IMPORTANT NOTES

Make sure you don't skip any of the steps mentioned below
${PSDKRA_PATH} refers to the path where Processor SDK RTOS Automotive (PSDKRA) is installed
${PSDKLA_PATH} refers to the path where Processor SDK Linux Automotive (PSDKLA) is installed
All folders like, pdk, tiovx, vision_apps mentioned in the user guide are relative to ${PSDKRA_PATH} unless explicitly stated otherwise.
The build is tested on Ubuntu (x86_64) 18.04 system and may not work on earlier or later Ubuntu systems.
20GB of free space is required to install and build PSDKRA
Make sure you have sudo access

Step 1: Download and Install PSDKRA

Download and Untar PSDKRA SDK Installer tarball psdk_rtos_auto_j7_xx_xx_xx_xx.tar.gz on a Ubuntu 18.04 (x86_64) machine.
cd {path/to/file}
tar xf psdk_rtos_auto_j7_xx_xx_xx_xx.tar.gz

Step 2: Download and install PSDKLA

PSDKRA needs PSDKLA to build. Run the installer file ti-processor-sdk-linux-automotive-j7-evm-xx_xx_xx_xx-Linux-x86-Install.bin on the same Ubuntu 18.04 (x86_64) machine.
Follow instructions on screen to complete the installation
Copy below files (linux filesystem and linux boot files) from PSDKLA folder to base folder of PSDKRA
cp ${PSDKLA_PATH}/board-support/prebuilt-images/boot-j7-evm.tar.gz ${PSDKRA_PATH}/
cp ${PSDKLA_PATH}/filesystem/tisdk-rootfs-image-j7-evm.tar.xz ${PSDKRA_PATH}/

Step 3: Proxy Setup

In order to download and compile some components from next step, it is required that your PC network proxy is setup properly. Below instructions show how the network proxy is setup assuming a proxy server named "http://webproxy.ext.ti.com:80" for the domain "ti.com". Modify these appropriately for your network.

Proxy for wget

To set the "wget" proxy add below lines in ~/.wgetrc
http_proxy=http://webproxy.ext.ti.com:80
https_proxy=http://webproxy.ext.ti.com:80
ftp_proxy=http://webproxy.ext.ti.com:80
noproxy=ti.com

Proxy for http access

Setup HTTP proxy by adding below lines in your ~/.bashrc
export HTTPS_PROXY=http://webproxy.ext.ti.com:80
export https_proxy=http://webproxy.ext.ti.com:80
export HTTP_PROXY=http://webproxy.ext.ti.com:80
export http_proxy=http://webproxy.ext.ti.com:80
export ftp_proxy=http://webproxy.ext.ti.com:80
export FTP_PROXY=http://webproxy.ext.ti.com:80
export no_proxy=ti.com

Proxy for "apt-get"

Add below line in the file /etc/apt/apt.conf
Acquire::http::proxy "http://webproxy.ext.ti.com:80";

Proxy for "git"

Install corkscrew
sudo apt-get install corkscrew
Create a file ~/.gitconfig and add below content to it
[user]
email = <myemail>@ti.com
name = <myname>
[core]
gitproxy = none for ti.com
gitproxy = /home/<username>/git-proxy.sh
[http]
proxy = http://webproxy.ext.ti.com:80
[https]
proxy = http://webproxy.ext.ti.com:80
Create a file ~/git-proxy.sh and add below lines in it
#!/bin/sh
exec /usr/bin/corkscrew webproxy.ext.ti.com 80 $*
Make ~/git-proxy.sh as executable
chmod +x ~/git-proxy.sh

Proxy for "curl"

Add below line in ~/.curlrc file
proxy=http://webproxy.ext.ti.com:80

Step 4: Download and install additional dependencies

Note: 'sudo' permission is required to run below script and install some components using apt-get; In case you don't want to install packages with sudo permission pass below argument to this script
--skip_sudo; Open below file and install the packages installed with sudo apt install separately

Do below to download and install additional dependencies needed to build PSDKRA.
cd ${PSDKRA_PATH}
./psdk_rtos_auto/scripts/setup_psdk_rtos_auto.sh

Note
Make sure to call the script from ${PSDKRA_PATH} as shown above. DO NOT "cd" into psdk_rtos_auto/scripts and call the script
