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:

• TE0725LP "Test Board" Reference Design

Design Flow

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

See also:

• Xilinx Development Tools
• 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
   ------------------------Set design paths---------------------------- -- Run Design with: _create_win_setup -- Use Design Path: <absolute project path> -------------------------------------------------------------------- -------------------------TE Reference Design--------------------------- -------------------------------------------------------------------- -- (0) Module selection guide, project creation...prebuilt export... -- (1) Create minimum setup of CMD-Files and exit Batch -- (2) Create maximum setup of CMD-Files and exit Batch -- (3) (internal only) Dev -- (4) (internal only) Prod -- (c) Go to CMD-File Generation (Manual setup) -- (d) Go to Documentation (Web Documentation) -- (g) Install Board Files from Xilinx Board Store (beta) -- (a) Start design with unsupported Vivado Version (beta) -- (x) Exit Batch (nothing is done!) ---- Select (ex.:'0' for module selection guide):

   
   

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

     1. 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.

        
        

4. 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)

   
   

   Info
   Note: Scripts generate applications and bootable files, which are defined in "sw_lib\apps_list.csv" App from Firmware folder will be add into BlockRAM. If you add other app, you must select *.elf manually on Vivado

   
   

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

   
   

5. (optional) Copy Application (hello_te0725.elf) from prebuilt-folder into \firmware\microblaze_0\ and regenerate design with

   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

   
   

Launch

Programming

Xilinx documentation for programming and debugging: Vivado/SDK/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

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"

   
   

   Code Block
   language py theme Midnight title run on Vivado TCL (Script programs .mcs-File on QSPI flash)
   TE::pr_program_flash -swapp hello_te0725

   
   

3. Press the reset button to start the application and see the output in the console

SD

Not used on this Example.

JTAG

1. Connect JTAG and power on PCB
2. Open Vivado HW Manager
3. Program FPGA with Bitfile from "prebuilt\hardware\<short dir>\"

Usage

1. Prepare HW like described on section Programming
2. Connect UART USB (most cases same as JTAG)

3. 
   

   Expand
   title boot process
   1. FPGA Loads Bitfile from Flash 3. Hello Trenz will be run on UART console.   info: Do not reboot, if Bitfile programming over JTAG is used as programming method. UART Open Serial Console (e.g. putty) Hello TE0725 will run on endless loop. Speed: 9600 COM Port: Win OS, see device manager, Linux OS see  dmesg |grep tty  (UART is *USB1) Image Added Power On PCB (Do not restart, if you use Bitfile programming)
