I am making this post to let you know that we here at Avnet have generated and posted quite a few PetaLinux BSPs and SDSoC platforms (with examples) for our products!
These are all for PetaLinux and SDSoC 2019.1 unless noted. Items that are not filled in or do NOT have links yet, are in the works or not being actively supported as of this post. Those products can be accessed through the Product link column and all of the original materials are listed there!
I'll update this list as we post more. All of the links used are SURLS, which will allow you to keep a perma-link of sorts to always get the latest platforms/BSPs! If you need an older file, again, you can access those through the product pages!
