System Requirements

Building an image from source with Yocto necessitates a host system with the following specifications:

• OS: Ubuntu 20.04
• CPU: 4 Core
• RAM: 8/16GB RAM (more is preferable)
• Storage: 200 GB
• SWAP space: 16GB
  • If less memory is available, additional swap space may be necessary. Insufficient memory can lead to sluggish builds and sporadic build errors.
• Network
  • The host must be connected to a network with Internet access to download all necessary source code and tools.

Set up build environment on host PC

Install required packages

• Update the host package list

sudo apt-get update

• Install required packages

sudo apt-get install gawk wget git-core git-lfs diffstat unzip texinfo gcc-multilib g++-multilib build-essential \
	chrpath socat cpio python python3 python3-pip python3-pexpect python-dev \
	xz-utils debianutils iputils-ping libsdl1.2-dev xterm \
	language-pack-en coreutils texi2html file docbook-utils \
	python-pysqlite2 help2man desktop-file-utils \

	groff curl lzop asciidoc u-boot-tools libreoffice-writer \
	sshpass ssh-askpass zip xz-utils kpartx qemu bison flex device-tree-compiler bc rsync \
	cmake libusb-1.0.0-dev libzip-dev libbz2-dev pkg-config libssl-dev manpages-posix-dev bash \
	vim screen sudo libncurses5 zstd liblz4-tool

Switching to bash environment

TI Yocto utilizes oe-layersetup tool and it requires to run under bash environment.

By default, Ubuntu uses dash instead of bash. Please switch the default shell to bash using the command below:

echo "dash dash/sh boolean false" | debconf-set-selections
DEBIAN_FRONTEND=noninteractive dpkg-reconfigure dash

For ROVY-4VM

• Fetch Yocto source code:

git clone --branch kirkstone_6.1.y https://github.com/TechNexion/tn-ti-yocto-oe-layersetup.git

cd tn-ti-yocto-oe-layersetup

./oe-layertool-setup.sh -f configs/technexion/tda4vm_kirkstone_6.1.46-sdk-analytics-09.01.00-config.txt

• Build Yocto source code:

cd build
echo 'ARAGO_BRAND = "edgeai"' >> conf/local.conf
. conf/setenv
MACHINE=rovy-4vm bitbake -k tisdk-edgeai-image
