Thx for the reply. This is what I did:
In flake.nix from ARTIQ:
vivado = pkgs.buildFHSEnv {
name = "vivado";
targetPkgs = vivadoDeps;
profile = "set -e; source /mnt/c/Xilinx/Vivado/2022.2/settings64.sh";
runScript = "vivado";
};
In flake.nix from ARTIQ-zynq:
'inputs.artiq.url = "path:/mnt/c/Users/lf/Documents/codes/hardware/artiq/artiq"
'

Following the instructions in the manual I typed nix flake update and nix develop after every flake.nix change and got messages showing my changes.

I also changed the build command:
nix build --print-build-logs --impure --expr 'let fl = builtins.getFlake "/mnt/c/Users/lf/Documents/codes/hardware/artiq/artiq-zynq"; in (fl.makeArtiqZynqPackage {target="kasli_soc"; variant="standalone"; json=./default.json;}).kasli_soc-standalone-sd'

I will continue looking for the origin of the error.

    Thanks for the reply. I tried to substitute the extra-sandbox-paths="/opt" to the location of my vivado with what you suggest, as well as with /mnt/c, but I still get the same error.

    Hi again,
    I decided to do it on Linux and installed everything as is suggested in the instructions. Given that all is the same, once I downloaded the artiq-zynq pachage (its release-8), I just executed nix develop and then nix build --print-build-logs --impure --expr 'let fl = builtins.getFlake "git+https://git.m-labs.hk/m-labs/artiq-zynq?ref=release-8"; in (fl.makeArtiqZynqPackage {target="kasli_soc"; variant="standalone"; json=./basic.json;}).kasli_soc-standalone-sd'

    The error I get is the same:

    I checked that the file settings64.sh exists. I also looked int /etc/profile and it only has 27 lines of code.

    My artiq-zynq package is NOT in /opt, but this should not be the problem.

    Any idea?

    I forgot to say that I am using Ubuntu 22.04.4 LTS

    Step 5 solved the problem. Thank you very much!

    @esavkin You could also set up an apparmor profile for Nix and possibly merge it upstream. But, of course, that takes more work.

    Hi I have a similar problem to lf_10 in which I have attempted to follow the same method in order to alleviate my problem.
    The following was entered:

    rabi@artiq ~> sudo nix build --print-build-logs --impure --expr 'let fl = builtins.getFlake "/home/rabi/artiq-zynq"; in (fl.makeArtiqZynqPackage {target="kasli_soc"; variant="standalone"; json=/home/rabi/auckland.json;}).kasli_soc-standalone-sd'

    This resulted in the following error:

OSError: Subprocess failed

    Prior to reading through this thread I originally was struggling to get past having the vivado directory being from /opt/
    after following the instructions from architeuthis and fsagbuya such as cloning both artiq and artiq-zynq and proceeding to change the source and inputs.artiq.url, as well as including my vivado location to my sandbox-paths.

    I have now progressed to having

    USER LED at RTIO channel 0x000015
/etc/profile: line 36: /home/rabi/Xilinx/Vivado/2022.2/settings64.sh: No such file or directory

    instead of:

    USER LED at RTIO channel 0x000015
/etc/profile: line 36: /opt/Xilinx/Vivado/2022.2/settings64.sh: No such file or directory

    the directory /home/rabi/Xilinx/Vivado/2022.2/settings64.sh, does indeed exist, as well as having the following permissions

    rabi@artiq ~> ls  -l /home/rabi/Xilinx/Vivado/2022.2/settings64.sh
-rwxr-xr-x 1 rabi users 508 Jan  8 22:50 /home/rabi/Xilinx/Vivado/2022.2/settings64.sh

    I am very new to linux, nixos, and artiq, so there is a high chance I have missed something simple. However I am able to run vivado outside of the context of this nix build command.

    If anyone could help out, I'd greatly appreciate it 🙂

    Happy New Year!

        Hi @hoogeroo , you will need to add the specified directory to the sandbox in flake in extra-sandbox-paths = "/opt"; and in trusted settings file.

          esavkin

          Thanks for the quick response yesterday

          I believe I have changed my path in the flake, and the sandbox. I installed my vivado in /home/rabi/Xilinx/

          artiq flake:

          vivado = pkgs.buildFHSEnv {
  name = "vivado";
  targetPkgs = vivadoDeps;
  profile = "set -e; source /home/rabi/Xilinx/Vivado/2022.2/settings64.sh";
  runScript = "vivado";
};

          extra-sandbox-paths = "/home/rabi/Xilinx";
          };

          trusted settings; in .local/share/nix:

          "extra-sandbox-paths":{"/home/rabi/Xilinx":true},

          Just for some extra errors,

          when I try to source /home/rabi/Xilinx/Vivado/2022.2/settings64.sh inside fish I get:
