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:

• TE0821 "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/SDK 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:

   ------------------------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. (optional Win OS) Generate Virtual Drive or use short directory  for the reference design (for example x:\<design name>)
4. Create project 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: Select correct one, see also Vivado Board Part Flow

     
     

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

   TE::hw_build_design -export_prebuilt

   
   

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

   
   

6. 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

7. Configure the boot.scr file as needed, see Distro Boot with Boot.scr
8. 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
     

     "<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, image.ub and boot.scr from "<plnx-proj-root>/images/linux" to prebuilt folder for ZynqMP copy u-boot.elf, bl31.elf, image.ub and boot.scr from "<plnx-proj-root>/images/linux" to prebuilt folder for ... ...

     
     

9. Generate Programming Files with Vitis

   TE::sw_run_vitis -all TE::sw_run_vitis (optional; Start Vitis from Vivado GUI or start with TE Scripts on Vivado TCL)

   
   

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

   
   

Launch

Programming

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

Note: Depending on CPLD Firmware and Boot Mode settings, QSPI boot with Linux image on SD or complete SD Boot is possible.

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

      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 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"

   TE::pr_program_flash -swapp u-boot TE::pr_program_flash -swapp hello_te0821 (optional)

   
   

   To program with Vitis/Vivado GUI, use special FSBL (fsbl_flash) on setup

   
   

3. Copy image.ub and boot.scr on SD or USB
   
   • use files from "<project folder>\_binaries_<Article Name>\boot_linux" from generated binary folder,see: Get prebuilt boot binaries
   • or use prebuilt file location, see "<project folder>\prebuilt\file_location.txt"
4. Set Boot Mode to QSPI-Boot and insert SD or USB.
   • Depends on Carrier, see carrier TRM.

SD-Boot mode

Use this description for CPLD Firmware with SD Boot selectable.

1. Copy image.ub, boot.src and Boot.bin on SD
   
   • use files from "<project folder>\_binaries_<Article Name>\boot_linux" from generated binary folder, see: Get prebuilt boot binaries
   • or use prebuilt file location, see "<project folder>\prebuilt\file_location.txt"
2. Set Boot Mode to SD-Boot.
   • Depends on Carrier, see carrier TRM.
3. Insert SD-Card in SD-Slot.

JTAG

Not used on this Example.

Usage

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

3. Select SD Card or QSPI as Boot Mode (Depends on used programming variant)

   Note: See TRM of the Carrier, which is used.

   
   

   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

   
   

4. Power On PCB

   1. ZynqMP Boot ROM loads PMU Firmware and  FSBL from SD/QSPI Flash into OCM 2. FSBL init PS, programs PL using the bitstream and loads U-boot from SD into DDR, 3. U-boot loads Linux (image.ub) from SD/QSPI/... into DDR

   
   

Linux

1. Open Serial Console (e.g. putty)
   
   1. Speed: 115200

   2. Select COM Port
      
      

      Win OS, see device manager, Linux OS see dmesg |grep tty (UART is *USB1)

      
      

2. Linux Console:
   

   petalinux login: root Password: root

   
   

   Note: Wait until Linux boot finished

   
   

3. You can use Linux shell now.
   
   

   i2cdetect -y -r 0 (check I2C 0 Bus) dmesg | grep rtc (RTC check) udhcpc (ETH0 check) lsusb (USB check)

   
   

4. Option Features
   • Webserver to get access to Zynq
     • insert IP on web browser to start web interface
   • init.sh scripts
     • add init.sh script on SD, content will be load automatically on startup (template included in ./misc/SD)
   
   

Vivado HW Manager

Monitoring:

• SI5338_CLK0 Counter: 
  
  • Open Vivado HW-Manager and add VIO signal to dashboard (*.ltx located on prebuilt folder).
    • Set radix from VIO signals to unsigned integer.
      Note: Frequency Counter is inaccurate and displayed unit is Hz for CLK signals
• SI5338 CLK1 is configured to  200MHz by default amd SI5338 CLK3 is configured to 125MHz by default.

Control:

• Simple loopback vio_test_in test_out
• LED over X0/X1 , see TE0821 CPLD#LED
