Itron BSP platform

Repo installation

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 Yocto Rocko BSP for TX modules

Download the BSP source: 

$ PATH=${PATH}:~/bin
$ mkdir ~/itron-fslc-yocto
$ cd ~/itron-fslc-yocto
$ repo init -u https://bitbucket.org/noritake-itron/itron-bsp-platform.git -b rocko
$ 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.

Update Yocto Rocko BSP

To update BSP sources please use the following command:

$ repo sync -j4

Setup and build the toolchain

Setting the Yocto environment

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>
Note: <tx070s|tx101s|tx070l|tx070u> - please choose the proper machine
Note: <fslc-x11/fslc-framebuffer/fslc-wayland/fslc-xwayland> - please choose the proper distro name*
Note: <build_directory_name> - please select the directory name

Configure the Yocto system

You can find the information about the Yocto configuration in the link below:

Configure Yocto

Build the toolchain

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

###### << . 4 . >>

Install the toolchain

When you successfully build the toolchain you can install tools.

To install the toolchain without the Qt support please run:

$ tmp/deploy/sdk/fslc-x11-glibc-x86_64-meta-toolchain-armv7at2hf-neon-toolchain-2.4.1.sh
Note: the toolchain above is for the version with X11
Note: to run commands above you have to be inside the Yocto build directory

To install the toolchain with the Qt support please run:

$ tmp/deploy/sdk/fslc-framebuffer-glibc-x86_64-meta-toolchain-qt5-armv7at2hf-neon-toolchain-2.4.1.sh
Note: the toolchain above is for the framebuffer version with the Qt support
Note: to run commands above you have to be inside the Yocto build directory

###### << . 5 . >>

Use the toolchain

Each time you wish to use the toolchain in a new shell session, you need to source the environment setup script:

$ source /opt/fslc-fb/2.4.1/environment-setup-armv7at2hf-neon-fslc-linux-gnueabi
Note: the toolchain above is for the framebuffer version

or

$ . /opt/fslc-x11/2.4.1/environment-setup-armv7at2hf-neon-fslc-linux-gnueabi
Note: the toolchain above is for the version with X11
