Reference Design is only usable with the specified Libero/SoftConsole version. Do never use different versions of Microsemi Software for the same Project.

Reference Design is available on:

• TEM0002 "Webserver Demo" Reference Design    <<================ ADD / Convert to - LINK

Preparations

The reference design is available as a prebuild zip archieve, which contains the hard & soft -ware project folders and the board configuration file "microsemi-smartfusion2-smartberry-ddr.cfg" . It was created and tested in windows environment.

The zip archieve must to be extracted. The board configuration file needs to copied into your SoftConsole installation directory. When taking the required SoftConsole version into account, SoftConsole version 6.2, and the default installation path, copy the board configuration file into:
"C:\Microsemi\SoftConsole_v6.2\openocd\share\openocd\scripts\board\"

Connecet the board via usb cable to your demo host computer.

Check the usb driver installation

Connect the boards ethernet port to your demo host computer. The demo is confiured to establish a network connection via the DHCP protocol, therefore a free router / network port can be used.
A direct port to port connection between the demo host computer and the board is also possible but requires to reconfigure the software project.

Hardware design flashing

Open Libero 12.4, in the to left corner, open the demo hardware project via   "Project > Open Project" and point to file dialog to the demo archieves hardware project dicsk:\Path_to_the_hardware_project_inside_the_archieve\ , double left mouse click onto the project file "Smartberry_Webserver.prjx" to open it.

The board is automatically selected and setup to be flashed by Libero.

In the upper left section of Libero, select the tab "Design Flow" and flash it to the board via   "Program Design > and double left mouse click onto   Run PROGRAM Action".

The hardware design is volatile and therefor lost when powering the board down.

Design Flow

Trenz Electronic provides a tcl based built environment based on Xilinx 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 Xilinx Vivado/SDK GUI.  For currently Scripts limitations on Win and Linux OS see: Project Delivery Currently limitations of functionality

1. _create_win_setup.cmd/_create_linux_setup.sh and follow instructions on shell:
   
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)
   
   1. (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 alsoTE Board Part Files
      1. Important: Use Board Part Files, which ends with *_tebf0808
5. Create XSA and export to prebuilt folder
   
   1. Run on Vivado TCL: TE::hw_build_design -export_prebuilt
      Note: Script generate design and export files into \prebuilt\hardware\<short dir>. Use GUI is the same, except file export to prebuilt folder
6. Create Linux (bl31.elf, uboot.elf , Image and system.dtb) with exported XSA
   
   1. XSA is exported to "prebuilt\hardware\<short name>"
      Note: HW Export from Vivado GUI create another path as default workspace.
   2. Create Linux images on VM, see PetaLinux KICKstart
      1. Use TE Template from /os/petalinux/
      2. Execute the script file for Debian/Ubuntu
7. Add Linux files (bl31.elf, uboot.elf , Image and system.dtb) to prebuilt folder
   
   1. "prebuilt\os\petalinux\<ddr size>" or "prebuilt\os\petalinux\<short name>"
8. Generate Programming Files with Vitis
   
   1. Run on Vivado TCL: TE::sw_run_vitis -all
      Note: Scripts generate applications and bootable files, which are defined in "sw_lib\apps_list.csv"
   2. (alternative) Start SDK with Vivado GUI or start with TE Scripts on Vivado TCL: TE::sw_run_vitis
      Note:  TCL scripts generate also platform project, this must be done manuelly in case GUI is used. See Vitis
9. Preparing SD card for SD Filesystem and hard disk for HD Filesystem → See Programming section

Launch

For basic board setup, LEDs... see: TEBF0808 Getting Started

Programming

Xilinx documentation for programming and debugging: Vivado/SDK/SDSoC-Xilinx Software Programming and Debugging

Get prebuilt boot binaries

1. _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 foler>/_binaries_<Artikel Name>) with subfolder (boot_<app name>) for different applications will be generated

QSPI

Not used in this example.

SD

1. Format the SD Card with SD Card Formatter or other tool
2. Write the Debian image or Ubuntu image file on SD Card with Win32DiskImager
3. It will automatically in BOOT directory two DTB file generated
   1. system_sd.dtb : This file ist used , if the root file system is located on SD card.
   2. system_harddisk.dtb : This file ist used , if the root file system is located on hard disk.
   3. Note: To use one of the DTB files, this file must be renamed to system.dtb
4. Rename the system_sd.dtb file in BOOT directory to system.dtb
5. Copy Petalinux  Image (not use image.ub), system.dtb and Boot.bin files on SD-Card.
   • 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
6. Set Boot Mode to SD-Boot.
   • Depends on Carrier, see carrier TRM.
7. Insert SD-Card in SD-Slot.

JTAG

Not used on this Example.

Usage

1. Prepare HW like described on section TE0808 StarterKit#Programming
2. Connect UART USB (JTAG XMOD)
3. Select SD Card as Boot Mode (or QSPI - depending on step 1)
   Note: See TRM of the Carrier, which is used.
