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
|

||||
|

To be provided
|
||||
|
||||
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

|
||||
|
||||
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

* 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).
