Integrate SWUpdate into a PetaLinux Project

yocto_project

This post lists steps to integrate SWUpdate into a PetaLinux Project.

The results have not been thoroughly tested.

Steps

1. Clone the SWUpdate meta layer into ext_source:

cd components
mkdir -p ext_source
cd ext_source
git clone https://github.com/sbabic/meta-swupdate.git 
cd meta-swupdate
git checkout morty

2. Download these patches to the meta-swupdate directory

3. Apply the patches:

patch -p1 < patch1.txt
patch -p1 < patch2.txt

4. Follow the instructions for adding a layer listed in link (but use meta-swupdate instead of the example) and add the following to project-spec/meta-user/conf/petalinucbsp.conf:

You should have approximately these diffs once you’re done:

Reference

swupdate documentation is at https://sbabic.github.io/swupdate/
The Xilinx + Yocto graphic is an amalgamation of Xilinx and Yocto icons.

Notes

You’ll get SWUpdate 2017.1 with this method. Take a look at this link to see how to figure this out.
