Reference Design is only usable with the specified Vivado/Vitis/PetaLinux version. Do never use different Versions of AMD(Xilinx) Software for the same Project.

Reference Design is available on:

• TE0712 "Test Board" Reference Design

Design Flow

See also: AMD Development Tools#XilinxSoftware-BasicUserGuides

• 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/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. (optional Win OS) Generate Virtual Drive or use short directory  for the reference design (for example x:\<design name>)
4. 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 AMD(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.

   • Thepetalinux build images are located in the "<plnx-proj-root>/images/linux" directory
     

     Info
     Important Note: Select correct Flash partition offset on petalinux-config: Subsystem Auto HW Settings → Settings → Flash Settings,  FPGA+Boot+bootenv=0x900000 0xA00000 (increase automatically generate Boot partition), increase image size to A:, see Config

     
     

      

7. Configure the boot.scr file as needed, see Distro Boot with Boot.scr. Kernel flash address and kernel size are set here.
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>"

     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

   
   

10. (Optional) BlockRam Firmware Update

    1. Copy "<project folder>\prebuilt\software\<short name>\spi_bootloader.elf" into  "<project folder>\firmware\microblaze_0\"

    2. Copy "<project folder>\workspace\sdk\scu_te0712\Release\scu_te0712.elf" into "\firmware\microblaze_mcs_0\"

    3. Regenerate Vivado Project or Update Bitfile only with "spi_bootloader.elf" and "scu_te0712.elf"

       Code Block
       language bash theme Midnight
       TE::hw_build_design -export_prebuilt TE::sw_run_vitis -all

Software Design - Vitis

For Vitis project creation, follow instructions from:

Vitis

Application

Template location: "<project folder>\sw_lib\sw_apps\"

scu_te0712

MCS Firmware to configure SI5338 and Reset System.

spi_bootloader

TE modified SPI Bootloader from Henrik Brix Andersen.

Bootloader to load app or second bootloader from flash into DDR.

Here it loads the u-boot.elf from QSPI-Flash to RAM. Hence u-boot.srec becomes redundant.

Descriptions:

• Modified Files: bootloader.c
• Changes:
  
  • Change the SPI defines in the header
  • Add some reiteration in the frist spi read call

hello_te0712

Hello TE0712 is a AMD(Xilinx) Hello World example as endless loop instead of one console output.

u-boot

U-Boot.elf is generated with PetaLinux. Vitis is used to generate u-boot.srec(obsolete). Vivado to generate *.mcs

eeprom is a petalinux application that executes on startup. It reads the unique 48-bit MAC from the onboard eeprom and uses it to set the system MAC address.

Software Design -  PetaLinux

For PetaLinux installation and project creation, follow instructions from:

• PetaLinux KICKstart
