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:

2. Edit bblayers.conf:

3. Add the path to meta-example:

4. Source the PetaLinux Tools environment and build bbexample:

5. Got the following error:

Summary: There was 1 ERROR message shown, returning a non-zero exit code. ERROR: Failed to build bbexample webtalk failed:PetaLinux statistics:extra lines detected:notsent_nofile! webtalk failed:Failed to get PetaLinux usage statistics!

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