unable to build a given buildroot config

[wucke13]

I'm trying to build the config found in https://github.com/analogdevicesinc/buildroot/tree/e783aadccebad3413b3d60fcfe98a25eb395d839 (as that builds the userspace of https://github.com/analogdevicesinc/plutosdr-fw). Unfortunately, the build of the lockfile fails right-away:

This can happen if there is a source tarball in buildroot that does not have a corresponding hash checked in to a .hash file. This is valid in buildroot, but nix requires a hash for all downloaded sources, so my make-package-lock.py will raise an error in this case.

To work around this, you can either add a corresponding .hash file to the buildroot repo or add extraSha256Hashes to the mkBuildroot invocation in your flake. Something like extraSha256Hashes = { "libini-a467418-br1.tar.gz" = <sha256 of the downloaded file>;}

So I put

let
  buildrootPackages = buildroot-nix.lib.mkBuildroot {
    inherit pkgs;
    name = "pluto-rootfs";
    defconfig = "zynq_pluto_defconfig";
    lockfile = ./buildroot.lock;
    src =
      (pkgs.fetchFromGitHub {
        inherit (self.packages.${system}.pluto-image.src) owner repo rev;
        fetchSubmodules = true;
        hash = "sha256-MKlTUqtly7oINQg2rhoWejiILn8PWMoLNJUVg6G/prg=";
      })
      + "/buildroot";
    extraSha256Hashes = {
      "libini-a467418-br1.tar.gz" = "sha256-MKlTUqtly7oINQg2rhoWejiILn8PWMoLNJUVg3G/prg=";
      "libini-a467418" = "sha256-MKlTUqtly7oINQg2rhoWejiILn8PWMoLNJUVg3G/prg=";
    };
  };
in
buildrootPackages.packageLockFile;

but still I get the same error? Also, the URL is bogus, as in it returns 404. Also libini-a467418-br1.tar.gz does not match in the repo, so where is this URL coming from?

Also, the package is probably hosted externally:
