+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development
+  environment. The source has been built only using the GNU toolchain
+  (see below).  Other toolchains will likely cause problems.
+
+NuttX Buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the HC12 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no HC12 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin
+  environments.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh demo9s12nec64/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/m9s12x-defconfig-3.3.6 .config
+
+  6. make oldconfig
+
+  7. make
+
+     If the make fails because it can't find the file to download, you may
+     have to locate the file on the internet and download it into the archives/
+     directory manually.  For example, binutils-2.18 can be found here:
+     http://ftp.gnu.org/gnu/binutils/
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+FreeScale HCS12 Serial Monitor
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  General:
+    The NuttX HCS12 port is configured to use the Freescale HCS serial
+    monitor.  This monitor supports primitive debug commands that allow
+    FLASH/EEPROM programming and debugging through an RS-232 serial
+    interface.  The serial monior is 2Kb in size and resides in FLASH at
+    addresses 0xf800-0xffff.  The monitor does not use any RAM other than
+    the stack itself.
+
+  AN2458
+    The serial monitor is described in detail in Freescale Application
+    Note AN2458.pdf.
+
+  COP:
+    The serial monitor uses the COP for the cold reset function and should
+    not be used by the application without some precautions (see AN2458).
+
+  Clocking:
+    The serial monitor sets the operating frequency to 24 MHz.  This is
+    not altered by the NuttX start-up; doing so would interfere with the
+    operation of the serial monitor.
+
+  Memory Configuration:
+    Registers:
+    • Register space is located at 0x0000–0x03ff.
+    FLASH:
+    • FLASH memory is any address greater than 0x4000. All paged
+      addresses are assumed to be FLASH memory.
+    • Application code should exclude the 0xf780–0xff7f memory.
+    SRAM:
+    • RAM ends at 0x3FFF and builds down to the limit of the device’s
+      available RAM.
+    • The serial monitor's stack pointer is set to the end of RAM+1
+      (0x4000).
+    EEPROM:
+    • EEPROM (if the target device has any) is limited to the available
+      space between the registers and the RAM (0x0400–to start of RAM).
+    External Devices:
+    • External devices attached to the multiplexed external bus
+      interface are not supported
+
+  Serial Communications:
+    The serial monitor uses RS-232 serial communications through SCI0 at
+    115,200 baud. The monitor must have exclusive use of this interface.
+    Access to the serial port is available through a monitor jump table.
+
+  Interrrupts:
+    The serial monitor redirects interrupt vectors to an unprotected
+    portion of FLASH just before the protected monitor program
+    (0xf780–0xf7fe).  The monitor will automatically redirect vector
+    programming operations to these user vectors.  The user code should
+    therefore keep the normal (non-monitor) vector locations
+    (0xff80–0xfffe).
+
+Soft Registers
+^^^^^^^^^^^^^^
+
+  The mc68hcs12 compilation is prone to errors like the following:
+
+    CC:  lib_b16sin.c
+    lib_b16sin.c: In function `b16sin':
+    lib_b16sin.c:110: error: unable to find a register to spill in class `S_REGS'
+    lib_b16sin.c:110: error: this is the insn:
+    (insn:HI 41 46 44 8 (parallel [
+                (set (subreg:SI (reg:DI 58 [ rad ]) 4)
+                    (reg/v:SI 54 [ rad ]))
+                (clobber (scratch:HI))
+            ]) 20 {movsi_internal} (insn_list 46 (nil))
+        (expr_list:REG_UNUSED (scratch:HI)
+            (expr_list:REG_NO_CONFLICT (reg/v:SI 54 [ rad ])
+                (nil))))
+    lib_b16sin.c:110: confused by earlier errors, bailing out
+
+  There are several ways that this error could be fixed:
+
+  1. Increase the number of soft registers (i.e., "fake" registers defined
+     at fixed memory locations).  This can be done by adding something like
+     -msoft-reg-count=4 to the CFLAGS.  This approach was not taken
+     because:
+
+     - This slows hcs12 performance
+     - All of these soft registers wouil have to be saved and restored
+       on every interrupt and context switch.
+
+  2. Lowering the optimization level by dropping -Os to -O2 or, more likely,
+     by removing -fomit-frame-pointer.  Also not desireable becauase 99% of the
+     files that do not have this problem also increase in size.  Special case
+     compilation with reduced optimization levels just for the files that need
+     it could be done, but this would complicate the make system.
+
+  3. Restructuring files to reduce the complexity.  If you add local variables
+     to hold intermediate computational results, this error can be eliminated.
+     This is the approach taken in NuttX.  It has disadvantages only in that
+     (1) it takes some effort and good guessing to eliminate the problem, and (2)
+     the problem is not really eliminated -- it can and will re-occur when files
+     are changed or new files are added.
+
+  4. Many files are built that are needed by DEM09S12NE64.  Another very simple
+     option if those problem files are needed is to just remove the offending
+     files from the Make.defs file so that they no longer cause a problem.
+
+HCS12/DEMO9S12NEC64-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=hc
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_HC=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_HCS12=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=mc92s12nec64
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_MCS92S12NEC64
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=demo9s12nec64
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_DEMOS92S12NEC64 (for the Freescale DEMO9S12NE64 development board)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed RAM.
+
+	CONFIG_DRAM_START - The start address of installed RAM
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  GPIO Interrupts
+  
+    CONFIG_GPIO_IRQ - Enable general support for GPIO IRQs
+    CONFIG_HCS12_PORTG_INTS - Enable PortG IRQs

+    CONFIG_HCS12_PORTJ_INTS - Enable PortJ IRQs
+   
+  HCS12 build options:
+
+	CONFIG_HCS12_SERIALMON - Indicates that the target systems uses
+	  the Freescale serial bootloader.
+
+	CONFIG_HCS12_NONBANKED - Indicates that the target systems does not
+	  support banking.  Only short calls are made; one fixed page is
+	  presented the the paging window.  Only 48Kb of FLASH is usable
+	  in this configuration: pages 3e, 3d, then 3f will appear as a
+	  contiguous address space in memory.
+
+  HCS12 Sub-system support
+
+	CONFIG_HCS12_SCI0
+	CONFIG_HCS12_SCI1
+
+  HCS12 specific device driver settings:
+
+	CONFIG_SCIn_SERIAL_CONSOLE - selects SCIn for the console and ttys0
+	  (default is the SCI0).
+
+	CONFIG_SCIn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+
+	CONFIG_SCIn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+
+	CONFIG_SCIn_BAUD - The configure BAUD of the UART.
+
+	CONFIG_SCIn_BITS - The number of bits.  Must be either 7 or 8.
+
+	CONFIG_SCIn_PARTIY - 0=no parity, 1=odd parity, 2=even parity, 3=mark 1, 4=space 0
+
+	CONFIG_SCIn_2STOP - Two stop bits
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Freescale HCS12 configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh demo9s12nec64/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+ostest:
+  This configuration directory, performs a simple OS test using
+  examples/ostest.

+ *   provided by board-specific logic.  They are implementations of the select
+ *   and status methods of the SPI interface defined by struct spi_ops_s (see

+ *   are provided by common HCS12 logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in hcs12_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide hcs12_spiselect() and hcs12_spistatus() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).
