Trying to build a Vivado bitstream for the minized+Petalinux

100charlesb

Hi all,

I am trying to find a .bsp file that will create a bitstream to use with PetaLinux.

I tried minzed_ttc_2019_1.bsp

When I open the project I get a number of missing vhdl modules which I found on the Avnet github site.

However I have not been able to find a suitable minized_ttc.xdc constraints file

the minized_petalinux.xdc file I found doesn't work because Vivado finds it impossible to route.

Another issue I have is the block design has locked IP (the PWM module) which means I can't validate the design.

All I am trying to do is to add some I2S support to the minized and I was hoping I could do something like

https://www.hackster.io/news/microzed-chronicles-building-petalinux-for-the-minized-48f79880f849

rather than wade through a load of course material as I have used Petalinux before on a zedboard.

 

I have seen other people on the forum with similar issues but I have either not understood the answers

or the answers were not applicable.

    Hi Charles,

     

    If you are comfortable with git and the Linux command line, you can build a known-good Vivado hardware platform and PetaLinux BSP for MiniZed using the Avnet HDL and PetaLinux git repositories.  These web links provide examples how to do this for the Ultra96-V2 board, but the steps are easily adaptable to the MiniZed.

     

    Avnet HDL git HOWTO (Vivado 2020.1 and earlier)

    Using Avnet Build Scripts to Build a PetaLinux BSP (2019.2 and earlier)

     

    A couple of notes first:

    • The name of the Vivado build script is <>/hdl/Scripts/make_minized_ttc.tcl.
    • The name of the PetaLinux build script is <>/petalinux/scripts/make_minized_ttc_bsp.sh
    • Be sure the hdl and petalinux repositories are both checked out to the version of tools you are using.
      $ git checkout <tools version> (The scripts are current and usable up to 2019.1.  The 2019.2 scripts are being updated/developed now).

     

    Cheers,

    Tom

    Hello Tom,

    Thanks for the very useful reply for a number of reasons (as well as the Minized I also have a Zedboard and a ultra96v1 board).

    I managed to follow those instructions but when I run the make_minized_ttc.tcl Script I get the following

     

    [Vivado 12-172] File or Directory 'E:/VirtualBox_Share/git/avnet/hdl/Projects/minized_ttc/MINIZED_2019_1/../minized_ttc.xdc' does not exist

     

    Which seems to refer to the constrains file I couldn't find before. The bitstream generation obviously fails on the missing constraints

    but at least everything else completes OK.

     

    I am running Vivado in a Windows 10 environment and I have the petalinux tools on a VM running Ubuntu 18.04
