ERROR: Failed to add user layer

Solution:

sudo sysctl -n -w fs.inotify.max_user_watches=524288

ERROR: Layer meta-altera-refdes is not compatible with the core layer which only supports these series: zeus (layer is compatible with thud)
Solution:
not found... or version BSP deffers from PetaLinux

Pynq Issue:

The PYNQ build flow isn’t compatible with Petalinux 2021.1 - please use the versions specified on this page PYNQ SD Card — Python productivity for Zynq (Pynq) 28 (2020.1 for PYNQ 2.6). We’re currently in the process of updating.

According to the log file :
ERROR: Layer meta-user is not compatible with the core layer which only supports these series: zeus (layer is compatible with gatesgarth)
you should set the correct layer support as follow: inside meta-user/conf/local.conf file, try to add:
LAYERSERIES_COMPAT_mensi-user= “zeus gatesgarth”

Adding this line to conf file worked for me LAYERSERIES_COMPAT_pynq = “zeus”

Install required packages for PetaLinux.
sudo apt-get install gawk python build-essential gcc git make zlib1g-dev gcc-multilib zlib1g:i386 gzip

Make the installer executable:
chmod +x petalinux-v2019.2-final-installer.run

Let /bin/sh be bash:

sudo dpkg-reconfigure dash

Then answer NO.

petalinux-build

Error:

ERROR: OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:

Failed to create a file in SSTATE_DIR: Permission denied.
You could try using /home/training/git/avnet/petalinux/scripts/../cache/2019_2/sstate_arm in SSTATE_MIRRORS rather than as an SSTATE_CACHE.

Solution:

I have commented last two lines in /project-spec/meta-user/conf/petalinuxbsp.conf
like this:
#DL_DIR = "/home/training/git/avnet/petalinux/scripts/../cache/2019_2/downloads"
#SSTATE_DIR = "/home/training/git/avnet/petalinux/scripts/../cache/2019_2/sstate_arm"

And for now it started building, lets hope, that it wont crash.

Problem description:

I forgot to 'undo' these file edits before posting this BSP online. Your fix to comment these lines in the petalinuxbsp.conf file is the correct one.
I am sorry for the inconvenience.

Error:

ERROR: petalinux-image-minimal-1.0-r0 do_image_wic: No kickstart files from WKS_FILES were found: petalinux-image-minimal.mz7010-fmccc.wks petalinux-image-minimal.wks. Please set WKS_FILE or WKS_FILES appropriately.

Solution:

I was able to avoid this error in Petalinux 2020.1 by using:

petalinux-build -c avnet-image-minimal
or
petalinux-build -c avnet-image-full

Another solution:

The 2020.1 Ultra96 BSP has the same error. I ran config and removed wic from the list of rootfs images that petalinux is trying to create.

How to free disk space after petalinux-build project is done:

$petalinux-build -x distclean
and
$petalinux-build -x mrproper

Try to remove folders:
/build
/project-spec/meta-user

P.S.
The contents present in meta-user are not auto generated, hence you should not remove it.
