Xilinx’s Wiki Instructions to Add Yocto Layer Fail with PetaLinux Tools 2017.4

This post lists an error I got while following the instructions for “Installing the meta-example layer on your host” listed on the “PetaLinux Yocto Tips” at http://www.wiki.xilinx.com/PetaLinux+Yocto+Tips.

TL;DR

The “Installing the meta-example layer on your host” instructions listed on the “PetaLinux Yocto Tips” at http://www.wiki.xilinx.com/PetaLinux+Yocto+Tips as of Mar 24 2018 @ 9:18 AM (MDT) did not work for me with PetaLinux 2017.4.

In addition, the wiki’s instructions conflict with an advisement given in a file the wiki says to edit.

Steps

1. Clone the repo:

git clone https://github.com/DynamicDevices/meta-example

2. Edit bblayers.conf:

vi ./build/conf/bblayers.conf

3. Add the path to meta-example:

/home/pfefferz/plprjs2/zcu102qemu/meta-example \

4. Source the PetaLinux Tools environment and build bbexample:

LOCALTOOLS=$HOME/tools
source $LOCALTOOLS/opt/pkg/petalinux/settings.sh
source $HOME/set_petalinux_env.sh
which make
which petalinux-create

pfefferz@plc2:~/plprjs2/zcu102qemu$ petalinux-build -c bbexample

5. Got the following error:

pfefferz@mach:~/plprjs2/zcu102qemu$ petalinux-build -c bbexample

[INFO] building bbexample

[INFO] sourcing bitbake

INFO: bitbake bbexample

6. Looked at build/conf/bblayers.conf and found that it had been regenerated as it warned at the top of the file:

# WARNING: this configuration has been automatically generated and in
# most cases should not be edited. If you need more flexibility than
# this configuration provides, it is strongly suggested that you set
# up a proper instance of the full build system and use that instead.
