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:

• TE0720 "Test Board" Reference Design

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

     
     

4. 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.

   
   

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
     

     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 ... ...

     
     

8. 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

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 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 BOOT.bin on QSPI flash)
   TE::pr_program_flash -swapp u-boot TE::pr_program_flash -swapp hello_te0720 (optional)

   
   

   Note
   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

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 68616214
2. Connect UART USB (most cases same as JTAG)

3. Select SD Card as Boot Mode (or QSPI - depending on step 1)

   Info
   Note: See TRM of the Carrier, 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 SD/QSPI 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

   • select COM Port

     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

   
   

   Info
   Note: Wait until Linux boot finished

   
   

3. You can use Linux shell now.
   

   Code Block
   language bash theme Midnight
   i2cdetect -y -r 0 (check I2C 0 Bus) i2cdetect -y -r 1 (check I2C 1 Bus) dmesg | grep rtc (RTC check) udhcpc (ETH0 check) lsusb (USB check)

   
   

4. Option Features
   • Webserver to get access to Zynq
