Toolchains
|
||||
==========
|
||||
|
||||
I am using the free, LITE version of the PIC32MX toolchain available
|
||||
for download from the microchip.com web site. I am using the Windows
|
||||
version. The MicroChip toolchain is the only toolchaing currently
|
||||
supported in these configurations, but it should be a simple matter to
|
||||
adapt to other toolchains by modifying the Make.defs file include in
|
||||
each configuration.
|
||||
|
||||
Toolchain Options:
|
||||
|
||||
CONFIG_PIC32MX_MICROCHIPW - MicroChip full toolchain for Windows
|
||||
CONFIG_PIC32MX_MICROCHIPL - MicroChip full toolchain for Linux
|
||||
CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip LITE toolchain for Windows
|
||||
CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip LITE toolchain for Linux
|
||||
|
||||
Windows Native Toolchains
|
||||
|
||||
NOTE: There are several limitations to using a Windows based toolchain in a
|
||||
Cygwin environment. The three biggest are:
|
||||
|
||||
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
|
||||
performed automatically in the Cygwin makefiles using the 'cygpath' utility
|
||||
but you might easily find some new path problems. If so, check out 'cygpath -w'
|
||||
|
||||
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links
|
||||
are used in Nuttx (e.g., include/arch). The make system works around these
|
||||
problems for the Windows tools by copying directories instead of linking them.
|
||||
But this can also cause some confusion for you: For example, you may edit
|
||||
a file in a "linked" directory and find that your changes had no effect.
|
||||
That is because you are building the copy of the file in the "fake" symbolic
|
||||
directory. If you use a Windows toolchain, you should get in the habit of
|
||||
making like this:
|
||||
|
||||
make clean_context all
|
||||
|
||||
An alias in your .bashrc file might make that less painful.
|
||||
|
||||
3. Dependencies are not made when using Windows versions of the GCC. This is
|
||||
because the dependencies are generated using Windows pathes which do not
|
||||
work with the Cygwin make.
|
||||
|
||||
Support has been added for making dependencies with the windows-native toolchains.
|
||||
That support can be enabled by modifying your Make.defs file as follows:
|
||||
|
||||
- MKDEP = $(TOPDIR)/tools/mknulldeps.sh
|
||||
+ MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
|
||||
|
||||
If you have problems with the dependency build (for example, if you are not
|
||||
building on C:), then you may need to modify tools/mkdeps.sh
|
||||
|
||||
Powering the Board

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/mkpichex:
|
||||
---------------
|
||||
|
||||
There is a simple tool in the configs/pic32mx7mmb/tools directory
|
||||
that can be used to solve both issues with the nuttx.hex file. But,
|
||||
first, you must build the the tools:
|
||||
|
||||
cd configs/pic32mx7mmb/tools
|
||||
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 configs/pic32mx7mmb/tools 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.

CONFIG_ARCH=mips
|
||||
|
||||
CONFIG_ARCH_family - For use in C code:
|
||||
|
||||

|
||||
chip:
|
||||
|
||||
CONFIG_ARCH_CHIP_PIC32MX795F512L=y
|
||||
|
||||
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
||||
hence, the board that supports the particular chip or SoC.
|
||||
|
||||
CONFIG_ARCH_BOARD=pic32mx7mmb
|
||||
|
||||
CONFIG_ARCH_BOARD_name - For use in C code
|
||||
|
||||
CONFIG_ARCH_BOARD_PIC32MX7MMB=y
|
||||
|
||||
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 DRAM (CPU SRAM in this case):
|
||||
|
||||
CONFIG_DRAM_SIZE=(32*1024) (32Kb)
|
||||
|
||||
There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
|
||||
|
||||
CONFIG_DRAM_START - The start address of installed DRAM
|
||||
|
||||
CONFIG_DRAM_START=0x10000000
|
||||
|
||||
CONFIG_DRAM_END - Last address+1 of installed RAM
|
||||
|
||||
CONFIG_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
|
||||
|
||||
CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
|
||||
|
||||
CONFIG_ARCH_IRQPRIO=y
|
||||
|
||||
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_LEDS - Use LEDs to show state. Unique to board architecture.
|
||||
|
||||
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.

|
||||
|
||||
USB Configuations.
|
||||
-----------------
|
||||
Several USB device configurations can be enabled and included
|
||||
as NSH built-in built in functions.
|
||||
|
||||
To use USB device, connect the starter kit to the host using a cable
|
||||
with a Type-B micro-plug to the starter kit’s micro-A/B port J5, located
|
||||
on the bottom side of the starter kit. The other end of the cable
|
||||
must have a Type-A plug. Connect it to a USB host. Jumper JP2 should be
|
||||
removed.
|
||||
|
||||
All USB device configurations require the following basic setup in
|
||||
your NuttX configuration file to enable USB device support:
|
||||
|
||||
CONFIG_USBDEV=y : Enable basic USB device support
|
||||
CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support
|
||||
|
||||
examples/usbterm - This option can be enabled by uncommenting
|
||||
the following line in the appconfig file:
|
||||
|
||||
CONFIGURED_APPS += examples/usbterm
|
||||
|
||||
And by enabling one of the USB serial devices:
|
||||
|
||||
CONFIG_PL2303=y : Enable the Prolifics PL2303 emulation
|
||||
CONFIG_CDCACM=y : or the CDC/ACM serial driver (not both)
|
||||
|
||||
examples/cdcacm - The examples/cdcacm program can be included as an
|
||||
function by uncommenting the following line in the appconfig file:
|
||||
|
||||
CONFIGURED_APPS += examples/cdcacm
|
||||
|
||||
and defining the following in your .config file:
|
||||
|
||||
CONFIG_CDCACM=y : Enable the CDCACM device
|
||||
|
||||
examples/usbstorage - There are some hooks in the appconfig file
|
||||
to enable the USB mass storage device. However, this device cannot
|
||||
work until support for the SD card is also incorporated.
|
||||
|
||||
Networking Configuations.
|
||||
-------------------------
|
||||
Several Networking configurations can be enabled and included
|
||||
as NSH built-in built in functions. The following additional
|
||||
configuration settings are required:
|
||||
|
||||
CONFIG_NET=y : Enable networking support
|
||||
CONFIG_PIC32MX_ETHERNET=y : Enable the PIC32 Ethernet driver
|
||||
CONFIG_NSH_TELNET=y : Enable the Telnet NSH console (optional)
|
||||
|
||||
NOTES:
|
||||
1. This logic will assume that a network is connected. During its
|
||||
initialization, it will try to negotiate the link speed. If you have
|
||||
no network connected when you reset the board, there will be a long
|
||||
delay (maybe 30 seconds?) before anything happens. That is the timeout
|
||||
before the networking finally gives up and decides that no network is
|
||||
available.
|
||||
|
||||
2. This example can support an FTP client. In order to build in FTP client
|
||||
support simply uncomment the following lines in the appconfig file (before
|
||||
configuring) or in the apps/.config file (after configuring):
|
||||
|
||||
#CONFIGURED_APPS += netutils/ftpc
|
||||
#CONFIGURED_APPS += examples/ftpc
|
||||
|
||||
3. This example can support an FTP server. In order to build in FTP server
|
||||
support simply uncomment the following lines in the appconfig file (before
|
||||
configuring) or in the apps/.config file (after configuring):
|
||||
|
||||
#CONFIGURED_APPS += netutils/ftpd
|
||||
#CONFIGURED_APPS += examples/ftpd
|
||||
|
||||
And enable poll() support in the NuttX configuration file:
|
||||
|
||||
CONFIG_DISABLE_POLL=n

This is an alternative NSH configuration. Without the Expansion I/O board,
|
||||
there is no way to connect a serial console. This NSH alternative supports
|
||||
only a Telnet console. The nsh2 differs from the nsh configuration in the
|
||||
following ways:
|
||||
|
||||
1. Networking is enabled:
|
||||
|
||||
CONFIG_NET=y : Enable networking support
|
||||
CONFIG_PIC32MX_ETHERNET=y : Enable the PIC32 Ethernet driver
|
||||
CONFIG_NSH_CONSOLE=n : Disable NSH serial console
|
||||
CONFIG_NSH_TELNET=y : Enable the Telnet NSH console
|
||||
|
||||
See apps/nshlib/README.txt for other NSH networking-related configuration
|
||||
settings.
|
||||
|
||||
2. UART1 is disabled
|
||||
|
||||
CONFIG_PIC32MX_UART1=n : UART1 is disabled (as well as other UARTs)
|
||||
CONFIG_UART1_SERIAL_CONSOLE=n : There is no serial console
|
||||
|
||||
3. The RAM log is enabled"
|
||||
|
||||
CONFIG_SYSLOG=y : Enables the System Logging feature.
|
||||
CONFIG_RAMLOG=y : Enable the RAM-based logging feature.
|
||||
CONFIG_RAMLOG_CONSOLE=n : (there is no default console device)
|
||||
CONFIG_RAMLOG_SYSLOG=y : This enables the RAM-based logger as the
|
||||
system logger.
|
||||
|
||||
Logging is currently set up to use 16Kb of memory:
|
||||
|
||||
CONFIG_RAMLOG_CONSOLE_BUFSIZE=16384
|
||||
|
||||
There are a few other configuration differences as necessary to support
|
||||
this different device configuration. Just the do the 'diff' if you are
|
||||
curious.
|
||||
|
||||
NOTES:
|
||||
See the notes for the nsh configuration. Most also apply to the nsh2
|
||||
configuration.

|
||||
Using a RAM disk and the USB MSC device with nsh and nsh2
|
||||
---------------------------------------------------------
|
||||
Here is an experimental change to either examples/nsh or examples/nsh2
|
||||
that will create a RAM disk and attempt to export that RAM disk as a
|
||||
USB mass storage device.
|
||||
|
||||
1. Changes to nuttx/.config
|
||||
|
||||
a) Enable support for the PIC32 USB device
|
||||
|
||||
-CONFIG_PIC32MX_USBDEV=n
|
||||
+CONFIG_PIC32MX_USBDEV=y
|
||||
|
||||
b) Enable NuttX USB device support
|
||||
|
||||
-CONFIG_USBDEV=n
|
||||
+CONFIG_USBDEV=y
|
||||
|
||||
c) Enable the USB MSC class driver
|
||||
|
||||
-CONFIG_USBMSC=n
|
||||
+CONFIG_USBMSC=y
|
||||
|
||||
d) Use a RAM disk (instead of an SD card) as the USB MSC logical unit:
|
||||
|
||||
-CONFIG_EXAMPLES_USBMSC_DEVPATH1="/dev/mmcsd0"
|
||||
+CONFIG_EXAMPLES_USBMSC_DEVPATH1="/dev/ram0"
|
||||
|
||||
2. Changes to nuttx/.config.
|
||||
|
||||
a) Enable building of the examples/usbstorage:
|
||||
|
||||
-# CONFIGURED_APPS += examples/usbstorage
|
||||
+ CONFIGURED_APPS += examples/usbstorage
|
||||
|
||||
3. When NSH first comes up, you must manually create the RAM disk
|
||||
before exporting it:
|
||||
|
||||
a) Create a 64Kb RAM disk at /dev/ram0:
|
||||
|
||||
nsh> mkrd -s 512 128
|
||||
|
||||
b) Put a FAT file system on the RAM disk:
|
||||
|
||||
nsh> mkfatfs /dev/ram0
|
||||
|
||||
b) Now the 'msconn' command will connect to the host and
|
||||
export /dev/ram0 as the USB logical unit:
|
||||
|
||||
nsh> msconn
|
||||
|
||||
NOTE: This modification should be considered experimental. IN the
|
||||
little testing I have done with it, it appears functional. But the
|
||||
logic has not been stressed and there could still be lurking issues.
|
||||
|
||||
Update. The following was added to the top-level TODO list:
|
||||
|
||||
Title: PIC32 USB DRIVER DOES NOT WORK WITH MASS STORAGE CLASS
|
||||
Description: The PIC32 USB driver either crashes or hangs when used with
|
||||
the mass storage class when trying to write files to the target
|
||||
storage device. This usually works with debug on, but does not
|
||||
work with debug OFF (implying some race condition?)
|
||||
|
||||
Here are some details of what I see in debugging:
|
||||
|
||||
1. The USB MSC device completes processing of a read request
|
||||
and returns the read request to the driver.
|
||||
2. Before the MSC device can even begin the wait for the next
|
||||
driver, many packets come in at interrupt level. The MSC
|
||||
device goes to sleep (on pthread_cond_wait) with all of the
|
||||
read buffers ready (16 in my test case).
|
||||
3. The pthread_cond_wait() does not wake up. This implies
|
||||
a problem with pthread_con_wait(?). But in other cases,
|
||||
the MSC device does wake up, but then immediately crashes
|
||||
because its stack is bad.
|
||||
4. If I force the pthread_cond_wait to wake up (by using
|
||||
pthread_cond_timedwait instead), then the thread wakes
|
||||
up and crashes with a bad stack.
|
||||
|
||||
So far, I have no clue why this is failing.
|
||||

*
|

* 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.h). All other methods
|
||||
* including up_spiinitialize()) are provided by common PIC32MX logic. To use
|
||||
* this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in pic32mx_boardinitialize() to configure SPI/SSP chip select
|
||||
* pins.
|
||||
* 2. Provide pic32mx_spiNselect() and pic32mx_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
|
||||
* pic32mx_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).

* current on D+ or D- when the host/hub is not actively powering the Vbus line.

* A 5V tolerant I/O pin can be connected to Vbus (through a resistor), and

* 04, Extended Linear Address Record, allowing for fully 32 bit addressing.
|

* The address field is 0000, the byte count is 02. The two data bytes
|

* represent the upper 16 bits of the 32 bit address, when combined with

* the address of the 00 type record.
|

* 05, Start Linear Address Record. The address field is 0000, the byte
|

* count is 04. The 4 data bytes represent the 32-bit value loaded into
