−The /opt/freecalypso host directory tree used by the present FC host tools
+
−package and by various add-ons to it does NOT follow the traditional Unix/Linux
+
−file system hierarchy standard (FHS), instead it is a highly specialized
+
−directory tree that is meant to be private to FreeCalypso, with its structure
+
−defined solely by the Mother and no one else.  The following subdirectories are
+
−currently defined:
+
−
+
−aud-*: these directories appear if you install our optional
+
−fc-audio-config package, and contain subtrees to be uploaded by
+
−production line scripts into target device FFS under /aud via fc-fsio.
+
−
+
−batteries and charging: these subtrees come from fc-battery-conf
+
−(optional just like fc-audio-config) and are meant to be used with
+
−fc-fsio write-battery-table and write-charging-config commands.
+
−
+
−bin and include are the only subdirectories under /opt/freecalypso
+
−which follow traditional UNIX directory layout; include was added so
+
−that packages external to the core FC host tools package like
+
−fc-rfcal-tools and freecalypso-ui-dev can use rvinterf headers.
+
−
+
−gcc: the recommend install location for our ARM7 gcc toolchain is
+
−/opt/freecalypso/gcc.
+
−
+
−helpfiles subdir contains help files for those FC host utilities which
+
−implement a help command.
+
−
+
−loadtools subdir contains hardware parameter files and init scripts
+
−which underlie the all-important -h option to fc-loadtool, fc-iram and
+
−fc-xram, collectively known as loadtools.
+
−
+
−rfcal subdir only appears if you are doing RF calibration and install
+
−fc-rfcal-tools, and some of the necessary config files under that
+
−subdir you have to create yourself using your own RF knowledge specific
+
−to your particular setup.
+
−
+
−target-bin contains ARM7 target binaries used under the hood by
+
−loadtools.
+
−
+
−The basic minimal form of the /opt/freecalypso tree is populated when
+
−you install FC host tools, but it is further enriched if and when you
+
−install further add-ons (fc-audio-config, fc-battery-conf,
+
−fc-rfcal-tools) which are more specialized and not required for all
+
−users.  I expect to have more additions in the future: for example,
+
−when we start using the Melody E1 mechanism in our planned FC Libre
+
−Dumbphone, there will be a FreeCalypso ringtones package that will
+
−install E1-format melody files somewhere under /opt/freecalyso, to be
+
−subsequently uploaded into the actual phones via fc-fsio, initially at
+
−production time and optionally by end users.
