IMPORTANT NOTES

Make sure additional components and network proxies are setup as mentioned in Build Environment Setup before proceeding to building PSDKRA
Make sure you dont 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

Quick steps to build vision apps for Linux+TI-RTOS mode

Edit file tiovx/build_flags.mak and modify below variables
BUILD_EMULATION_MODE=no
BUILD_TARGET_MODE=yes
BUILD_LINUX_A72=yes
PROFILE=release
Do below to build the source code using pre-built libraries provided in the SDK installer,
cd vision_apps
make vision_apps
The RTOS, Linux executable are stored below
vision_apps/out/J7/A72/LINUX/$PROFILE
vision_apps/out/J7/R5F/SYSBIOS/$PROFILE
vision_apps/out/J7/C66/SYSBIOS/$PROFILE
vision_apps/out/J7/C71/SYSBIOS/$PROFILE

Edit file tiovx/build_flags.mak and modify below variables
BUILD_EMULATION_MODE=yes
BUILD_TARGET_MODE=no
BUILD_LINUX_A72=no
PROFILE=release
Do below to build the source code using pre-built libraries provided in the SDK installer,
cd vision_apps
make vision_apps
The PC executables are stored below
vision_apps/out/PC/x64_64/LINUX/$PROFILE

To do a clean build of vision_apps do below,
cd vision_apps
make vision_apps_scrub

Default makefile flag values are set to build the SDK properly. However below flags are recommended to be changed by users to speed up their build time, execution speed and/or configure what to build depending on their specific requirements.
Edit below variables in tiovx/build_flags.mak. These flags will affect both tiovx as well as vision_apps

Makefile flag	Valid values (default value in bold)	Description
PROFILE	debug or release or all	"debug" for debug only build, "release" for release only build, "all" for both debug and release builds
BUILD_TARGET_MODE	yes or no	"yes" to build for SoC platform. In case you are building only for PC keep this to "no"
BUILD_LINUX_A72	yes or no	"yes" if you want to build for ARM Linux on A72. In case you are building for RTOS only mode, keep this to "no"
BUILD_EMULATION_MODE	yes or no	"yes" to build for PC emulation mode. In case you are building only for SoC keep this to "no"
BUILD_CT_*	yes or no	"yes" to enable OpenVX conformance tests for specific group of tests (CT). Typically during development one would keep all to "no" and only enable the required tests in respective CT "test_main.h"

Makefile flag	Valid values (default value in bold)	Description
BUILD_CPU_<cpu name>	yes or no	"yes" if you want that CPU in your build, else keep it to "no". Note, BUILD_CPU_MPU1, BUILD_CPU_MCU2_1 MUST be kept as "yes"
BUILD_APP_TIRTOS_LINUX	yes or no	"yes" to build Linux+RTOS mode binaries for selected CPUs. Keep to "no" if you are not interested in Linux+RTOS binaries. By default this is set to BUILD_LINUX_A72

Edit vision_apps/apps/basic_demos/app_tirtos/common/app_cfg*.h for additional build time configuration,
Note, additional #define's are defined in these files, but only ones which typical users need to customize are listed below.

File	#define	Description
app_cfg.h	ENABLE_IPC_<cpu name>	#undef these to disable a CPU from the system, #define to enable in the system Note, this must match the BUILD_CPU_<cpu name> vision_apps/vision_apps_build_flags.mak
app_cfg_mcu2_1.h	ENABLE_DSS_HDMI	#define this to enable HDMI display via Infotainment daughter card, make sure to #undef ENABLE_DSS_EDP as well
^	ENABLE_DSS_EDP	#define this to enable eDP display via base EVM, make sure to #undef ENABLE_DSS_HDMI as well
^	ENABLE_DSS	#undef this to disable display (both HDMI and eDP), if you don't have display panel or daughter card for display

Do below to see values of make configuration variables

make sdk_show_config
Do below to see additional make targets to do a granular SDK build
cd vision_apps
make sdk_help
Do below to build the full PSDKRA
cd vision_apps
make sdk
Do below to clean the full PSDKRA
cd vision_apps
