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/
Build GUI demo image
$ MACHINE=am62x-var-som bitbake var-default-image
Program SD Card
The wic image fully supports booting from an SD Card. Use the command below to write it to an SD Card:
$ xzcat arago-tmp-external-arm-glibc/deploy/images/am62x-var-som/var-default-image-am62x-var-som.wic.xz | sudo dd of=/dev/sdX bs=1M && sync
NOTE: The wic image does not support all features booting from eMMC. For example, /etc/fw_env.config is configured for the SD Card (/dev/mmcblk1)
