The Zedboard (and many other boards) can no longer be installed in Vivado 2025.2. Looking at the file [https://github.com/Xilinx/XilinxBoardStore/blob/2025.2/catalog/vivado_2025.2.json](https://github.com/Xilinx/XilinxBoardStore/blob/2025.2/catalog/vivado_2025.2.json), it seems the boards are missing.
