Installing required packages

Please make sure your host PC is running Ubuntu 18.04/20.04/22.04 64-bit and is up to date:

 $ sudo apt-get update && sudo apt-get dist-upgrade

Then, install the following packages:

$ sudo dpkg --add-architecture i386
$ sudo apt update && sudo apt install build-essential autoconf \
       automake bison \
       flex libssl-dev bc u-boot-tools \
       python diffstat \
       texinfo gawk chrpath dos2unix \
       wget unzip socat doxygen libc6:i386 \
       libncurses5:i386 libstdc++6:i386 \
       libz1:i386 g++-multilib \
       git python3-distutils python3-apt
$ sudo dpkg-reconfigure dash

Install Toolchains to home directory

$ cd ~
$ wget  && \
   tar -Jxvf  -C $HOME && \
   wget  && \
   tar -Jxvf  -C $HOME

Download Yocto and setup environment

Download the source code:

$ mkdir ~/var-ti-yocto && cd ~/var-ti-yocto
$ git clone  tisdk
$ cd tisdk
$ ./oe-layertool-setup.sh -f 

Next, setup the environment. The above commands are only required for the very first build setup: whenever restarting a newer build session (from a different terminal or in a different time), you can skip the full setup and just run:

$ cd build
$ . conf/setenv
$ export TOOLCHAIN_PATH_ARMV7=$HOME/ && \
     export TOOLCHAIN_PATH_ARMV8=$HOME/
