Mion docs has an excellent getting started page. In this section we will emphasize how easy it is to build Mion. First, make sure you have a machine compliant to the "Build host" requirements. Install a pristine Debian 10 and you should be go to go ...

# To obtain related mion layers:
git clone git@github.com:NetworkGradeLinux/meta-mion.git
# Obtain the mion hardware layer
git clone git@github.com:NetworkGradeLinux/meta-mion-bsp.git


Warning
titleNote

The above steps require you have a GitHub account and uploaded public key to your account. You'll also have to activate ssh-agent as the build script will fetch software from Git using SSH transport.

Even if the build process can be long depending on your build host, build duration can reach 30 minutes with a 32 cores machines. Subsequent builds will take significantly less time as a cache mechanism will avoid to to redo the whole build process.

Believe me, you are done !

Just wait the end of the build process and grab the freshly baked image.

And in just 1 minute (warning) you have installed a minimalistic OS on your bf2556x-1t. In this post we will stop here. However, in order to finalise the installation you'll to install INTEL P4 Software Development Environment as of course you'll want to run your P4 program on the bf2556x-1t. We will cover this subsequent installation in a subsequent post.
