*At the end of the bitstream build process, the <code>build_project_build_prj_*</code> script allows to automatically export hardware and lauch SDK.*The bitstream file is now present in <code><bora_repo>/vivado/${PRJ_FOLDER}.runs/impl_1/${BITSTREAM_FILE}.bit</code> and <code>.bin</code> format at <code><bora_repo>/vivado/bora${PRJ_FOLDER}.runs/impl_1/bora_wrapper${BITSTREAM_FILE}.bin</code>.
*By default FSBL is not used anymore in the boot process. U-Boot SPL (first-stage bootloader) is used instead. PS configuration files are used to build U-boot binaries.
**Copy the <code>ps7_init_gpl.c</code> and <code>ps7_init_gpl.h</code> source files into U-boot source code directory using the following command example for Bora:
:<code>cp <bora_repo>/bd/bora${PRJ_FOLDER}/ip/bora_processing_system7_0_0${PS7_FOLDER}/ps7_init_gpl.* <U-boot_src_dir>/board/dave/bora/bora${U-BOOT_PS7_FOLDER}/</code>
:*Follow [[Building_U-Boot_(BELK/BXELK) | U-boot build instructions]] to build U-boot using new PS configurations. '''Please note that the U-Boot binary images released along with BELK/BXELK were already built upon the <code>ps7_init_gpl.c</code> and <code>ps7_init_gpl.h</code> source files generated by the Vivado project described in this article'''. As such, it is not generally required to rebuild U-Boot.
:**The PS configurations are the same for Bora and BoraLite boards.
