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

Reference Design is available on:

• TE0710 "Test Board" Reference Design

Design Flow

Trenz Electronic provides a tcl based built environment based on AMD Design Flow.

See also:

• Xilinx 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 AMD 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:

   _create_win_setup.cmd/_create_linux_setup.sh

   ------------------------Set design paths----------------------------
   -- Run Design with: _create_win_setup

   -- (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 AMD 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.

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

   • 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 and image.ub 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

9. (Optional) BlockRam Firmware Update

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

   2. Regenerate Vivado Project or Update Bitfile only with "spi_bootloader.elf"

      TE::hw_build_design -export_prebuilt
      TE::sw_run_vitis -all

Launch

Programming

AMD 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

Option for u-boot.mcs on QSPI Flash.
(u-boot.mcs contains all files necessary to boot up linux)

1. Connect the USB cable(JTAG) and power supply 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"

   run on Vivado TCL (Script programs BOOT.bin on QSPI flash)

   TE::pr_program_flash -swapp u-boot

3. Reboot (if not done automatically)

SD-Boot mode

Not used on this Example.

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 as Boot Mode (or QSPI - depending on step 1)

   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

   boot process

   1. FPGA Loads Bitfile from Flash,

   2. SPI Bootloader from Bitfile Firmware loads U-Boot into DDR (This takes a while)

   
   

   3. U-boot loads Linux from QSPI Flash into DDR

Linux

1. Open Serial Console (e.g. putty)
   
   • Speed: 9600

   • select COM Port

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

2. Linux Console:
   

   root@petalinux:

   Note: Wait until Linux boot finished, autologin is activated.
   

3. You can use Linux shell now.
