Reference Design is only usable with the specified Vivado/Vitis/PetaLinux version. Do never use different Versions of Xilinx Software for the same Project.

Reference Design is available on:

• TE0726 "Zynqberry Demo1" Reference Design

Design Flow

Trenz Electronic provides a tcl based built environment based on Xilinx Design Flow.

See also:

• AMD Development Tools#XilinxSoftware-BasicUserGuides
• Vivado Projects - TE Reference Design
•  Project Delivery.

The Trenz Electronic FPGA Reference Designs are TCL-script based project. Command files for execution will be generated with "_create_win_setup.cmd" on Windows OS and "_create_linux_setup.sh" on Linux OS.

TE Scripts are only needed to generate the vivado project, all other additional steps are optional and can also executed by Xilinx Vivado/Vitis GUI. For currently Scripts limitations on Win and Linux OS see: Project Delivery Currently limitations of functionality

1. Run _create_win_setup.cmd/_create_linux_setup.sh and follow instructions on shell:

   Code Block
   language bash theme Midnight title _create_win_setup.cmd/_create_linux_setup.sh

2. Press 0 and enter to start "Module Selection Guide"
3. Createproject and follow instructions of the product selection guide, settings file will be configured automatically during this process.
   

   • (optional for manual changes) Select correct device and Xilinx install path on "design_basic_settings.cmd" and create Vivado project with "vivado_create_project_guimode.cmd"

     Note
     Note: Select correct one, see also Vivado Board Part Flow

     
     

4. Create hardware description file (.xsa file) for PetaLinux project and export to prebuilt folder

   Code Block
   language py theme Midnight title run on Vivado TCL (Script generates design and export files into "<project folder>\prebuilt\hardware\<short name>")
   TE::hw_build_design -export_prebuilt

   
   

   Info
   Using Vivado GUI is the same, except file export to prebuilt folder.

   
   

5. Create and configure your PetaLinux project with exported .xsa-file, see PetaLinux KICKstart
   
   • use TE Template from "<project folder>\os\petalinux"
   • use exported .xsa file from "<project folder>\prebuilt\hardware\<short name>" . Note: HW Export from Vivado GUI creates another path as default workspace.
   • The build images are located in the "<plnx-proj-root>/images/linux" directory
   • For 128MB and 64MB only:Netboot Offset must be reduced manually, see Config
6. (Optional) Configure the boot.scr file as needed, see Distro Boot with Boot.scr
7. Generate Programming Files with Vitis (recommended)
   1. Copy PetaLinux build image files to prebuilt folder
      

      • Copy u-boot.elf, image.ub and boot.scr from "<plnx-proj-root>/images/linux" to prebuilt folder
        

        Info
        "<project folder>\prebuilt\os\petalinux\<DDR size>" or "<project folder>\prebuilt\os\petalinux\<short name>"

        This step depends on Xilinx Device/Hardware for Zynq-7000 series copy u-boot.elf, system.dtb, image.ub and boot.scr from "<plnx-proj-root>/images/linux" to prebuilt folder for ZynqMP copy u-boot.elf, system.dtb, bl31.elf, image.ub and boot.scr from "<plnx-proj-root>/images/linux" to prebuilt folder for Microblaze ...

        
        

   2. Generate Programming Files with Vitis

      Code Block
      language py theme Midnight title run on Vivado TCL (Script generates applications and bootable files, which are defined in "test_board\sw_lib\apps_list.csv")
      TE::sw_run_vitis -all TE::sw_run_vitis (optional; Start Vitis from Vivado GUI or start with TE Scripts on Vivado TCL)

      
      

      Note
      TCL scripts generate also platform project, this must be done manually in case GUI is used. See Vitis

      
      

8. Generate Programming Files with Petalinux (alternative), see PetaLinux KICKstart

Programming

Xilinx documentation for programming and debugging: Vivado/Vitis/SDSoC-Xilinx Software Programming and Debugging

Get prebuilt boot binaries

1. Run _create_win_setup.cmd/_create_linux_setup.sh and follow instructions on shell
2. Press 0 and enter to start "Module Selection Guide"
   1. Select assembly version
   2. Validate selection

   3. Select Create and open delivery binary folder

      Info
      Note: Folder "<project folder>\_binaries_<Article Name>" with subfolder "boot_<app name>" for different applications will be generated

      
      

QSPI-Boot mode

       Option for Boot.bin on QSPI Flash and image.ub and boot.scr on SD or USB.

1. Connect JTAG and power on the board
2. Set the dip switch S1 to ON state. (JTAG only mode)
   

   Note
   Note: Dip switch S1 exists only for boards with PCB REV04 or later.

3. Open Vivado Project with "vivado_open_existing_project_guimode.cmd" or if not created, create with "vivado_create_project_guimode.cmd"

   Code Block
   language py theme Midnight title run on Vivado TCL (Script programs BOOT.bin on QSPI flash)
   TE::pr_program_flash -swapp u-boot TE::pr_program_flash -swapp hello_te0726 (optional)

   
   

4. After programming the QSPI set the dip switch S1 to OFF again. (QSPI boot mode)
5. Copy image.ub and boot.scr on SD or USB
   
   • use files from (<project foler>/_binaries_<Articel Name>)/boot_linux from generated binary folder,see: Get prebuilt boot binaries
   • or use prebuilt file location, see <design_name>/prebuilt/readme_file_location.txt
   • Important: Do not copy Boot.bin on SD(is not used see SD note), only other files.
6. Copy init.sh on SD-Card
   • location: <design_name>/misc/sd/
7. Insert SD-Card

SD

Xilinx Zynq devices in CLG225 package do not support SD Card boot directly from ROM bootloader. Use QSPI for primary boot and SD for secondary boot (u-boot)

JTAG

Not used on this Example.

Usage

1. Prepare HW like described in section Programming
2. Connect UART USB (most cases same as JTAG)
3. Set the S1 dip switch to OFF for setting the board on the QSPI boot mode 

4. Insert SD Card with image.ub

   Tip

   Starting with Petalinux version 2020.1, the industry standard "Distro-Boot" boot flow for U-Boot was introduced, which significantly expands the possibilities of the boot process and has the primary goal of making booting much more standardised and predictable. The boot options described above describe the common boot processes for this hardware; other boot options are possible. For more information see Distro Boot with Boot.scr

   
   

5. Power On PCB
