==Creating and building example Vivado project==
BELK/BXELK provides an example Vivado project for BORA/BORAX/BORALITE boards. This project allows to:
This article describes how two build this project. Two procedures are described, the former is command line based while the latter is GUI based.
The project is stored is a git repository, as described [[Build_system_(BORA_SOM/BELK)-L/Development/Build_system#Setting_up_the_Zynq_development_server_environment|here]].
It is assumed that the Zynq development environment has been set up properly (see [[Build_system_(BORA_SOM/BELK)-L/Development/Build_system|this page]] for more details).
===Command line based procedure===
**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/${BASE_NAME}/ip/${BASE_NAME}_processing_system7_0_0/ps7_init_gpl.* <U-boot_src_dir>/board/dave/bora/${UBOOT_PS7_DIR}/</code>
:*Follow [[BORA_SOM/BELK-L/Development/Building_U-Boot_(BELK/BXELK) Boot | U-boot build instructions]] to build U-boot using new PS configurations. '''Please note that the U-Boot binary images released along with BELK/BXELK were already built upon the <code>ps7_init_gpl.c</code> and <code>ps7_init_gpl.h</code> source files generated by the Vivado project described in this article'''. As such, it is not generally required to rebuild U-Boot.
:**The PS configurations are the same for Bora and BoraLite boards.
*The bitstream file is now present in <code><project_directory>/<prj_name>.runs/impl_1/${BASE_NAME}_wrapper.bit</code> and <code><project_directory>/<prj_name>.runs/impl_1/${BASE_NAME}_wrapper.bin</code>.
*Copy the <code>ps7_init_gpl.c</code> and <code>ps7_init_gpl.h</code> source files into U-boot source code directory using the following command example for Bora:
:<code>cp <project_directory>/<prj_name>.srcs/sources_1/bd/${BASE_NAME}/ip/<prj_name>_processing_system7_0_0/ps7_init_gpl.* <U-boot_src_dir>/board/dave/bora/${UBOOT_PS7_DIR}/</code>Follow [[BORA_SOM/BELK-L/Development/Building_U-Boot_(BELK/BXELK) Boot | 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'''.
