+configs/pic32mz-starterkit README
+===============================
+
+This README file discusses the port of NuttX to the Microchip PIC32MZ
+Embedded Connectivity (EC) Starter Kit.  There are two configurations of the
+starter kit:
+
+  1) The PIC32MZ Embedded Connectivity Starter Kit based on the
+     PIC32MZ2048ECH144-I/PH chip (DM320006), and
+  2) The PIC32MZ Embedded Connectivity Starter Kit based on the
+     PIC32MZ2048ECM144-I/PH w/Crypto Engine (DM320006-C)
+
+See www.microchip.com for further information.
+
+Key features of the PIC32MZ Starter Kit include;
+
+  * On-board crystal or oscillator for precision microcontroller clocking
+    (24 MHz).
+  * 32 kHz oscillator for RTCC and Timer1 (optional).
+  * Three push button switches for user-defined inputs.
+  * Three user-defined indicator LEDs.
+  * USB Type A receptacle connectivity for PIC32 host-based applications.
+  * USB Type micro-AB receptacle for OTG and USB device connectivity for
+    PIC32 OTG/device-based applications.
+  * Daughter board connectors for flexible Ethernet PHY options.
+  * 50 MHz Ethernet PHY oscillator.
+  * External 4 GB SQI memory for expanded memory applications.
+  * PIC24FJ256GB106 USB microcontroller for on-board debugging.
+  * USB connectivity for on-board debugger communications.
+  * Regulated +3.3V power supply for powering the starter kit through USB or
+    expansion board.
+  * Connector for various expansion boards.
+
+The PIC32MZ starter kit comes complete with a LAN8740 PHY daughter board.

+
+On Board Debug Support
+======================
+
+  The starter kit includes a PIC24FJ256GB106 USB microcontroller that
+  provides debugger connectivity over USB. The PIC24FJ256GB106 is hard-wired
+  to the PIC32 device to provide protocol translation through the I/O pins
+  of the PIC24FJ256GB106 to the ICSP™ pins of the PIC32 device.
+
+  If MPLAB® REAL ICE™ or MPLAB ICD 3 is used with the starter kit,
+  disconnect the onboard debugger from the PIC32 device by removing the
+  jumper JP2. When the on-board debugger is required, replace the jumper
+  JP2. When the jumper JP2 is installed, pin 1 must be connected to pin 3
+  and pin 2 must be connected to pin 4.
+
+Creating Compatible NuttX HEX files
+===================================
+
+  Intel Hex Format Files:
+  -----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    #  Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.
+
+Serial Console

+
+LEDs and Buttons
+================
+
+  LEDs
+  ----
+  The PIC32MZ Ethernet Starter kit has 3 user LEDs labelled LED1-3 on the
+  board:
+
+  PIN  LED   Notes
+  ---  ----- -------------------------
+  RH0  LED1  High illuminates (RED)
+  RH1  LED3  High illuminates (YELLOW)
+  RH2  LED2  High illuminates (GREEN)
+
+  If CONFIG_ARCH_LEDS is defined, then NuttX will control these LEDs as
+  follows:
+
+                            ON                  OFF
+  ------------------------- ---- ---- ---- ---- ---- ----
+                            LED1 LED2 LED3 LED1 LED2 LED3
+  ------------------------- ---- ---- ---- ---- ---- ----
+  LED_STARTED            0  OFF  OFF  OFF  ---  ---  ---
+  LED_HEAPALLOCATE       1  ON   OFF  N/C  ---  ---  ---
+  LED_IRQSENABLED        2  OFF  ON   N/C  ---  ---  ---
+  LED_STACKCREATED       3  ON   ON   N/C  ---  ---  ---
+  LED_INIRQ              4  N/C  N/C  ON   N/C  N/C  OFF
+  LED_SIGNAL             4  N/C  N/C  ON   N/C  N/C  OFF
+  LED_ASSERTION          4  N/C  N/C  ON   N/C  N/C  OFF
+  LED_PANIC              5  ON   N/C  N/C  OFF  N/C  N/C
+
+  Buttons
+  -------
+
+  The PIC32MZ Ethernet Starter kit has 3 user push buttons labelled SW1-3 on
+  the board:
+
+  PIN   LED  Notes
+  ----  ---- -------------------------
+  RB12  SW1  Active-low
+  RB13  SW2  Active-low
+  RB14  SW3  Active-low
+
+  The switches do not have any debounce circuitry and require internal pull-
+  up resistors. When Idle, the switches are pulled high (+3.3V), and they
+  are grounded when pressed.
+
+Configurations
+==============
+
+Each PIC32MZ configuration is maintained in a sub-directory and can be
+selected as follow:
+
+    cd tools
+    ./configure.sh pic32mz-starterkit/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+
+    This is the NuttShell (NSH) using the NSH startup logic at
+    apps/examples/nsh.
+
+    NOTES:
+
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this 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.
+
+    2. Serial Output
+
+       The OS test produces all of its test output on the serial console.
+       This configuration has UART1 enabled as a serial console.  I have
+       been unable to get this UART work on the MEB.  But on the Expansion
+       I/O board, this maps to RX = J11 pin 41 and TX = J11 pin 43

+ * Name:  pic32mz_spiNselect, pic32mz_spiNstatus, and pic32mz_spiNcmddata
+ *
+ * Description:
+ *   These external functions must be provided by board-specific logic.  They are
+ *   implementations of the select, status, and cmddata methods of the SPI interface
+ *   defined by struct spi_ops_s (see include/nuttx/spi/spi.h). All other methods
+ *   including up_spiinitialize()) are provided by common PIC32MZ logic.  To use
+ *   this common SPI logic on your board:
+ *
+ *   1. Provide logic in pic32mz_boardinitialize() to configure SPI/SSP chip select
+ *      pins.
+ *   2. Provide pic32mz_spiNselect() and pic32mz_spiNstatus() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ *      pic32mz_spiNcmddata() functions in your board-specific logic.  These
+ *      functions will perform cmd/data selection operations using GPIOs in the way
+ *      your board is configured.
+ *   3. Add a call 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).
