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

Reference Design is available on:

Design Flow

Reference Design is available with and without prebuilt files. It's recommended to use TE prebuilt files for first lunch.

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

See also:

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/SDK GUI.  For currently Scripts limitations on Win and Linux OS see: Project Delivery Currently limitations of functionality

  1. _create_win_setup.cmd/_create_linux_setup.sh and follow instructions on shell:
  2. Press 0 and enter to start "Module Selection Guide"
  3. (optional Win OS) Generate Virtual Drive or use short directory  for the reference design (for example x:\<design name>)
  4. Create Project (follow instruction of the product selection guide), settings file will be configured automatically during this process
    1. (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: Select correct one, see also TE Board Part Files
  5. Create XSA and export to prebuilt folder
    1. Run on Vivado TCL: TE::hw_build_design -export_prebuilt
      Note: Script generate design and export files into \prebuilt\hardware\<short dir>. Use GUI is the same, except file export to prebuilt folder
  6. Create Linux (uboot.elf and image.ub) with exported XSA
    1. XSA is exported to "prebuilt\hardware\<short name>"
      Note: HW Export from Vivado GUI create another path as default workspace.
    2. Create Linux images on VM, see PetaLinux KICKstart
      1. Use TE Template from /os/petalinux
  7. Add Linux files (uboot.elf and image.ub) to prebuilt folder
    1. "prebuilt\os\petalinux\<ddr size>" or "prebuilt\os\petalinux\<short name>"
      Notes: Scripts select "prebuilt\os\petalinux\<short name>", if exist, otherwise "prebuilt\os\petalinux\<DDR size>" of the selected device
  8. Generate Programming Files with Vitis
    • Run on Vivado TCL: TE::sw_run_vitis -all
      Note: Depending of PC performance this can take several minutes. Scripts generate applications and bootable files, which are defined in "sw_lib\apps_list.csv" and open Vitis
    • (alternative) Start Vitis with Vivado GUI or start with TE Scripts on Vivado TCL: TE::sw_run_vitis
      Note:  TCL scripts generate also platform project, this must be done manuelly in case GUI is used. See Vitis



Check Module and Carrier TRMs for proper HW configuration before you try any design.

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

Get prebuilt boot binaries

  1. _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
      Note: Folder (<project foler>/_binaries_<Artikel Name>) with subfolder (boot_<app name>) for different applications will be generated


Optional for Boot.bin on QSPI Flash and image.ub on SD.

  1. Connect JTAG and power on carrier with module
  2. Open Vivado Project with "vivado_open_existing_project_guimode.cmd" or if not created, create with "vivado_create_project_guimode.cmd"
  3. Type on Vivado TCL Console: TE::pr_program_flash_binfile -swapp u-boot
    Note: To program with SDK/Vivado GUI, use special FSBL (zynq_fsbl_flash) on setup
             optional "TE::pr_program_flash_binfile -swapp hello_te0720" possible
  4. Copy image.ub on SD-Card
    1. use files from (<project foler>/_binaries_<Articel Name>)/boot_linux from generated binary folder,see: Get prebuilt boot binaries
    2. or use prebuilt file location, see <design_name>/prebuilt/readme_file_location.txt
  5. Insert SD-Card


  1. Copy image.ub and Boot.bin on SD-Card.
    • 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
  2. Set Boot Mode to SD-Boot.
    • Depends on Carrier, see carrier TRM.
  3. Insert SD-Card in SD-Slot.


Not used on this Example.


  1. Prepare HW like described on section TE0720 Test Board#Programming
  2. Connect UART USB (most cases same as JTAG)
  3. Select SD Card as Boot Mode (or QSPI - depending on step 1)
    Note: See TRM of the Carrier, which is used.
  4. Power On PCB
    Note: 1. Zynq Boot ROM loads FSBL from SD into OCM, 2. FSBL loads U-boot from SD into DDR, 3. U-boot load Linux from SD into DDR


  1. Open Serial Console (e.g. putty)
    1. Speed: 115200
    2. COM Port: Win OS, see device manager, Linux OS see  dmesg |grep tty  (UART is *USB1)
  2. Linux Console:
    Note: Wait until Linux boot finished For Linux Login use:
    1. User Name: root
    2. Password: root
  3. You can use Linux shell now.
    1. I2C 0 Bus type: i2cdetect -y -r 0
    2. I2C 1 Bus type: i2cdetect -y -r 1
    3. RTC check: dmesg | grep rtc
    4. ETH0 works with udhcpc
    5. USB: insert USB device
  4. Option Features
    1. Webserver to get access to Zynq
      1. insert IP on web browser to start web interface
    2. init.sh scripts
      1. add init.sh script on SD, content will be load automatically on startup (template included in ./misc/SD)
