   nutt.hex in the top-level directory. That is the file that you should
   provide to the DFU File Manager. You will end up with a file called
   nuttx.dfu that you can use with the STMicro DFU SE program.
+
+Configurations
+==============
+
+  Information Common to All Configurations
+  ----------------------------------------
+  Each Maple configuration is maintained in a sub-directory and
+  can be selected as follow:
+
+    cd tools
+    ./configure.sh maple/<subdir>
+    cd -
+    . ./setenv.sh
+
+  Before sourcing the setenv.sh file above, you should examine it and perform
+  edits as necessary so that TOOLCHAIN_BIN is the correct path to the directory
+  than holds your toolchain binaries.
+
+  And then build NuttX by simply typing the following.  At the conclusion of
+  the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
+
+    make
+
+  The <subdir> that is provided above as an argument to the tools/configure.sh
+  must be is one of the following.
+
+  NOTES:
+
+  1. These configurations use the mconf-based configuration tool.  To
+    change any of these configurations 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.
+
+  Configuration Sub-directories
+  -----------------------------
+
+  nsh:
+
+    This configuration directory provide the basic NuttShell (NSH).
+    A serial console is provided on USART1.
+
+    NOTES:
+    1. Currently configured for the STM32F103CB.  But this is easily
+       reconfigured:
+
+       CONFIG_ARCH_CHIP_STM32F103RB=n
+       CONFIG_ARCH_CHIP_STM32F103CB=y
+
+    2. Support for the I2C tool has been disabled, but can be restored
+       with following configure options:
+
+       System Type -> Peripherals
+         CONFIG_STM32_I2C1=y

+
+  nx:
+
+    This configuration has been used to bring up the  Sharp Memory LCD
+    on a custom board.  This NX configuration was used for testing that
+    LCD.  Debug output will appear on USART1.
+
+    NOTES:
+    1. Currently configured for the STM32F103CB.  But this is easily
+       reconfigured:
+
+       CONFIG_ARCH_CHIP_STM32F103RB=n
+       CONFIG_ARCH_CHIP_STM32F103CB=y
+
+    2. You won't be able to buy a Sharp Memory LCD to use with your
+       Maple.  If you want one, you will have to make one yourself.
+
+  usbnsh:
+
+    This is an alternative NuttShell (NSH) configuration that uses a USB
+    serial console for interaction.

+ *   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 STM32 logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() 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).
