MiniZed Petalinux 2010.1

bigguiness

Hello all,

 

I'm following this, Minized getting started 2020.1 + PYNQ setup , to try and figure out the Petalinux 2010.1 workflow with a MiniZed board.

 

During the "Building project..." stage I got a WARNING and ERROR about speexdsp-1.2rc3-r0 not being found.

 

After quite a while (where I assume it was building the packages) I got this:

 

NOTE: Tasks Summary: Attempted 4686 tasks of which 3322 didn't need to be rerun and all succeeded.

 

Summary: There was 1 WARNING message shown.

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

ERROR: Failed to build avnet-image-full

 

It's still building but I was wondering how I can fix the WARNING/ERROR and how do you do a rebuild without going through the initial part that builds seems to build the Vivado part?

 

Thanks

  • Well.. the build appears to be stuck here:

    It's been at 89% for about an hour. I'm leaving it running for now to see if it ever finishes.

     

    Any ideas...

  • Hi Hartley,

     

    You are correct that the MiniZed BSP build script also builds the underlying hw platform in Vivado.  The build script senses if the hw project has been built and runs Vivado in the background to build it.  This also means that the hw project only has to be built once.  The next time the BSP build script is run it will just grab the Vivado xsa and bitstream files and import them into the PetaLinux project.  This saves significant time.

     

    A PetaLinux build requires an active internet connection, and the "ERROR about speexdsp-1.2rc3-r0 not being found" error you mention could be the result of a few things:

    • Your internet connection having problems
    • The server where the speexdsp package is hosted is having internet connection problems
    • The speexdsp package files have moved to a different server, or the version has changed, but the package build recipe has not be updated

     

    Sometimes this warning/error will fix itself on a retry of the build.  Quite often this error will fix itself (e.g. the package recipe will find alternate hosting sites for the package sources) while the BSP is being built.

    It appears the build task it is stuck is on compiling the kernel.  Depending on your PC resources (RAM, CPU cores, etc.) it can take a long time to complete some build tasks like compiling the kernel.

    Should I just kill the build and run the ./make_minized.sh script again?

  • in reply to bigguiness

    Killing the PetaLinux build is sometimes tricky.  It does not like to be killed and will often hang.  If you do that you should reboot to be sure there aren't any stray processes still running.

    Hmmm. A Ctrl-C didn't kill the build. It appears to have restarted it.

     

    Looking at the log it looks like it has restarted a couple times. Is this normal?

  • in reply to bigguiness

    The ./make_minized.sh script finally finished but I did a Ctrl+C a number of times when it appeared to hang while compiling the kernel. Not sure what effect that will have.

     

    I think running the script again and just letting it try to finish overnight may be worthwhile. What is the best way to ensure that the build is clean?

  • in reply to bigguiness

    The best way to do a clean and rebuild is the following concatenated (&&) commands:

    $ petalinux-build -x mrproper --force && petalinux-build

  • in reply to bigguiness

    The BSP build script will retry the 'petalinux-build' step once on a failure:

    # Sometimes the build fails because of fetch or setscene issues, so we try another time

    petalinux-build -c ${PETALINUX_BUILD_IMAGE} || petalinux-build -c ${PETALINUX_BUILD_IMAGE}

  • in reply to narrucmot

    A second run of the ./make_minized.sh script went much better.

     

    It actually renamed the first project directory and created a new one but it finished with no issues in less than an hour.

     

    Now I have a stupid question.... What do I need to do to boot the created files?

     

    I would like to jtag boot the board first to make sure it works then I would like to put the new files on the MiniZed eMMC and boot it normally.

     

    Thanks for the help trying to figure this out. I still don't quite get how petalinux works (I'm more familiar with Buildroot) but at least I'm getting something to start with.
