[setups/vivado] Mention the XHub Stores menu item for installing board support

[henrikbrixandersen]

If board support files are not installed prior to creating the project it will fail in a non-obvious way.

Good point! That should be in the documentation for future setups. 👍

Right now, the Vivado setups do not depend on any pre-installed board support files (everything that is required comes with the setup files).

However, I just stumbled across zephyrproject-rtos/zephyr#39162 (review). Seems like the Vivado TCL files are outdated (wrong reference to sim folder; undeclared fileset_neorv32 variable). I will fix that ASAP 😉

Even for the Arty?

Way ahead of you: #175 ;-)

I do think so.
I just made a clean re-install of Vivado without any board support files and the Arty setup synthesizes like a charm.

Did you remove the user-local board support files?

The Arty project scripts starts by setting up the board (

neorv32/setups/vivado/arty-a7-test-setup/create_project.tcl

Line 1 in c34416b

set board "arty-a7-35"

) and my clean install of Vivado 2020.02 required me to install the board support first.

Perhaps later versions of Vivado ship with Arty board support?

I think you are right... I did not realize that...

However, I am wondering if the board files are actually used by the synthesis 🤔 pin-mapping and actual part ID are defined by the provided setups scripts...

Anyway, including the official board support files is the way to go. 👍
These files also help with configuring the MIG for external memory. That could be very useful for more sophisticated setups in the future.
