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:

• TE0726 "Test Board" 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/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:

   Code Block
   language bash theme Midnight title _create_win_setup.cmd/_create_linux_setup.sh
   ------------------------Set design paths---------------------------- -- Run Design with: _create_win_setup --

1. 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 (follow instruction 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

     
     

5. 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.

   
   

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

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

     
     

     Page properties
     hidden true id Comments
     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

   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

   
   

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-Boot mode

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

1. Connect JTAG and power module (TE0726 can be powered via JTAG USB or external)
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 -swapp u-boot

   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_te0820 (optional)

   
   

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

   
   

4. 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.
5. 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 (uboot)

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

   Info
   Note: See TRM of the board, which is used.

   
   

   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

   
   

4. Power On PCB

   Expand
   title boot process
   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

   This step depends on Xilinx Device/Hardware for Zynq-7000 series 1. Zynq Boot ROM loads FSBL from SD/QSPI into OCM, 2. FSBL init the PS, programs the PL using the bitstream and loads U-boot from SD/QSPI into DDR, 3. U-boot loads Linux (image.ub) from SD/QSPI/... into DDR for ZynqMP??? 1. ZynqMP Boot ROM loads FSBL from SD/QSPI into OCM, 2. FSBL init the PS, programs the PL using the bitstream and loads PMU, ATF and U-boot from SD/QSPI into DDR, 3. U-boot loads Linux (image.ub) from SD/QSPI/... into DDR for Microblaze 1. FPGA Loads Bitfile from Flash, 2. MCS Firmware configure SI5338 and starts Microblaze, 3. SREC Bootloader from Bitfile Firmware loads U-Boot into DDR (This takes a while), 4. U-boot loads Linux from QSPI Flash into DDR for native FPGA ...

   
   

Linux

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)
      

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

      
      

2. Linux Console:
   

   Code Block
   language bash theme Midnight
   petalinux login: root Password: root

   
   

3. You can use Linux shell now.

   Code Block
   language bash theme Midnight
   i2cdetect -y -r 0 (check I2C 0 Bus) dmesg | grep rtc (RTC check) udhcpc (ETH0 check) lsusb (USB check)
