I have previously managed to build artiq-zynq but having returned to it recently, I'm seeing the following errors. This is on a clean checkout of the release-7 branch and a brand new Nix installation. I thought I might have corrupted something in my nix env so tried a fresh installation.

This seems to be due to a difference in the flake.lock file for misoc. If I update the narHash field for misoc to the expected value, then it all Just Works.

My Nix knowledge is non-existent so I have no idea how that lock file is constructed. Deleting it and rebuilding didn't help.

I tried also a clean checkout of release-7 branch, but have not encountered the issue. Can you share the the contents of your flake.lock file before you update it?

Sorry, I missed your post.

The contents of flake.lock are unmodified from the HEAD of the branch. I'm using nix 2.21.1

A nix store gc didn't help. Are there any other useful nix commands to clean and start from a fresh build?

I managed to reproduce this using the latest nix 2.22.0. It seems this is related on the changes in supporting submodules as a nix flake input. Will check on how it is implemented now and submit a PR. In the meantime, the simplest workaround is to revert to nix 2.18.

Hi @shareef. I tested again and followed the troubleshooting steps indicated here:

I was able to avoid those NAR mismatch errors and run ARTIQ without changing anything in the source code.

You might need to reboot your machine for the configuration to take effect.
