Arty S7-50 support
I've got an Arty S7-50 and I don't see it in boards. I've got an sdcard pmod on JA, ESP32 on JC, and the OLED RGB screen on JD. I'm not sure how to add support but if there's a guide or a similar board that is already supported then I might be able to get it work. If I can create support using Vivado's IP builder then that would be much easier.
Yes, you can use Vivado's IP builder to modify a project created for a similar board that is already supported. For example, you can use Nexys A7 project as starting point.
To create and open Nexys A7 project: checkout the repository, install required packages and update submodules (see README). Then run:
source /opt/Xilinx/Vivado/2022.1/settings64.sh
make CONFIG=rocket64b1 BOARD=nexys-a7-100t vivado-gui
Save the project as, for example, workspace/rocket64b1/vivado-arty-s7-50-riscv, change the board name, open and edit IP block design, etc.
Alright, I'm starting to get things working. Hopefully I can work on this on nixOS and Vivado running in a Flatpak. Only problem I've found so far is no nix shell file.
Unfortunately, I cannot get it to work as it says dtc cannot be found and the Flatpak for Vivado doesn't have Java. It seems the way nixOS is set up makes Vivado not work outside of the Flatpak.
I'm not familiar with Flatpak, but I think it will not work. Rocket Chip RISC-V is a huge project, it needs powerful PC and tons of software to build, dtc and Java are just tip of the iceberg. To save time, I recommend to follow instructions, starting with fresh installation of Ubuntu.
I have no hardware that I can install Ubuntu on and I have no free drives for dual booting.
