Reference Design is only usable with the specified Vivado/Vitis/PetaLinux version. Do never use different Versions of Xilinx Software for the same Project.
Reference Design is available on:
Reference Design is available with and without prebuilt files. It's recommended to use TE prebuilt files for first launch.
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
Caution! Win OS has a 260 character limit for path lengths which can affect the Vivado tools. To avoid this issue, use Virtual Drive or the shortest possible names and directory locations for the reference design (for example "x:\<project folder>")
Run _create_win_setup.cmd/_create_linux_setup.sh and follow instructions on shell:
Press 0 and enter to start "Module Selection Guide"
- 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 Xilinx 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
Create hardware description file (.xsa file) for PetaLinux project and export to prebuilt folder
Using Vivado GUI is the same, except file export to prebuilt folder.
- Create and configure your PetaLinux project with exported .xsa-file, see PetaLinux KICKstart
build images are located in the "<plnx-proj-root>/images/linux" directory
Configure the boot.scr file as needed, see Distro Boot with Boot.scr
- 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
"prebuilt\os\petalinux\<ddr size>" or " \prebuilt\os\petalinux\<short name>"
Generate Programming Files with Vitis
TCL scripts generate also platform project, this must be done manually in case GUI is used. See Vitis
Check Module and Carrier TRMs for proper HW configuration before you try any design.
Reference Design is also available with prebuilt files. It's recommended to use TE prebuilt files for first launch.
Get prebuilt boot binaries
- Run _create_win_setup.cmd/_create_linux_setup.sh and follow instructions on shell
- Press 0 and enter to start "Module Selection Guide"
- Select assembly version
- Validate selection
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
Boot.bin on QSPI Flash and image.ub and boot.scr on SD.
- Connect USB Power In to get power on module
Open Vivado Project with "vivado_open_existing_project_guimode.cmd" or if not created, create with "vivado_create_project_guimode.cmd"
To program with Vitis/Vivado GUI, use special FSBL (fsbl_flash) on setup
- Remove cable from USB Power In
- Copy image.ub and boot.scr on SD
- use files from "<project folder>\_binaries_<Article Name>\boot_linux" from generated binary folder,see: Get prebuilt boot binaries
- or use prebuilt file location, see "<project folder>\prebuilt\file_location.txt"
- Important: Do not copy Boot.bin on SD (it is not used; see SD note), only other files.
- Copy init.sh on SD
- location: <project folder>/misc/sd/
- Insert SD-Card in SD-Slot.
- Connect USB Power In to get power on module
Xilinx Zynq devices in CLG225 package do not support SD Card boot directly from ROM bootloader. Use QSPI for primary boot (fsbl, u-boot) and SD for secondary boot (image.ub, boot.src)
Not used on this Example.
Prepare HW like described in section Programming
Connect UART USB (most cases same as JTAG)
Insert SD Card with image.ub and boot.src
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
Power On PCBboot process
1. Zynq Boot ROM loads FSBL from QSPI into OCM,
2. FSBL init PS, programs PL using the bitstream and loads U-boot from QSPI into DDR,
3. U-boot loads Linux (image.ub) from SD/QSPI/... into DDR
Open Serial Console (e.g. putty)
select COM Port
Win OS, see device manager, Linux OS see dmesg |grep tty (UART is *USB1)
Note: Wait until Linux boot finished
You can use Linux shell now.
Camera stream will be enabled via init.sh script on SD
Take image from camera (must be enabled with init.sh script):
