How to create Ultra96v2 Linux-based Platform in Xilinx Vitis 2020.1

Creating the Ulra96v2 platform in the Xilinx Vitis has four steps:

  1. XSA design – Generating a Vivado project containing the underlying hardware
  2. Linux OS – Generating a PetaLinux project to configure Linux
  3. Create Platform – Using Xilinx Vitis to generate the Platform
  4. Test– Create a simple application to test the generated platform

In the sequel, I am trying to briefly explain each step. I have installed Xilinx Vitis and Petalinux 2019.2 under the Ubuntu 18.04 OS. Note that, the Xilinx Vitis software includes Vivado, so you do not need to install that separately.

To make Vivado detects the board, copy the Avnet ultra96v2 board definition files (at here) to the <Vivado installation folder>/data/boards/board_files.

1- XSA design

1- create a directory called ultra96v2-vitis-pkg

mkdir ultra96v2-vitis-pkg
cd ultra96v2-vitis-pkg/

2- create a director called vivado

mkdir vivado 
cd vivado

3- Run Vivado and create a project called ultra96v2-xsa in the ultra96v2-vitis-pkg/vivado folder. Figures 1-6 show the flow of the project creation.

Figure 1
Figure 2
Figure 3
Figure 4
Figure 5
Figure 6

4- In the Vivado project, create a block design with the name of ultra96v2_design.

Figure 7

5- Add a Zynq UltraScale+ MPSoC IP into the Diagram view

Figure 8

6- Click on “Run Block Automation” and make sure “Apply Board Reset” is selected.

Figure 9

7- Double click on the Zynq IP and configure that as Figure 10

Figure 10

8- Add a Clocking Wizard IP to the design.

Figure 11

9- Double click on the added IP and configure that as Figure 12. Add four output clocks with different output frequencies, and make sure that the reset type is “Active Low”.

Figure 12

10- Add four Processor System Reset IPs corresponding to the four output clocks.

Figure 13

11- Add connections as Figure 14.

Figure 14

12- Add a Concat IP

Figure 15

13- Configure the added IP as Figure 16 and connect that to the Zynq as shown in Figure 7.

Figure 16
Figure 17

14- Now, we should declare the platform (PFM) interface and properties. For this purpose, select “Platform Interfaces” option from the “Window” menu in the Vivado IDE. (Window–>Platform Interfaces).

15- Click on “Enable platform interfaces” if this the first time you select the Platform Interfaces option in the project.

16- Right-click on each option and select Enable to enable the following interfaces:

17- Select S_AXI_HPC0_FPD port and write HPC0 in the sptag under Option in Platform Interface Properties pannel. For other ports do similar setting
S_AXI_HP0_FPD ---> HP0
S_AXI_HP1_FPD ---> HP1
S_AXI_HP2_FPD ---> HP2
S_AXI_HP3_FPD ---> HP3

Note, to change the sptag filed you must press the Enter key on your keyboard. So, don't forget to press Enter each time.

18- Enable the following clock interfaces


19- Select the enabled clk_out1 and in the Options window change the id to 0 and select the is_default. Note, to change the id filed you must press the Enter key on your keyboard. Change ids of clk_out2, clk_out3, and clk_out4 to 1, 2, and 3, respectively.

20- In the xlconcat_0 interfaces, enable In0, Int1, Int2, Int3, Int4, Int5, Int6, Int7, which are interrupt interfaces.

21- Go to the “TCL Console” view and run these commands

set_property platform.design_intent.embedded true [current_project]
set_property platform.design_intent.server_managed false [current_project]
set_property platform.design_intent.external_host false [current_project]
set_property platform.design_intent.datacenter false [current_project]
set_property platform.default_output_type "sd_card" [current_project]

22- Press the right-click in Diagram view and in the popup menu select Validate Design.

23- Press the right-click on the “ultra96v2_design (” option in the source view panel. And from the popup menu select “Generate Output Products…”.

24- Select the Generate button and wait for the process to finish.

25- Again, press the right-click on the “ultra96v2_design (” option in the source view panel. And from the popup menu select “Create HDL Wrapper… ” and select the “Let Viviado manage wrapper and auto-update” option in the dialog box.

26- Then under the PROGRAM AND DEBUG option in the left-hand side panel, select “Generate Bitstream” and wait until the end of the process.

27- After generating the bitstream, go to the TCL Console view and make sure you are in the right folder. you can use pwd command to check the folder. Go to “ultra96v2-vitis-pkg/vivado” that you have created. and run the following TCL command to generate the XSA file

write_hw_platform -include_bit ultra96v2.xsa

28- You can validate the generated XSA file by running the following TCL command.

validate_hw_platform ./ultra96v2.xsa

2- Linux OS

1- Go to the “ultra96v2-vitis-pkg” folder generated in the first step (i.e., 1-XSA design) and run the followoing commands

mkdir linux_files
mkdir  linux_files/boot

2- Run the file located at the PetaLinux installation folder by running this command

source /home/opt/petalinux/2019.2/

3- In the “ultra96v2-vitis-pkg” folder create a PetaLinux project

petalinux-create -t project --template zynqMP -n ultra96v2-petalinux

4- Go to the generated project folder and configure the project

cd ultra96v2-petalinux
petalinux-config --get-hw-description=../vivado

5- In the “misc/config System Configuration” window, go to “Subsystem AUTO Hardware Settings–>Serial Setting” and change the “psu_uart_0” to “psu_uart_1” and back to the main menu.

5- In the “DTG Settings –>Kernel Bootargs–>” disable generate boot args automatically” option. then in the “user set kernel bootargs” enter the following arguments

earlycon clk_ignore_unused root=/dev/ram rw

  1. Hi,
    Thanks a lot for the tutorial, but where can i find the description of these steps, i would like to understand all the steps I am following
    Best Reh

      1. Can I follow the exact same steps including editing the device tree with the same values you have given for the ZCU102 board? Or I should change something?

  2. I followed the exact same steps but i got the following error when i tied building the petalinux :

    1. It seems you have mistakes (typos) at line 6 in system-user.dtsi file.
      check for semicolons, parenthesis
      and remember to only add the following code at the end of the file

      &amba {

      Debe verificar que tenga los drivers open cl y el runtime XIlinx instalados. (

      Luego, en el paso 7 de la sección 4-Test del tutorial, debe verificar que lo realice de la forma correcta. Dar build ubicado correctamente sobre el archivo que muestra la figura.

  3. Using Ubuntu 16.04 and followed your steps still to “write_hw_platform -include_bit ultra96v2.xsa”, then I got a Warning and error message.

    “WARNING: [Project 1-971] Hardware Platform (Shell) metadata attributes vendor, board, name, version will be populated from project properties platform.vendor (xilinx), platform.board_id (ultra96), () and platform.version (0.0). The values from PFM_NAME property (vendor:lib:ultra96v2_design:1.0) on the BD will be over-ridden.

    ERROR: [Common 17-53] User Exception: Project property needs to be set before generating a XSA.”

    1. I found am alternative way, use the GUI and export the hardware and select the include bitstream instead of the command.

  4. I followed this process and I could compile the vadd example. However, when I turned the board ON, D8 LED on the mezzanine board is blinking and the board is not booting up. I have another image with which the board is booting up and D8 is also not blinking.

  5. Hi Mohammad, thank you for your article, it’s really useful for me.
    May I know what does zyxclmm_drm refer to in the device tree part?
    I created a module at the same address at 0xA0000000, and I am learning how to write the device into the device tree, so I am curious about this.
    Thank you in advance.

      1. Thank you very much for your kind reply and I am really thankful for your sharing!

  6. Hi Mohammad,
    thank you for your step by step tutorial. It’s really useful for me. I followed the exact the same steps but I was not able to run linux on my device. It looks like it got stuck in boot.

    What can cause this error?

    Thank you for your attention,


      1. If I create SD from demo provided by Avnet then board starts and works correctly but if I try to build the image by myself it doesn’t.

      2. It looks like zynqmp_fsbl.elf is incorrectly generated from zynqmp template. I replaced it with the zynqmp_fsbl.elf file which was generated from ultra96v2_oob_2019_2.bsp and everything works. The question is why the zynqmp_fsbl.elf file from template was incorrectly generated by petalinux and how to fix it.

  7. Thank you Mohammad for posting this detailed step-by-step tutorial. I am using version 2020.1 of Petalinux and have encountered two problems, one solved and one that led to failure:

    → step 8: DMA size is not in Driver Options but in Library Routines -> DMA Contiguous Memory Allocator (256 to be changed to 1024). This seems OK.

    → step 14: petalinux-build has one error related to a python call: here is the log:

    ERROR: libmali-xlnx-r9p0-01rel0-r0 do_package: Error executing a python function in exec_python_func() autogenerated:

    The stack trace of python calls that resulted in this exception/failure was:

    Would you please comment as I couldn’t find a solution? I’d really appreciate!

  8. Problem solved by itself: I had to run petalinux-build again and again: each time a new error appeared, which was solved by the next attempt until all errors disappeared, Go figure…

  9. New problem, not solved this time: when I run the script (step 16) I get this message:

    SDK could not be set up. Relocate script unable to find Abort!

    I think it might have to do with the “/lib” directory, because this is where the script is looking for the library while I guess it has to be somewhere in the sysroot directory. This is a snippet of what I get when I run “sh -x ./”

    + real_env_setup_script=
    ++ ls /home/casu/testvitis/ultra96v2-vitis-pkg/linux_files/environment-setup-aarch64-xilinx-linux
    + for env_setup_script in ‘`ls $target_sdk_dir/environment-setup-*`’
    + grep -q OECORE_NATIVE_SYSROOT= /home/casu/testvitis/ultra96v2-vitis-pkg/linux_files/environment-setup-aarch64-xilinx-linux
    + sed -e s:/opt/petalinux/2020.1:/home/casu/testvitis/ultra96v2-vitis-pkg/linux_files:g -i /home/casu/testvitis/ultra96v2-vitis-pkg/linux_files/environment-setup-aa
    + ‘[‘ -n ” ‘]’
    + xargs –version
    ++ cat /home/casu/testvitis/ultra96v2-vitis-pkg/linux_files/environment-setup-aarch64-xilinx-linux
    ++ cut -d= -f2
    ++ tr -d ‘”‘
    + native_sysroot=
    ++ find /lib -name ‘ld-linux*’
    + dl_path=
    + ‘[‘ ” = ” ‘]’
    + echo ‘SDK could not be set up. Relocate script unable to find Abort!’
    + exit 1

    Any suggestions?

    Thanks a lot

  10. For whom may get the same issue.

    I had an issue with step 5 and I fixed it with the following:

    5- In the “DTG Settings –>Kernel Bootargs–>” disable generate boot args automatically” option. then in the “user set kernel bootargs” enter the following arguments

    (earlycon clk_ignore_unused root=/dev/ram rw) ==> Didn’t work for me
    earlycon clk_ignore_unused console=ttyPS0,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait) ==> Worked for me
