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:

Design Flow


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

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

Caution! Win OS has a 260 character limit for path lengths which can affect the Vivado tools. To avoid this issue, use Virtual Drive or the shortest possible names and directory locations for the reference design (for example "x:\<project folder>")

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

    _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. 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

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

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

    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

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

  7. 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>"

  8. Generate Programming Files with Vitis

    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)

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

Launch


Programming

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

Reference Design is also available with prebuilt files. It's recommended to use TE prebuilt files for first launch.

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

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

QSPI-Boot mode

Boot.bin on QSPI Flash and image.ub and boot.scr on SD.

  1. Connect USB Power In to get power on module
  2. Open Vivado Project with "vivado_open_existing_project_guimode.cmd" or if not created, create with "vivado_create_project_guimode.cmd"

  3. run on Vivado TCL (Script programs BOOT.bin on QSPI flash)
    TE::pr_program_flash -swapp u-boot
    TE::pr_program_flash -swapp hello_te0727 (optional)

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

  4. Remove cable from USB Power In
  5. Copy image.ub and boot.scr 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"
    • Important: Do not copy Boot.bin on SD (it is not used; see SD note), only other files.
  6. Copy init.sh on SD
    • location: <project folder>/misc/sd/
  7. Insert SD-Card in SD-Slot.
  8. Connect USB Power In to get power on module

SD-Boot mode

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

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. Insert SD Card with image.ub and boot.src

    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. Zynq Boot ROM loads FSBL from QSPI into OCM,

    2. FSBL init PS, programs PL using the bitstream and loads U-boot from QSPI into DDR,

    3. U-boot loads Linux (image.ub) from SD/QSPI/... into DDR


Linux

  1. Open Serial Console (e.g. putty)
    • Speed: 115200
    • 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 1 Bus)
    lsusb     			(USB check)
  4. Option Features

    • init.sh scripts
      • add init.sh script on SD, content will be load automatically on startup (template included in "<project folder>\misc\SD")
