We provide pre-compiled Ubuntu deb packages for the GitHub repositories listed above.
Setting up the jevois.usc.edu apt source
As of this writing, and for a desktop running Ubuntu 20.04 amd64:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys DD24C027
sudo add-apt-repository "deb https://jevois.usc.edu/apt focal main"
sudo apt update
sudo apt upgrade # see note below
sudo apt autoremove
sudo apt purge modemmanager
sudo usermod -aG dialout $USER # need to reboot to take effect
sudo usermod -aG video $USER # need to reboot to take effect
Note
Starting with JeVois v1.19.0, jevois.usc.edu now also hosts mirror copies of the Google Coral EdgeTPU and Hailo deb packages, so you do not need to pull those from their respective vendors.
Installing Ubuntu packages for JeVois-A33 development
Because the operating system that runs on JeVois-A33 is as small as possible and does not have a package management system, compilers, etc the overall strategy for JeVois-A33 is that we cross-compile all code on a desktop computer and place the compiled results into a staging area that will later be flashed to microSD.
Thus, all packages for JeVois-A33 are for Intel amd64 architecture and are to be installed on desktop, though some packages do contain cross-compiled code for the ARM processor of JeVois-A33. This cross-compiled code will be copied from staging to microSD.
jevois-opencv: OpenCV 4.x compiled for host computer with settings that match those used by the JeVois platform hardware. We install this package into /usr/share/jevois-opencv-4.x so that it will not interfere with any other OpenCV install you might have on your host system and that might be required by some other software.
jevois-host: JeVois core software compiled for execution on a host computer
jevois-platform: JeVois core software cross-compiled for execution on the JeVois platform hardware
jevoisbase-host: JeVois base modules compiled for execution on a host computer
jevoisbase-platform: JeVois base modules cross-compiled for execution on the JeVois platform hardware
jevois-sdk: Compiled bootloaders, root filesystem, and other config files.
jevois-sdk-dev: Compiled cross-compilers and cross-compiled libraries for the JeVois platform architecture.
As jevois-sdk-dev brings all the others as dependencies, getting up and running with JeVois development now just means one apt-get install command.
If you want to be able to flash a microSD card using jevois-flash-card:
sudo apt install jevois-sdk
If you want to be able to cross-compile new modules for JeVois platform hardware:
sudo apt install jevois-sdk-dev
If you want to be able to recompile the platform Linux kernel or change the platform O.S. or add new buildroot packages to the platform:
You need to rebuild jevois-sdk from source. Follow the instructions in the INSTALL file of the jevois repository at https://github.com/jevois.
Installing Ubuntu packages for JeVois-Pro development
Because JeVois-Pro runs a full Ubuntu operating system, installing packages on the camera is done as you would do for a normal computer.
The following packages are available at https://jevois.usc.edu for amd64 (to be installed on a desktop):
jevoispro-opencv: OpenCV 4.x compiled for host computer with settings that match those used by the JeVois-Pro platform hardware. We install this package into /usr/share/jevois-opencv-4.x so that it will not interfere with any other OpenCV install you might have on your host system and that might be required by some other software.
jevoispro-openvino: Intel neural network framework OpenVino compiled for host computer with settings that match those used by the JeVois platform hardware. We install this package into /usr/share/jevoispro-openvino-x so that it will not interfere with any other OpenVino install you might have on your host system and that might be required by some other software.
jevoispro-host: JeVois core software compiled for execution on a host computer.
jevoisprobase-host: JeVois base modules compiled for execution on a host computer.
jevoispro-platform: JeVois core software cross-compiled for arm64 processor as a support package that will provide the necessary ARM libraries to allow you to later cross-compile your own machine vision modules.
jevoisprobase-platform: JeVois base modules cross-compiled for arm64 processor as a support package that will provide the necessary ARM libraries to allow you to later cross-compile your own machine vision modules.
jevoispro-sdk-dev: Cross-compiled operating system and libraries to be installed on host to support cross-compilation of JeVois software for the platform. That is, installing jevoispro-sdk-dev on your desktop will allow you to cross-compile jevois and jevoisbase for platform, finding the necessary cross-compiled libraries that may be needed.
The following packages are available at https://jevois.usc.edu for arm64 (to be installed on JeVois-Pro):
jevoispro-opencv: OpenCV 4.x compiled for JeVois-Pro. We install this package into /usr/share/jevois-opencv-4.x on the camera.
jevoispro-openvino: Intel neural network framework OpenVino compiled for JeVois-Pro. We install this package into /usr/share/jevoispro-openvino-x on the camera.
jevoispro-platform: JeVois core software cross-compiled for execution on the JeVois-Pro platform hardware, as a native package for arm64.
jevoisprobase-platform: JeVois base modules compiled for execution on the JeVois-Pro platform hardware, as a native package for arm64.
Note
Installing jevoispro-sdk-dev will pull all the other packages automatically as dependencies.
Here is a walkthrough of what you should see:
Which packages to install on a desktop host for JeVois-Pro?
If you just want to run JeVois software (jevois-daemon) on your host computer with a standard webcam:
Yes, this will pull over 500 dependent packages, this is normal, just say Yes to install them all. They include many libraries used by JeVois, the Coral libraries, Boost, OpenCV and OpenVino, etc.
If you want jevois and jevoisbase cross-compiled for the platform hardware as support packages to be installed on your host (needed to later cross-compile your own modules from source):
If you want to be able to cross-compile jevois, jevoisbase, or new modules for JeVois platform hardware:
sudo apt install jevoispro-sdk-dev
If you want to be able to recompile the platform Linux kernel or change the platform operating system:
You need to rebuild jevoispro-sdk from source using rebuild-os.sh as described below.
Which packages to install on the JeVois-Pro smart camera?
Note
The apt source jevois.usc.edu and those for Google Coral are already configured on the microSD, so you do not need to add them to your camera using the add-apt-repository commands detailed above.
jevoispro-opencv, jevoispro-openvino, jevoispro-platform, and jevoisprobase-platform are already pre-installed on the microSD.
The easiest to run the commands below is to switch JeVois-Pro to Console boot as explained in JeVois-Pro Quickstart user guide and to login as user root with password jevois
If you want to update jevoispro-platform and jevoisprobase-platform to the latest official version published at jevois.usc.edu:
sudo apt update
sudo apt upgrade
If you accidentally messed-up your jevois or jevoisbase on microSD (e.g., deleted some critical files) and want to re-install the latest official version published at jevois.usc.edu:
sudo apt purge jevoispro-platform jevoisprobase-platform
# get the debs you created onto your microSD
dpkg -i jevoispro-platform-XXX_arm64.deb
dpkg -i jevoisprobase-platform-XXX_arm64.deb
JeVois-A33 operating system source download and build from scratch
This only recommended for advanced programmers who want to modify the Linux kernel or operating system of JeVois.
JeVois-Pro operating system source download and build from scratch
This only recommended for advanced programmers who want to modify the Linux kernel or operating system of JeVois-Pro. If you just need the cross-compiled operating system so that you can compile and link custom code, install the jevoispro-sdk-dev deb package instead.
git clone https://github.com/jevois/jevoispro-sdk.git
cd jevoispro-sdk
./rebuild-os.sh
It will take a very long time, possibly over 12 hours depending on your computer and network speeds.
Note
If you want to also re-create the jevoispro-sdk-dev deb package so that you can later install it on another desktop computer, use ./rebuild-os -deb
Here is a walkthrough of what you should see when running rebuild-os.sh:
