−Two programs are currently buildable in this target-utils tree: loadagent and
+
−pirexplore.  Loadagent is built to be loaded and run out of the Calypso internal
+
−(on-chip) RAM, and does not depend on any hardware outside of the Calypso chip
+
−itself - thus it should run unchanged on all Calypso targets.  It expects to be
+
−loaded by the Calypso ROM bootloader in the UART download mode, and it reads a
+
−RAM variable left behind by the ROM code that indicates which UART has been used
+
−to perform that download - it then uses that same UART to communicate with the
+
−host, presenting an interactive command prompt.  You can run loadagent "raw" by
+
−loading loadagent.srec with fc-iram, but normally it is used "behind the scenes"
+
−by fc-loadtool and fc-xram.
+

+
−Pirexplore is built in the same manner as loadagent (also runs out of IRAM,
+
−expects to be loaded with fc-iram, and presents an interactive command prompt
+
−on the autodetected UART), but it automatically performs some hardware (board
+
−level) initialization specific to the Pirelli, and offers additional commands
+
−for exploring the hardware features of this device.
