Compile U-Boot Files For PYNQ-Z1 From Source

Hi folks,

since weeks I try to compile a u-boot version for the PYNQ-Z1 board. I want to work on some low-level programming for which I need a purely U-Boot systems (without a linux kernel or root file system). The u-boot system will load an image file and a bitstream file to run.

I followed the steps on:

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841973/Build+U-Boot

However it seems that I am missing the step to include the config files for the pynq-z1 board.
Furthermore 1. I don’t know where to get them nor 2. how to include them.

Please note, that I also tried some older version of the repository GitHub - Xilinx/u-boot-xlnx: The official Xilinx u-boot repository. However the older version have an old openSSL version, which my system cannot provide.

I appreciate every help.

Best

Ahmed
