Tool/software:
Provide the steps to integrate SDL functional safety modules such as BIST, POK, VTM and TOG with the PDK Boot Application.
When the Boot Application is operating in DDR, it indicates that it is functioning within the Main Domain. It is important to note that any BIST assessments that may affect the overall functionality of the Main Domain cannot be executed from the Boot App. This precaution is necessary to prevent potential corruption of the Boot App itself.
The below PBIST tests must therefore be excluded from Boot App as they should be followed by a Main Domain reset before starting the Boot App.
In the case of the board booting in SD or eMMC boot mode, caution should be exercised when running the following tests, as they impact the SD/eMMC drivers:

**NOTE: These patches are validated on J784s4 SDK 9.1 sequentially to enable all four modules. If you wish to enable any specific module, apply the changes manually. If any other SOC or a different version of the SDK is being used, please port the changes similarly. **
To boot to Linux through the PDK BootApp, follow the below mentioned steps after applying the patches shared above.
Generate lateapps by using the following commands
goto <RTOS SDK>/<PDK>/packages/ti/boot/sbl/example/boot_app/scripts
Run ./generate_lateapps.sh j784s4_evm
Multicore images(lateapps) will be generated in <PDK>/packages/ti/boot/sbl/example/boot_app/multicore_images/j784s4_evm/.
multicore_MCU2_0_MCU2_1_stage1.appimage corresponds to lateapp1, multicore_DSPs_MCU3_0_MCU3_1_MCU4_0_MCU4_1_stage2.appimage corresponds to lateapp2 and multicore_MPU1_0_stage3.appimage corresponds to lateapp3.
Copy sbl_mmcsd_img_mcu1_0_release.tiimage present in <PDK>/packages/ti/boot/sbl/binary/j784s4_evm/mmcsd/bin as tiboot3.bin to the boot partition of SD card
Copy tifs.bin present in <PDK>/packages/ti/drv/sciclient/soc/V6 to the boot partition of SD card.
goto <RTOS SDK>/<PDK>/packages/ti/build and build boot_app_mmcsd_linux by using the following command:
make BOARD=j784s4_evm CORE=mcu1_0 boot_app_mmcsd_linux -sj
Copy sbl_boot_app_mmcsd_linux_j784s4_evm_mcu1_0_freertos_TestApp_release.appimage present in <PDK>/packages/ti/boot/sbl/example/boot_app/binary/j784s4_evm/mmcsd as app to the boot partition of SD card.
Copy stage1 image as lateapp1, stage2 image as lateapp2 and stage3 image as lateapp3 to the boot partition of SD card.
Copy atf_optee.appimage, tidtb_linux.appimage, tikernelimage_linux.appimage present in<PDK>/packages/ti/boot/sbl/tools/BootApp_binaries/linux/j784s4_evm to the boot partition of SD card.
