Getting Start with LinRT BSP : Real-Time Linux Yocto BSP for i.MX and x86 SBC


Host Installation

Hardware recommendations

  • 4 CPUs cores minimum
  • RAM 4GB minimum, 8GB recommended
  • 160GB Hard Disk minimum for complete install new Host including LinRT BSP, or 100GB minimum free Hard Disk space for LinRT BSP install, (SSD HD recommended)

Using a Virtual Machine is possible but can increase the build time of BSP and SDK by 2.

Host Setup

This Wiki page PC Host Installation is written for Ubuntu 16.04 LTS (64-bit) Linux distribution (recommended with LinRT BSP), for other Linux distributions, see Yocto Project 2.4 documentation

To prepare Ubuntu System for the BSP building, follow the instructions below.
Updating the package database :

$ sudo apt-get update

Install Linux essentials packages for building an image with Yocto Project :

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib g++-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping libsdl1.2-dev xterm

Install additional packages for FSL Community/LinRT BSP :

$ sudo apt-get install autoconf libtool libglib2.0-dev libarchive-dev python-git xterm sed cvs subversion coreutils texi2html docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils libgl1-mesa-dev libglu1-mesa-dev mercurial automake groff curl lzop asciidoc u-boot-tools dos2unix mtd-utils pv libncurses5 libncurses5-dev libncursesw5-dev libelf-dev

LinRT users configuration

Git user PC Host configuration

Set your own git user information and on your PC Host system :

$ git config --global "" 
$ git config --global "Your Name"

RSA Key for LinRT sources access

To get LinRT BSP sources on our Git repositories you need to send a public RSA key from your PC Host to have access via SSH and HTTPS protocol.

To check if you already have a public RSA key, open a terminal and run the following :

$ ls ~/.ssh/id*.pub

If you have an existing public key RSA without a passphrase and you want to use it, you don’t need to generate a new key. You can directly go to the next paragraph “Share your public RSA Key with LinRT GIT server

Save the current keys in the backup folder before generating a new key :

$ mkdir -p ~/.ssh/backup
$ cp ~/.ssh/id* ~/.ssh/backup/

To generate a new public key and set its name id_rsa_linrt

ssh-keygen -t rsa -C ""
Generating public/private rsa key pair.
Enter file in which to save the key (/home/johndoe/.ssh/id_rsa): id_rsa_linrt

We recommend using a key without a passphrase to do not need to enter it each to you need to update LinRT sources from git repositories. Enter and re-enter an empty passphrase when prompted.
The command creates your default identity with its public and private keys. The whole interaction will look similar to the following :

ssh-keygen -t rsa -C ""
Generating public/private rsa key pair.
Enter file in which to save the key (/home/johndoe/.ssh/id_rsa): id_rsa_linrt
Created directory '/home/johndoe/.ssh/'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/johndoe/.ssh/.ssh/id_rsa_linrt.
Your public key has been saved in/home/johndoe/.ssh/.ssh/
The key fingerprint is:
The key's randomart image is:
+--[ RSA 2048]----+
|*o+*-o.          |
|.+.=o+ .         |
|. *.n o .        |
| . = E :         |
|    u . S        |
|   , . x         |
|     !           |
|                 |
|                 |

Add SSH config file for new RSA key id_rsa_linrt to use it with LinRT bitbucket git server :

$ nano ~/.ssh/config 
    IdentityFile ~/.ssh/id_rsa_linrt

Share your public RSA with the LinRT git server

To get LinRT BSP sources on our Git repositories you need to send a public RSA key from your PC Host to have access via SSH protocols.
To send your RSA key, you must open a Ticket with the selected category : Subscription and attach to the ticket your “” file.

LinRT Real-Time Linux Yocto BSP Attach File to Ticket

Note : this first ticket will not be deducted from your Subscription !
You should receive a confirmation from the Agent when your Git access is ready to use.
To install and build the BSP go to LinRT BSP Building Wiki page
