2018-01-07: Added architecture support for the PIC32MZ2048EFH100 used on
|
||||||
|
the Flip&Click PIC32MZ board.
|
||||||
|
2018-01-08: Created the basic board configuration for the Mikroe
|

|
Flip&Click PIC32MZ board. No testing has yet been performed. I need

|
On Board Debug Support
|
||||||
|
======================
|
||||||
|
|
||||||
|
There are several debug options:
|
||||||
|
|
||||||
|
1. Using the Aduino IDE (chipKIT core). This is available on the USB-UART
|
||||||
|
port between the C and D MikroBUS sockets. Usage is described in the
|
||||||
|
Flip&Click User Manual.
|
||||||
|
|
||||||
|
2. Using the mikroC USB HID bootloader. This is is available on the USB
|
||||||
|
port between the A and B MikroBUS sockets. Usage is described in the
|
||||||
|
Flip&Click User Manual.
|
||||||
|
|
||||||
|
3. There is an undocumented and unpopulated PICKit3 connector between the
|
||||||
|
B and C mikroBUS sockets.
|
||||||
|
|
||||||
|
4. There is an undocumented and unpopulated mikroProg connector between
|
||||||
|
the A and D mikroBUS sockets.
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
export PATH=??? # 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
|
||||||
|
==============
|
||||||
|
|
||||||
|
[REVISIT: I am not sure if the USB VCOM ports are available to the
|
||||||
|
software. That is likely another serial port option].
|
||||||
|
|
||||||
|
Convenient U[S]ARTs that may be used as the Serial console include:
|
||||||
|
|
||||||
|
1) An Arduino Serial Shield. The RX and TX pins are available on the
|
||||||
|
Arduino connector D0 and D1 pins, respectively. These are connected
|
||||||
|
to UART5, UART5_RX and UART5_TX which are RD14 and RD15, respectively.
|
||||||
|
|
||||||
|
2) Mikroe Click Serial Shield. There are four Click bus connectors with
|
||||||
|
serial ports available as follows:
|
||||||
|
|
||||||
|
Click A: UART4 UART4_RX and UART4_TX which are RG9 and RE3, respectively.
|
||||||
|
Click B: UART3 UART3_RX and UART3_TX which are RF0 and RF1, respectively.
|
||||||
|
Click C: UART1 UART1_RX and UART1_TX which are RC1 and RE5, respectively.
|
||||||
|
Click D: UART2 UART2_RX and UART2_TX which are RC3 and RC2, respectively.
|
||||||
|
|
||||||
|
Other serial ports are probably available on the Arduino connector. I
|
||||||
|
will leave that as an exercise for the interested reader.
|
||||||
|
|
||||||
|
The outputs from these pins is 3.3V. You will need to connect RS232
|
||||||
|
transceiver to get the signals to RS232 levels (or connect to the
|
||||||
|
USB virtual COM port in the case of UART0).
|
||||||
|
|
||||||
|
LEDs and Buttons
|
||||||
|
================
|
||||||
|
|
||||||
|
LEDs
|
||||||
|
----
|
||||||
|
|
||||||
|
There are four LEDs on the top, red side of the board. Only
|
||||||
|
one can be controlled by software:
|
||||||
|
|
||||||
|
LED L - RB14 (SPI3_SCK)
|
||||||
|
|
||||||
|
There are also four LEDs on the back, white side of the board:
|
||||||
|
|
||||||
|
LED A - RA6
|
||||||
|
LED B - RA7
|
||||||
|
LED C - RE0
|
||||||
|
LED D - RE1
|
||||||
|
|
||||||
|
A high output value illuminates the LEDs.
|
||||||
|
|
||||||
|
These LEDs are available to the application and are all available to the
|
||||||
|
application unless CONFIG_ARCH_LEDS is defined. In that case, the usage
|
||||||
|
by the board port is defined in include/board.h and src/sam_autoleds.c.
|
||||||
|
The LEDs are used to encode OS-related events as follows:
|
||||||
|
|
||||||
|
SYMBOL MEANING LED STATE
|
||||||
|
L A B C D
|
||||||
|
---------------- ----------------------- --- --- --- --- ---
|
||||||
|
LED_STARTED NuttX has been started OFF ON OFF OFF OFF
|
||||||
|
LED_HEAPALLOCATE Heap has been allocated OFF OFF ON OFF OFF
|
||||||
|
LED_IRQSENABLED Interrupts enabled OFF OFF OFF ON OFF
|
||||||
|
LED_STACKCREATED Idle stack created OFF OFF OFF OFF ON
|
||||||
|
LED_INIRQ In an interrupt GLO N/C N/C N/C N/C
|
||||||
|
LED_SIGNAL In a signal handler GLO N/C N/C N/C N/C
|
||||||
|
LED_ASSERTION An assertion failed GLO N/C N/C N/C N/C
|
||||||
|
LED_PANIC The system has crashed 2Hz N/C N/C N/C N/C
|
||||||
|
LED_IDLE MCU is is sleep mode ---- Not used -----
|
||||||
|
|
||||||
|
Thus if LED L is glowing on and all other LEDs are off (except LED D which
|
||||||
|
was left on but is no longer controlled by NuttX and so may be in any
|
||||||
|
state), NuttX has successfully booted and is, apparently, running normally
|
||||||
|
and taking interrupts. If any of LEDs A-D are statically set, then NuttX
|
||||||
|
failed to boot and the LED indicates the initialization phase where the
|
||||||
|
failure occurred. If LED L is flashing at approximately 2Hz, then a fatal
|
||||||
|
error has been detected and the system has halted.
|
||||||
|
|
||||||
|
NOTE: After booting, LEDs A-D are no longer used by the system and may
|
||||||
|
be controlled the application.
|
||||||
|
|
||||||
|
Buttons
|
||||||
|
-------
|
||||||
|
|
||||||
|
The Flip&Click PIC32MZ has 2 user push buttons labeled T1 and T2 on the
|
||||||
|
white side of the board:

Configurations
|

|
==============
|
||||||
|
|
||||||
|
Information Common to All Configurations
|
||||||
|
----------------------------------------
|
||||||
|
|
||||||
|
1. Each PIC32MZ configuration is maintained in a sub-directory and can be
|
||||||
|
selected as follow:
|
||||||
|
|
||||||
|
tools/configure.sh flipnclick-pic32mz/<subdir>
|
||||||
|
|
||||||
|
Where typical options are -l to configure to build on Linux or -c to
|
||||||
|
configure for Cygwin under Linux. 'tools/configure.sh -h' will show
|
||||||
|
you all of the options.
|
||||||
|
|
||||||
|
Before building, make sure the PATH environment variable includes 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 directories listed in the
|
||||||
|
following paragraph.
|
||||||
|
|
||||||
|
2. These configurations 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
|
||||||
|
see additional README.txt files in the NuttX tools repository.
|
||||||
|
|
||||||
|
b. Execute 'make menuconfig' in the top-level nuttx in order to start
|
||||||
|
the reconfiguration process.

This is the NuttShell (NSH) using the NSH startup logic at
|
||||||
|
apps/examples/nsh.
|
||||||
|
|
||||||
|
NOTES:
|
||||||
|
|
||||||
|
1. Serial Console. UART 4 is configured as the Serial Console. This
|
||||||
|
assumes that you will be using a Mikroe RS-232 Click card in the
|
||||||
|
mikroBUS A slot. Other serial consoles may be selected by re-
|
||||||
|
configuring (see the section "Serial Consoles" above).
|
||||||
|
|
||||||
|
2. Toolchain
|
||||||
|
|
||||||
|
By default, the Pinguino MIPs tool chain is used. This toolchain
|
||||||
|
selection can easily be changed with 'make menuconfig'.
|
||||||
|
|
||||||
|
3. Default configuration: These are other things that you may want to
|
||||||
|
change in the configuration:
|
||||||
|
|
||||||
|
CONFIG_PIC32MZ_DEBUGGER_ENABLE=n : Debugger is disabled
|
||||||
|
CONFIG_PIC32MZ_TRACE_ENABLE=n : Trace is disabled
|
||||||
|
CONFIG_PIC32MZ_JTAG_ENABLE=n : JTAG is disabled

|
||||||
|
* meaning to NuttX; the meaning of the argument is a contract
|
||||||
|
* between the board-specific initalization logic and the
|
||||||
|
* matching application logic. The value cold be such things as a
|
||||||
|
* mode enumeration value, a set of DIP switch switch settings, a
|
||||||
|
* pointer to configuration data read from a file or serial FLASH,
|
||||||

* Returned Value:

* 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 pic32mz_spibus_initialize()) are provided by common PIC32MZ logic. To use
|
||||||
|
* this common SPI logic on your board:
|
||||||
|
*
|
||||||
|
* 1. Provide logic in pic32mz_boardinitialize() to configure SPI/SPI 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 pic32mz_spibus_initialize() in your low level application
|
||||||
|
* initialization logic
|
||||||
|
* 4. The handle returned by pic32mz_spibus_initialize() 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).
