Are you able to run the TCL script that generates the Vivado design without problems, or does it give you errors at that stage?
No, I'm not able to run the TCL script to completion. So far I have encountered two errors, the first was a version check so worked around this be setting 'version_override=yes'
The error I'm currently stuck on gives the error message:
ERROR: [Board 49-71] The board_part definition was not found for em.avnet.com:minized:part0:1.2. The project's board_part property was not set, but the project's part property was set to xc7z007sclg225-1. Valid board_part values can be retrieved with the 'get_board_parts' Tcl command. Check if board.repoPaths parameter is set and the board_part is installed from the tcl app store.
Overriding the tools version check is fine, as this build does work current tools versions (at the time that the script was generated, this could of course not be predicted). But to use MiniZed, you first have to exit Vivado, instal the board definition files in the Vivado tools directory, and then start Vivado again. Please see: "Board Definition Files" on minized.org/product/minized under "Documentation.
That got the TCL script to complete.
