why is the /piton/design/f1 is empty

[AnouarNechi]

I trying to build an FPGA image for AWS F1 and I fillowed the exact steps as in readme.md.
I got an error message saying that I cannot download submodule F1 and the F1 folder is empty. Is this normal.
Should I download it manually?

Try switching to openpiton-dev. I think we had the F1 submodule set to use SSH instead of HTTPS. That should be fixed in openpiton-dev. Then if you run the git submodule update --init --recursive it should check out the f1 submodule.
