I would like to build artiq (the tip version) from source and I followed the directions in the manual, but I encountered the same problem as described in this post, https://forum.m-labs.hk/d/298-up-to-date-development-instructions

In a reply, SB recommended to install nixUnstable which I did and airwoodix recommended modifying the config file, I did that too and restarted nix. I cd into artiq and execute nix develop and my environment is configured. After that I "nix build" which does populate the result/ directory but it doesn't take any time, so that makes me think that something went wrong. Is this the correct procedure? Am I in a position to flash the Sinara at this point?

Again, thanks for your support. --Melanie

    This is no longer necessary since the nix 2.4 release.

    It probably used the cache.

    For your system the correct firmware rebuild procedure is nix develop github:m-labs/artiq and then python -m artiq.gateware.targets.kasli_generic aq.json
