That=E2=80=99s because =E2=80=9Copenfwwf-firmware=E2=80=9D is not the right=
 package name, or is
not found.  Perhaps you need to adjust GUIX_PACKAGE_PATH so that the
recipe for =E2=80=9Copenfwwf-firmware=E2=80=9D is found?

> bash: /sys/module/firmware_class/parameters/path: Permiso denegado

That=E2=80=99s because this is not performed as root.  This needs to be don=
e in
a =E2=80=9Croot=E2=80=9D shell, so:

  sudo bash
  export GUIX_PACKAGE_PATH=3D/path/to/recipes
  echo -n $(guix build openfwwf-firmware)/lib/firmware > \
     /sys/module/firmware_class/parameters/path

Could you try again?

(Please paste the exact commands and output in your reply.)

Thanks,
Ludo=E2=80=99.
