That’s because “openfwwf-firmware” is not the right package name, or is
not found.  Perhaps you need to adjust GUIX_PACKAGE_PATH so that the
recipe for “openfwwf-firmware” is found?

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

That’s because this is not performed as root.  This needs to be done in
a “root” shell, so:

  sudo bash
  export GUIX_PACKAGE_PATH=/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’.
