1Overview
This tutorial guides new developers how to build Yocto Linux with the MTK i500 based
development platform –SB52 board. It provides manuals for:
•Setting up a Linux® OS build machine.
•Building SB52 Yocto Linux images.
•Flashing the images to SB52 development board.
2Setting up your computer
To build the Yocto Linux source files, you need a 64-bit version of Ubuntu (18.04 is recommended.
But compatible with 16.04).
After installing the computer running Linux OS, check whether all the necessary packages are
installed.
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-
multilib build-essential chrpath socat cpio python python3 python3-pip
python3-pexpect xz-utils debianutils iputils-ping python3-git python3-
jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm g++ libstdc++6
lib32stdc++6 libpulse-dev libevent-dev ninja-build rpm2cpio libswitch-
perl
gn tools install
$ sudo apt-get install libssl-dev
$ wget -O gn http://storage.googleapis.com/chromium-
gn/3fd43e5e0dcc674f0a0c004ec290d04bb2e1c60e
$ sudo chmod 777 gn
Put the gn in build server /usr/bin/
Install adb and Fastboot
$ sudo apt-get install android-tools-adb android-tools-fastboot
Note: If your Ubuntu use default dash shell, please install bash shell to build image.
3Building the Yocto Linux for SB52
3.1Downloading the SB52 source
Please contact your Innocomm contact window to download the SB52 source code.
3.2Extracting the SB52 source
After you have set up a computer running Linux OS, extract the SB52 source tar by using the
following commands:
$ cd ~ (or any other directory you like)
$ unzip sb52-yocto.33.tar.xz.zip (need password)
$ tar -xJvf sb52-yocto.33.tar.xz
3.3Building Yocto Linux images
Full build
$ export TEMPLATECONF=${PWD}/meta/meta-innocomm/conf/base/sb52
$ source meta/poky/oe-init-build-env
SB52 Development Platform

$ bitbake innocomm-image-openmm-aiv
Note:
If you want a clean build, remove build and sstate-cache folder, and start from beginning.
Partial build
Partial compile can generate "boot","lk" image separately, also can verity build fail quickly.But
can’t generate “rootfs””userdata” images.
#Kernel
$ bitbake virtual/kernel -c cleansstate //clean
$ bitbake virtual/kernel -f //rebuild
#LK
$ bitbake lk -c cleansstate
$ bitbake lk –f
#Appmainprog and other target bb
$ bitbake appmainprog -c cleansstate
$ bitbake appmainprog
The images will be located in the below folder, if build is successful.
build/tmp/deploy/images/sb52
Note: All files under this folder are needed to flash the board
3.4Commercial License
Although Yocto Linux is open source, some licenses of modules/packages are commercial and
need to buy the license for your product.
Take AAC decoder plugin of gstreamer, gstfaad, as example, following modification should be
done to include it in the image.
1) Add gstreamer1.0-plugins-bad_%.bbappend
$ mkdir -p meta/meta-innocomm/recipes-multimedia/gstreamer
$ touch meta/meta-innocomm/recipes-multimedia/gstreamer/gstreamer1.0-
plugins-bad_%.bbappend
$ echo "PACKAGECONFIG += \" faad \\\"" > meta/meta-innocomm/recipes-
multimedia/gstreamer/gstreamer1.0-plugins-bad_%.bbappend
2) Fix wayland depend
In src/multimedia/gst-mtkwaylandsink/src/wayland.c
Change
#include <gst/wayland/wanland.h>
SB52 Development Platform
6
To
#include <wayland.h>
3) Add whitelist for fdd2 (please be NOTICED, the modification is for test only, if you want to
enable modules/packages for your product finally, please buy licenses)
In meta/meta-innocomm/conf/base/sb52/local.conf.sample, add following text.
LICENSE_FLAGS_WHITELIST = "commercial_faad2"
For more information about commercial license recipes, please refer to
https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#enabling-
commercially-licensed-recipes
4Flashing SB52 image
Use the command below to flash the board
$ sudo python flashimage.py
Full flash steps:
1. Plug out SB52 power cable
2. Plug in USB cable
3. Run flashimage.py
$ sudo python flashimage.py
usage: flashimage.py [-h] [-d] [-s] [-u] [-b] [-t] [-v] [-n] [--toolsdir TOOLSDIR]
