On the host, run the following commands:
(inside) $ BOARD=hatch (inside) $ DUT=dut1 (inside) $ emerge-$BOARD fingerprint_study (inside) $ cros deploy $DUT fingerprint_study
Reboot the device.
Navigate to http://localhost:9000 in a web browser.
We will use a python virtual environment to ensure proper dependency versions and a mock ectool
in mock-bin. Note, the mock ectool will effectively emulate an immediate finger press when the study tool requests a finger press. This does not make use of the FPC python library.
Run the following command:
(in/out) $ ./host-run.sh
Finally, navigate to http://127.0.0.1:9000 in a web browser.
This is an alternative method to install the fingerprint study tool on a test device. It bypasses the Chrome OS/Gentoo dependencies and allows using providing a clean virtualenv for the execution on the test device.
# Optionally, you can build the virtual environment in a Docker container. # docker run -v$HOME/Downloads:/Downloads -it debian # On Debian, ensure that git, python3, python3-pip, and virtualenv are installed. (outside) $ sudo apt update && apt install git python3 python3-pip virtualenv # Grab the fingerprint study tool source (outside) $ git clone https://chromium.googlesource.com/chromiumos/platform2 # Create an isolated python3 environment (outside) $ virtualenv -p python3 /tmp/fpstudy-virtualenv (outside) $ . /tmp/fpstudy-virtualenv/bin/activate # Install fingerprint study dependencies (outside) $ pip3 install -r platform2/biod/study/requirements.txt # Copy the fingerprint study source (outside) $ cp -r platform2/biod/study /tmp/fpstudy-virtualenv # Bundle the virtual environment with study source (outside) $ tar -C /tmp -czvf /tmp/fpstudy-virtualenv.tar.gz fpstudy-virtualenv # For Docker with Downloads volume shared, run the following command: # cp /tmp/fpstudy-virtualenv.tar.gz /Downloads/
The output of these steps is the fpstudy-virtualenv.tar.gz
archive.
Transfer the fpstudy-virtualenv.tar.gz
bundle to the test device.
One such method is to use scp, like in the following command:
(in/out) $ scp fpstudy-virtualenv.tar.gz root@$DUTIP:/root/
On the test device, extract the bundle into /opt/google
, as shown in the following command set:
(device) $ mkdir -p /opt/google (device) $ tar -xzvf /root/fpstudy-virtualenv.tar.gz -C /opt/google
Enable the fingerprint study Upstart job.
(device) $ ln -s /opt/google/fpstudy-virtualenv/study/fingerprint_study_virtualenv.conf /etc/init (device) $ start fingerprint_study_virtualenv (device) $ sleep 2 (device) $ status fingerprint_study_virtualenv
To configure the number of fingers, enrollment taps, and verification taps expected by the fingerprint study tool, please modify /opt/google/fpstudy-virtualenv/study/fingerprint_study_virtualenv.conf
.

This is an untested method of building an entire Chrome OS image with the fingerprint_study package included.
(inside) $ BOARD=hatch (inside) $ USE=fpstudy ./build_packages --board=$BOARD (inside) $ ./build_image --board=$BOARD (inside) $ cros flash usb:// $BOARD/latest
