Yocto Project Reference Manual
For Yocto Rocko we recommend using Ubuntu 16.04 64-bit on a physical PC or inside a Virtual Machine:
- Set the number of CPUs to maximum possible
- Set the memory size to at least 4GB.
- Set the disk size to be at least 200GB. 300GB is better.
- Use Bridge for networking.
- Install the VMWare tools.
- If you have an extra hard drive you can use it as a physical partition and set your home directory to it.
- Update Ubuntu right after the first login.
Follow the links below and install all required packages on your machine.
Yocto Project Reference Manual
Please make sure your host PC is running Ubuntu 16.04 64-bit and install the following packages:

To get the BSP (Board Support Package) you need to have repo - the multiple git repository tool - installed.
Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow.
Install the repo utility:
mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Download the BSP source:
PATH=${PATH}:~/bin
mkdir ~/itron-fslc-yocto
cd ~/itron-fslc-yocto
repo init -u https://github.com/noritake-itron/itron-bsp-platform.git -b fsl-warrior
repo sync -j4
At the end of the commands, you have every metadata you need to start work with.
You can use any directory to host your build.
The source code is checked out at itron-fslc-yocto/sources.
To update BSP sources please use the following command:
repo sync -j4
You can use the command below to setup environment.
$ MACHINE=<tx070s|tx101s|tx070l|tx070u> DISTRO=<fslc-x11/fslc-framebuffer/fslc-wayland/fslc-xwayland> . setup-environment <build_directory_name>
You can find the information about the Yocto configuration in the link below:
You can build the standard toolchain or the toolchain the support for Qt5
To build the toolchain without the Qt support please use the following command:
bitbake meta-ide-support
bitbake meta-toolchain
To build the toolchain with the Qt support please use the following command:
bitbake meta-ide-support
bitbake meta-toolchain-qt
To compile applications that require libraries other than glibc you should build an SDK which contains development versions of all libraries in the rootfs image, and not just the basic toolchain.
When using the fsl-image-gui image:
bitbake -c populate_sdk fsl-image-gui
When using the fsl-image-qt5 image:
bitbake -c populate_sdk fsl-image-qt5
When you successfully build the toolchain you can install tools.
To install the toolchain without the Qt support please run:
tmp/deploy/sdk/fsl-imx-xwayland-glibc-x86_64-fsl-image-gui-aarch64-toolchain-4.19-warrior.sh
To install the toolchain with the Qt support please run:
tmp/deploy/sdk/fsl-imx-xwayland-glibc-x86_64-fsl-image-qt5-aarch64-toolchain-4.19-warrior.sh
Each time you wish to use the toolchain in a new shell session, you need to source the environment setup script:
source /opt/fsl-imx-xwayland/4.19-warrior/environment-setup-aarch64-poky-linux
export LDFLAGS=
or
source /opt/fsl-imx-wayland/4.19-warrior/environment-setup-aarch64-poky-linux
export LDFLAGS=
