Prerequisite

Repo and Git

Install the repo bootstrap binary:

$  mkdir ~/bin
$  export PATH=~/bin:$PATH
$  curl https://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$  chmod a+x ~/bin/repo

Alternatively, in Ubuntu, repo may be installed as part of the phablet-tools package.

Install Git and configure user name and e-mail. Below is an example for Debian-based systems:

$ sudo apt install git
$ git config --global user.name "John Doe"
$ git config --global user.email johndoe@example.com

Building RCU Image

Create a directory for your OE-Core setup to live in and clone the meta-information:

$ mkdir ${HOME}/oe-core
$ cd ${HOME}/oe-core
$ repo init -u https://github.com/ni/ateccgen2-manifest.git -b $GITBRANCH -m ateccgen2-manifest.xml
$ repo sync

Replace $GITBRANCH with the branch name that you would like to sync the manifest from, e.g. main

Source the file export to setup the environment:

$ . export

Build the image:

$ bitbake ateccgen2-minimal-image
