Let's discover together how to utilize our script to download and set up the latest Yocto BSPs.
Prerequisites
To proceed you need to have:
- Linux system
- repo utility
Install Docker Engine on Ubuntu
Our script utilizes Docker in order to assure the compatibility between Yocto and Ubuntu versions.
To install Docker correctly you need to:
Setup the repository
Update the apt package index and install the following packages to allow apt to use a repository over HTTPS:
sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates \
curl gnupg-agent software-properties-common linux-generic
Add Docker\'s official GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint:
sudo apt-key fingerprint 0EBFCD88
You should get this same output:
pub rsa4096 2017-02-22 [SCEA]
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88
uid [ unknown] Docker Release (CE deb) <docker@docker.com>
sub rsa4096 2017-02-22 [S]
Use the following command to set up the stable repository:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable"
Install Docker Engine:
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
Download and use the setup script
First, you need to clone the git repository:
git clone https://github.com/engicam-stable/engicam-bsp-scripts.git
Go into the just created directory and launch the script to prepare the environment:
cd ~/engicam-bsp-scripts
./prepare_engicam_bsp --help
./prepare_engicam_bsp <branch> <version>
The next table will list all the available environments.
| branch | version |
|---|---|
| nxp | zeus |
| nxp | zeus-2.3 |
| nxp | gatesgarth |
| st | dunfell |
Important note: The previous table does not keep track of all available versions. To find the most recent one you can check the following link https://github.com/engicam-stable/engicam-bsp-scripts
For example:
./prepare_engicam_bsp nxp zeus-2.3
or:
./prepare_engicam_bsp st dunfell
This procedure may take some time to complete. Once it\'s finished you can find all source code in the /yocto folder.
Note: to return to the same Docker environment you just need to relaunch the same command used to set it up the first time.
Now you are ready to set up the environment variables for the Yocto version you chose.
