is needed. Based on rust-toolchain.toml it will install the right toolchain and version for this project.

Building

MSRV (Minimum Supported Rust Version):

1.61 for Linux/Windows
1.68 for UEFI

# Running linter
cargo clippy

# Running autoformatter as a check
cargo fmt --check

# Fixing format issues
cargo fmt

# Building the library and tool
cargo build

# Building only the library
cargo build -p framework_lib

# Building only the tool
cargo build -p framework_tool
ls -l target/debug/framework_tool

# Build the UEFI application
# Can't be built with cargo! That's why we need to exclude it in the other commands.
make -C framework_uefi
ls -l framework_uefi/build/x86_64-unknown-uefi/boot.efi

Building on Windows or in general with fewer features:

# Because we're fetching a private dependency from git, it might be necessary
# to force cargo to use the git commandline. In powershell run:
$env:CARGO_NET_GIT_FETCH_WITH_CLI='true'

# Build the library and tool
cargo build --no-default-features --features "windows"

# Running the tool
cargo run --no-default-features --features "windows"

Cross compile from Linux to FreeBSD:

# One time, install cross tool
cargo install cross

# Make sure docker is started as well
sudo systemctl start docker

# Build
cross build --target=x86_64-unknown-freebsd --no-default-features --features unix

Running on Windows

Windows does not ship with a Chrome EC driver. However there is an open-source implementation that this tool can take advantage of. The project is hosted on GitHub and you can download pre-built binaries there.

The driver is not signed by Microsoft, so you will have to enable testsigning.

Running on ChromeOS

The application can run on ChromeOS but most commands rely on custom host commands that we built into the EC firmware of non-Chromebook Framework laptops. In theory you could add those patches to the Chromebook platform, build your own EC firmware and flash it.

Tests

Basic unit tests
Test parsing real binaries

Debugging

To debug, increase the verbosity from the commandline with -v. The verbosity levels are:

Commandline	Level
`-q`	No log
None	Error
`-v`	Warn
`-vv`	Info
`-vvv`	Debug
`-vvvv`	Trace

For example it is useful to check which EC driver is used:

> framework_tool --kblight -vvv
[DEBUG] Chromium EC Driver: CrosEc
[DEBUG] send_command(command=0x22, ver=0, data_len=0)
Keyboard backlight: 0%

> framework_tool --driver portio --kblight -vvv
[DEBUG] Chromium EC Driver: Portio
[DEBUG] send_command(command=0x22, ver=0, data_len=0)
Keyboard backlight: 0%
