+
+ZDS-II Compiler Versions
+========================
+
+Version 5.0.1
+
+  All testing has been performed with ZSD II verion 5.0.1 for the ZNEO.
+
+Other Versions
+
+  If you use any version of ZDS-II other than 5.0.1 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/16z/*/setenv.sh and (2) configs/16z/*/Make.defs. 
+  Simply edit these two files, changing 5.0.1 to whatever.
+
+Serial Console
+==============
+
+The 16z supports a single UART, UART0, that will be used to support the
+NuttX serial console.
+
+LEDs
+====
+
+The 16z board has 7 LEDs, five of which are controllable via software:
+
+  ----- ------ ------ ------------------------------------
+  LED   Color  Signal Description
+  ----- ------ ------ ------------------------------------
+  LED1  Red     3V3   Indicates the presence of +3.3V
+  LED2  Red     5V    Indicates the presence of +5V
+
+  LED3  Blue    ~RF   Controlled via PH2.  Notes: 1, 2
+  LED4  Green   ~SXM  Controlled via PH3.  Notes: 1, 3
+  LED5  Green   ~SD1  Controlled via PJ0.  Notes: 1, 4
+  LED6  Yellow  ~SD2  Controlled via PJ4.  Notes: 1, 5
+  LED7  Yellow  ~SD0  Controlled via PJ7.  Notes: 1, 6
+  ----- ------ ------ ------------------------------------
+
+  Note 1:  Pulled high so a low output illuminates the LED.
+  Note 2:  PH2/~RF is also used by the RF transceiver, X2.  That part is not
+           populated on my board.
+  Note 3:  ~SXM is the chip select for the serial memory, U4.  That part is
+           not populated on my board.
+  Note 4:  ~SD1 is the chip select for the SD card 1, X11.
+  Note 5:  ~SD2 is the chip select for the SD card 2, X10.
+  Note 6:  ~SD0 is the chip select for the microSD 0, X12.
+
+In conclusion:  None of the LEDs are available to indicate software status
+without potentially sacrificing board functionality.  If the RF transceiver
+is not installed (CONFIG_16Z_RFTRANSCEIVER=n) and if LED support is
+requested (CONFIG_ARCH_LEDS), then LED3 will be used to indicate status:  A
+solid color means that the board has boot successfully; flashing at a rate
+of approximately 2Hz indicates a software failure.
+
+RAM
+===
+
+The 16z has two IS66WVE4M16BLL 64Mb (4M x 16b) "Pseudo" SRAM parts on board.
+This provides a total of 16MiB of SRAM from program usage.
+
+Selecting Configurations
+========================
+
+Variations on the basic 16z configuration are maintained in subdirectories.
+To configure any specific configuration, do the following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh 16z/<sub-directory>
+   cd <nuttx-top-directory>
+   make
+
+Where <sub-directory> is the specific board configuration that you wish to
+build.  The following board-specific configurations are available.
+
+Before entering the make command, make certain that the path to the ZNEO
+compiler is in you PATH variable.  You make modify and use the setenv.sh
+script to set that PATH if you like.  You can simply source setenv.sh
+before making like:
+
+  ...
+  . ./setenv.sh
+  make
+
+
+Configuration Sub-directories
+=============================
+
+source/ and include/
+--------------------
+
+  These directories contain common logic for all 16z configurations.
+
+nsh
+---
+  nsh:
+    This configuration directory will built the NuttShell (NSH).  See
+    the NSH user manual in the documents directory (or online at nuttx.org).
+    See also the README.txt file in the nsh sub-directory for information
+    about using ZDS-II.
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+          and misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. By default, this configuration assumes that you are using the
+       Cygwin environment on Windows.  An option is to use the native
+       CMD.exe window build as described in the top-level README.txt
+       file.  To set up that configuration:
+
+       -CONFIG_WINDOWS_CYGWIN=y
+       +CONFIG_WINDOWS_NATIVE=y
+
+       And after configuring, make sure that CONFIG_APPS_DIR uses
+       the back slash character.  For example:
+
+        CONFIG_APPS_DIR="..\apps"
+
+      NOTES:
+
+      a. If you need to change the toolchain path used in Make.defs, you
+         will need to use the short 8.3 filenames to avoid spaces.  On my
+         PC, C:\PROGRA~1\ is is C:\Program Files\ and C:\PROGRA~2\ is
+         C:\Program Files (x86)\
+      b. I have not tried to use this configuration with the native
+         Windows build, but I would expect the same issues as is listed
+         for the ostest configuration..
+
+   STATUS:
+      Currently, NSH failes nsh_consoleoutput().  Here is an example.
+      This echo command causes the system to hang:
+
+        nsh> echo abc
+
+      Below is some annotated output from the debugger.  Here is the 30,000 ft view:
+
+        - cmd_echo loops for each argv[i], 1 >=i > argc.
+
+        - It calls:
+
+            vtbl->output(vtbl, "%s ", argv[i])
+
+          where the prototype for output is:
+
+            int (*output)(FAR struct nsh_vtbl_s *vtbl, const char *fmt, ...);
+
+        - vtbl->output maps to nsh_consoleoutput() in this case.
+
+        - cmd_echo passes all of the arguments to output in registers.
+
+        - nsh_consoleoutput expects all of the parameters on the stack.
+
+        - nsh_console calls vfprintf() using bad values from the stack.
+
+        - vfprintf crashes and never returns.
+
+      Looks like a compiler bug to me.

+ostest
+------
+
+    This builds the examples/ostest application for execution from FLASH.
+    See the README.txt file in the ostest sub-directory for information
+    about using ZDS-II.  See also apps/examples/README.txt for information
+    about ostest.
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+          and misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. By default, this configuration assumes that you are using the
+       Cygwin environment on Windows.  An option is to use the native
+       CMD.exe window build as described in the top-level README.txt
+       file.  To set up that configuration:
+
+       -CONFIG_WINDOWS_CYGWIN=y
+       +CONFIG_WINDOWS_NATIVE=y
+
+       And after configuring, make sure that CONFIG_APPS_DIR uses
+       the back slash character.  For example:
+
+        CONFIG_APPS_DIR="..\apps"
+
+      NOTES:
+
+      a. If you need to change the toolchain path used in Make.defs, you
+         will need to use the short 8.3 filenames to avoid spaces.  On my
+         PC, C:\PROGRA~1\ is is C:\Program Files\ and C:\PROGRA~2\ is
+         C:\Program Files (x86)\
+      b. You can't use setenv.sh in the native Windows environment.  Try
+         scripts/setenv.bat instead.
+      c. At present, the native Windows build fails at the final link stages.
+         The failure is due to problems in arch/z16/src/nuttx.linkcmd that
+         is autogenerated by arch/z16/src/Makefile.  The basic problem
+         is the spurious spaces and and carrirage returns are generated at
+         the end of the lines after a line continuation (\ ^M).  If these
+         trailing bad characters are manually eliminated, then the build
+         will succeed on the next try.
+
+pashello
+--------
+
+    Configures to use examples/pashello for execution from FLASH
+    See examples/README.txt for information about pashello.
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
+          and misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. The last time I tried building this configuration, there were
+       a few undefined symbols from the PCODE logic.  It might require
+       a little TLC to get this all working again.
+
+    3. The native windows build has not been tried with this configuration
+       but should, in principle, work (see notes for the ostest configuration
+       above).
+
+Check out any README.txt files in these <sub-directory>s.

+/* LEDs
+ *
+ * The 16z board has 7 LEDs, five of which are controllable via software:
+ *
+ *   ----- ------ ------ ------------------------------------
+ *   LED   Color  Signal Description
+ *   ----- ------ ------ ------------------------------------
+ *   LED1  Red     3V3   Indicates the presence of +3.3V
+ *   LED2  Red     5V    Indicates the presence of +5V
+
+ *   LED3  Blue    ~RF   Controlled via PH2.  Notes: 1, 2
+ *   LED4  Green   ~SXM  Controlled via PH3.  Notes: 1, 3
+ *   LED5  Green   ~SD1  Controlled via PJ0.  Notes: 1, 4
+ *   LED6  Yellow  ~SD2  Controlled via PJ4.  Notes: 1, 5
+ *   LED7  Yellow  ~SD0  Controlled via PJ7.  Notes: 1, 6
+ *   ----- ------ ------ ------------------------------------
+ *
+ *   Note 1:  Pulled high so a low output illuminates the LED.
+ *   Note 2:  PH2/~RF is also used by the RF transceiver, X2.  That part is not
+ *            populated on my board.
+ *   Note 3:  ~SXM is the chip select for the serial memory, U4.  That part is
+ *            not populated on my board.
+ *   Note 4:  ~SD1 is the chip select for the SD card 1, X11.
+ *   Note 5:  ~SD2 is the chip select for the SD card 2, X10.
+ *   Note 6:  ~SD0 is the chip select for the microSD 0, X12.
+ *
+ * In conclusion:  None of the LEDs are available to indicate software status
+ * without potentially sacrificing board functionality.  If the RF transceiver
+ * is not installed (CONFIG_16Z_RFTRANSCEIVER=n) and if LED support is
+ * requested (CONFIG_ARCH_LEDS), then LED3 will be used to indicate status:  A
+ * solid color means that the board has boot successfully; flashing at a rate
+ * of approximately 2Hz indicates a software failure.

+
+NSH Project
+-----------
+
+nsh.zfpproj is a simple ZDS II - ZNEO 5.0.1 project that will allow you
+  to use the ZDS-II debugger.  Before using, copy the following files from
+  the toplevel directory:
+
+    nuttx.hex, nuttx.map, nuttx.lod
+
+  to this directory as:
+
+    nsh.hex, nsh.map, nsh.lod
+
+Loading and Executing Code
+--------------------------
+
+1. Copy the files to this directory as described above
+2. Connect the ZiLOG XTools USB debugger.
+3. Install the USB driver from the ZDS-II device_drivers directory
+4. Start ZDS-II and load the nsh.zfpproj project
+5. In the debug tab, connect to the debugger
+6. In the debug tab, load code, reset, and go
+
+Console Output
+--------------
+
+Interaction with NSH is via the serial console at 57600 8N1 baud.
+
+STATUS
+------
+1. This configuration does not run correctly.  There is a problem with the
+   serial driver.  When started, some garbled characters appear on the
+   console.  I suspect (a) the UART is not being configured correctly, and
+   (2) UART interrupts are not be set up correctly.
+
+2. I bet that this code, like ostest, will not run if started by a hardware
+   reset.  It may only run when started via the debugger.

+
+OSTEST Project
+--------------
+
+ostest.zfpproj is a simple ZDS II - ZNEO 5.0.1 project that will allow you
+  to use the ZDS-II debugger.  Before using, copy the following files from
+  the toplevel directory:
+
+    nuttx.hex, nuttx.map, nuttx.lod
+
+  to this directory as:
+
+    ostest.hex, ostest.map, ostest.lod
+
+ostest.zdzbak is a project file for an older ZDS-II 4.0 version (There is no
+  difference in the files other than for some versioning information at the
+  top).
+
+Loading and Executing Code
+--------------------------
+
+1. Copy the files to this directory as described above
+2. Connect the ZiLOG XTools USB debugger.
+3. Install the USB driver from the ZDS-II device_drivers directory
+4. Start ZDS-II and load the ostest.zfpproj project
+5. In the debug tab, connect to the debugger
+6. In the debug tab, load code, reset, and go
+
+Hmmm... it appears that the code does not run if started by a hardware reset.
+It runs only when started via the debugger.  What is up with that?
+
+Console Output
+--------------
+
+OS test results will be provided on the serial console at 57600 8N1 baud.

+correct and I suspect some system timing issues.

+/* LEDs
+ *
+ * The 16z board has 7 LEDs, five of which are controllable via software:
+ *
+ *   ----- ------ ------ ------------------------------------
+ *   LED   Color  Signal Description
+ *   ----- ------ ------ ------------------------------------
+ *   LED1  Red     3V3   Indicates the presence of +3.3V
+ *   LED2  Red     5V    Indicates the presence of +5V
+
+ *   LED3  Blue    ~RF   Controlled via PH2.  Notes: 1, 2
+ *   LED4  Green   ~SXM  Controlled via PH3.  Notes: 1, 3
+ *   LED5  Green   ~SD1  Controlled via PJ0.  Notes: 1, 4
+ *   LED6  Yellow  ~SD2  Controlled via PJ4.  Notes: 1, 5
+ *   LED7  Yellow  ~SD0  Controlled via PJ7.  Notes: 1, 6
+ *   ----- ------ ------ ------------------------------------
+ *
+ *   Note 1:  Pulled high so a low output illuminates the LED.
+ *   Note 2:  PH2/~RF is also used by the RF transceiver, X2.  That part is not
+ *            populated on my board.
+ *   Note 3:  ~SXM is the chip select for the serial memory, U4.  That part is
+ *            not populated on my board.
+ *   Note 4:  ~SD1 is the chip select for the SD card 1, X11.
+ *   Note 5:  ~SD2 is the chip select for the SD card 2, X10.
+ *   Note 6:  ~SD0 is the chip select for the microSD 0, X12.
+ *
+ * In conclusion:  None of the LEDs are available to indicate software status
+ * without potentially sacrificing board functionality.  If the RF transceiver
+ * is not installed (CONFIG_16Z_RFTRANSCEIVER=n) and if LED support is
+ * requested (CONFIG_ARCH_LEDS), then LED3 will be used to indicate status:  A
+ * solid color means that the board has boot successfully; flashing at a rate
+ * of approximately 2Hz indicates a software failure.
