Reference Design is available on:

• TE0726 "Zynqberry Demo1Demo3" Reference Design

Design Flow

...

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

See also:

• Vivado/SDK/SDSoCAMD 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 be 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 for minimum setupto 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 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  see TE Board Part Files
5. Create HDF 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 (uboot.elf and image.ub) with exported HDFXSA
   
   1. HDF 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
         Note: run init_config.sh before you start petalinux config. This will set correct temporary path variable.
      2. For 128MB and 64MB only:Netboot Offset must be reduced manually, see Config 68616202
7. Add Linux files (uboot.elf and image.ub) to prebuilt folder
   
   1. "prebuilt\os\petalinux\default<DDR size>" or "prebuilt\os\petalinux\<short name>"
      Notes: Scripts select "prebuilt\os\petalinux\<short name>", if exist, otherwise "prebuilt\os\petalinux\default\<DDR size>"
8. Generate Programming Files with HSI/SDKVitis
   
   1. Run on Vivado TCL: TE::sw_run_hsivitis -all
      Note: Scripts generate applications and bootable files, which are defined in "sw_lib\apps_list.csv"
   2. (alternative) Start SDK Vitis with Vivado GUI or start with TE Scripts on Vivado TCL: TE::sw_run_sdkvitis
      Note: See SDK Projects  TCL scripts generate also platform project, this must be done manuelly in case GUI is used. See Vitis

QSPI

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

1. Connect JTAG and power on the carrier with modulemodule (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 _binfile -swapp u-boot
   Note: To program with SDK/Vivado GUI, use special FSBL (zynqmp_fsbl_flash) on setup
            optional "TE::pr_program_flash _binfile -swapp hello_te0726" possible
4. Copy imageBuild Image.ub in Petalinux 
5. Copy the Petalinux image.ub on SD-Card
   • For correct prebuilt file location, see <design_name>/prebuilt/readme_file_location.txt
6. Copy init.sh on SD-Card

...

1. • Location : <design

...

1. • -name>/misc/sd/
2. 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 (u-boot)

...

1. Prepare HW like described in section Programming 68616202
2. Connect UART USB (most cases same as JTAG)
3. Insert SD Card with image.ub
4. Power On PCB
   Note: 1. Zynq Boot ROM loads FSBL from QSPI into OCM, 2. FSBL loads U-boot from QSPI into DDR, 3. U-boot load Linux from SD into DDR

...

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)
2. Linux Console:
   Note: Wait until Linux boot finished For Linux Login use:
   
   1. User Name: root
   2. Password: root
      Note: Wait until Linux boot finished For Linux Login use:
      
      1. User Name: root
      2. Password: root
3. You can use a Linux shell now.
   1. I2C 1 Bus type: i2cdetect -y -r 5
      Bus 0...5 possible
   2. ETH0 works with udhcpc
   3. USB: insert USB device
4. Start Video with "play <video file>"
   1. "play" is alias to ffmpeg with some parameters for video and audio, type "alias" to see configuration
   2. for videos with higher resolution, disable audio on ffmpeg configuration
5. Start Audio with "aplay <audio files>"
6. Take image from camera (must be enabled with init.sh scripts):
   1. write image to webserver: fbgrab -d /dev/fb1 /srv/www/camera.png
   2. Display image on host PC: http://<ZynqBerry IP>/camera.png
   Camera stream will be enabled via init.sh script on SD
