Design supports following carriers:

Design Sources

...

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 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:
   Image RemovedImage Added
2. Press 0 and enter for minimum setup
3. (optional Win OS) Generate Virtual Drive or use short directory  for the reference design (for example x:\<design name>)
4. Create Project
   
   1. 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 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 HDF
   
   1. HDF 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.
7. Add Linux files (uboot.elf and image.ub) to prebuilt folder
   
   1. "prebuilt\os\petalinux\default" or "prebuilt\os\petalinux\<short name>"
      Notes: Scripts select "prebuilt\os\petalinux\<short name>", if exist, otherwise "prebuilt\os\petalinux\default"
8. Generate Programming Files with HSI/SDK
   
   1. Run on Vivado TCL: TE::sw_run_hsi
      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_sdk
      Note: See SDK Projects

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

QSPI

Optional for Boot.bin on QSPI Flash and image.ub on SD.

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"
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 setupCopy image.ub on

SD

...

• For correct prebuilt file location, see <design_name>/prebuilt/readme_file_location.txt

...

Not used on this Example.

JTAG

Not used on this Example.

SD

1. Copy image.ub and Boot.bin on SD-Card.
   • For correct prebuilt file location, see <design_name>/prebuilt/readme_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 Programming
2. Connect UART USB (most cases same as JTAG)
3. Select SD Card QSPI as Boot Mode
   Note: See TRM of the Carrier, which is used.
4. Power On PCB
   Note: 1. Zynq Boot ROM loads FSBL from SD QSPI into OCM, 2. FSBL initialised SI5338 and loads U-boot from SD QSPI into DDR, 3. U-boot load Linux from SD QSPI into DDR

Linux

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
3. You can use Linux shell now.
   1. I2C 0 Bus type: i2cdetect -y -r 0
   2. RTC check: dmesg | grep rtc
   3. ETH0 works with udhcpc
   4. USB type  "lsusb" or connect USB2.0 device

Vivado Vivado HW Manager

SI5338 _CLK0 CounterMGT Reference CLKs: 

• Open Vivado HW-Manager and add VIO signal to dashboard (*.ltx located on prebuilt folder).
• Set radix from VIO signals to unsigned integer.
  Note: Frequency Counter is inaccurate and displayed unit is Hz

System Design - Vivado

• SI5338 CLKs are configured to 125MHz with example FSBL initialisation.

PL MIG Status Status signal:

• Status signals connected to VIO

Image Added

Custom LED

Red LED D1 can be controlled via VIO.

RGPIO

RGPIO Pins can be controlled via VIO
