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

The following operating environments are supported.

• Linux
• Windows
• UEFI
• FreeBSD

Most functionality depends communication with the EC. For Linux and Windows there are dedicated drivers. On UEFI and FreeBSD raw port I/O is used - on Linux this can also be used as a fallback, if the driver is not available or not working.

Many actions require root. First build with cargo and then run the binary with sudo:

cargo build && sudo ./target/debug/framework_tool

Running on Windows

On newly released systems since 2025 the Framework driver installer includes the EC driver. This includes Framework 12, Framework 13 AMD Ryzen AI 300, Framework Desktop.

Previous platforms will be enabled next.

Installing: winget install FrameworkComputer.framework_tool

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

Version Check

Check if the firmware version is what you expect, returns exit code 0 on succcess, 1 on failure.

# Check which devices it's available for
> ./framework_tool --device
  [possible values: bios, ec, pd0, pd1, rtm01, rtm23, ac-left, ac-right]

For more information try '--help'

# Successful compare
> ./framework_tool --device bios --compare-version 03.01
Target Version "03.01"
Comparing BIOS version "03.01"
Compared version:   0
> echo $?
0

# Failed compare
> ./framework_tool --device bios --compare-version 03.00
    Finished dev [unoptimized + debuginfo] target(s) in 0.05s
Target Version "03.00"
Comparing BIOS version "03.01"
Compared version:   1
Error: "Fail"

> echo $?
1

On UEFI Shell:

# Check if AC is attached on left side
Shell> fs0:framework_tool.efi --device ac-left --compare-version 1
Target Version "1"
Comparing AcLeft "1"
Comparison Result: 0
# It is
Shell> echo %lasterror%
0x0

# Check if AC is attached on right side
Shell> fs0:framework_tool.efi --device ac-right --compare-version 1
Target Version "1"
Comparing AcLeft "0"
Comparison Result: 1

# It is not
Shell> echo %lasterror%
0x1

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%

FreeBSD

sudo pkg install hidapi

# Build the library and tool
cargo build

# Running the tool
cargo run
