Firmware Test Suite (FWTS) is a test suite that performs sanity checks on firmware. It is intended to identify BIOS, UEFI, ACPI and many other errors and if appropriate it will try to explain the errors and give advice to help workaround or fix firmware bugs. It is primarily intended to be a Linux-centric firmware troubleshooting tool.

Stable release

We are continually finding new ways that firmware can be broken, and hence fwts is continually being improved to detect firmware issues. Every release cycle a stable version of fwts is uploading into Universe and occasional updates appear as bug fix releases. However, a PPA is provided containing more up-to-date version of fwts.

The stable PPA contains more stable updates, generally code that has been tested for quite a while and is thus less likely to contain new features that cause breakage. To install from this PPA use:

sudo add-apt-repository ppa:firmware-testing-team/ppa-fwts-stable
sudo apt-get update
sudo apt-get install fwts


Firmware Test Suite Live Image (fwts-live)

fwts-live is a bootable USB image that will automatically boot and run the Firmware Test Suite on both legacy BIOS as well as native UEFI Firmware (x86_64 only). The test results are stored on the USB device and can be analysed on the fly or later on another computer.
