This README file discusses the port of NuttX to the "Advanced USB Storage
|
|
|
|
|
Demo Board," Model DB-DP11215, from Sure Electronics
|
|
|
|
|
(http://www.sureelectronics.net/). This board features the MicroChip
|
|
|
|
|
PIC32MX440F512H. See also http://www.sureelectronics.net/goods.php?id=1168
|
|
|

NOTE: I see that Sure Electronics shows both of these boards at end-of-Life
|
|
|
|
|
(EOL). So I assume that these boards will no longer be generally available.
|
|
|
|
|
This work should still be useful, however, for other PIC32MX4-based boards
|
|
|
|
|
(2012-5-27).

adapt to other toolchains by modifying the Make.defs file include in

each configuration.

An alternative, build-it-yourself toolchain is available here:
|
|
|
|
|
http://sourceforge.net/projects/microchipopen/ . These tools were
|
2012-06-22 23:28:15 +02:00
|
|
|
last updated circa 2010. NOTE: C++ support still not available
|
|
|
|
|
in this toolchain.

Building MicrochipOpen (on Linux)
|
|
|
|
|
|
|
|
|
|
1) Get the build script from this location:
|
2012-06-22 20:58:24 +02:00
|
|
|
|
|
|
|
|
http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
|
|
|
|
|
|
2012-06-22 20:35:25 +02:00
|
|
|
2) Build the code using the build script, for example:
|
2012-06-22 20:58:24 +02:00
|
|
|
|
|
|
|
|
./build.sh -b v105_freeze
|
|
|
|
|
|
|
|
|
|
This will check out the selected branch and build the tools.
|
|
|
|
|
|
|
|
|
|
3) Binaries will then be available in a subdirectory with a name something like
|
|
|
|
|
pic32-v105-freeze-20120622/install-image/bin (depending on the current data
|
|
|
|
|
and the branch that you selected.
|
|
|
|
|
|
|
|
|
|
Note that the tools will have the prefix, mypic32- so, for example, the
|
|
|
|
|
compiler will be called mypic32-gcc.

Penguino mips-elf Toolchain
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
Another option is the mips-elf toolchain used with the Penguino project. This
|
|
|
|
|
is a relatively current mips-elf GCC and should provide free C++ support as
|
|
|
|
|
well. This toolchain can be downloded from the Penguino website:
|
|
|
|
|
http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
|
|
|
|
|
information about using the Penguino mips-elf toolchain in this thread:
|
|
|
|
|
http://tech.groups.yahoo.com/group/nuttx/message/1821
|
|
|
|
|
|
|
|
|
|
See also configs/mirtoo/README.txt. There is an experimental (untested)
|
|
|
|
|
configuration for the Mirtoo platform in that directory.

MPLAB/C32 vs MPLABX/X32
|
|
|
|
|
-----------------------
|
|
|
|
|
|
|
|
|
|
It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
|
|
|
|
|
it with MPLABX and XC32. At present, the XC32 toolchain is *not* compatible
|
|
|
|
|
with the NuttX build scripts. Here are some of the issues that I see when trying
|
|
|
|
|
to build with XC32:
|
|
|
|
|
|
|
|
|
|
1) Make.def changes: You have to change the tool prefix:
|
|
|
|
|
|
|
|
|
|
CROSSDEV=xc32-
|
|
|
|
|
|
|
|
|
|
2) debug.ld/release.ld: The like expect some things that are not present in
|
|
|
|
|
the current linker scripts (or are expected with different names). Here
|
|
|
|
|
are some partial fixes:
|
|
|
|
|
|
|
|
|
|
Rename: kseg0_progmem to kseg0_program_mem
|
|
|
|
|
Rename: kseg1_datamem to kseg1_data_mem
|
2011-07-03 18:31:10 +02:00
|
|
|
|
2012-06-22 20:35:25 +02:00
|
|
|
Even then, there are more warnings from the linker and some undefined symbols
|
|
|
|
|
for non-NuttX code that resides in the unused Microchip libraries. See this
|
|
|
|
|
email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
|
|
|
|
|
information. You will have to solve at least this undefined symbol problem if
|
|
|
|
|
you want to used the XC32 toolchain.

Windows Native Toolchains
|
2012-06-22 20:35:25 +02:00
|
|
|
-------------------------
|
2013-05-27 19:39:13 +02:00
|
|
|
|
2011-07-03 18:31:10 +02:00
|
|
|
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
|
2011-10-13 19:49:11 +02:00
|
|
|
a file in a "linked" directory and find that your changes had no effect.
|
2011-07-03 18:31:10 +02:00
|
|
|
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.

Loading NuttX with PICkit2
|
|
|
|
|
==========================
|
|
|
|
|
|
|
|
|
|
NOTE: You need a PICKit3 if you plan to use the MPLAB debugger! The PICKit2
|
2011-10-12 04:32:57 +02:00
|
|
|
can, however, still be used to load programs. Instructions for the PICKit3
|
2011-07-03 18:31:10 +02:00
|
|
|
are similar.

Intel Hex Forma Files:
|
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
|
|
When NuttX is built it will produce two files in the top-level NuttX
|
|
|
|
|
directory:
|
|
|
|
|
|
|
|
|
|
1) nuttx - This is an ELF file, and
|
2012-02-27 20:50:35 +01:00
|
|
|
2) nuttx.hex - This is an Intel Hex format file. This is controlled by
|
2011-07-03 18:31:10 +02:00
|
|
|
the setting CONFIG_INTELHEX_BINARY in the .config file.
|
|
|
|
|
|
2012-02-27 20:50:35 +01:00
|
|
|
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.
|
2011-07-03 18:31:10 +02:00
|
|
|
|
2012-06-20 21:29:20 +02:00
|
|
|
tools/pic32mx/mkpichex:
|
|
|
|
|
----------------------
|
2011-07-03 18:31:10 +02:00
|
|
|
|
2012-06-20 21:29:20 +02:00
|
|
|
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:
|
2011-07-03 18:31:10 +02:00
|
|
|
|
2012-06-20 21:29:20 +02:00
|
|
|
cd tools/pic32mx
|
2011-07-03 18:31:10 +02:00
|
|
|
make
|
|
|
|
|
|
|
|
|
|
Now you will have an excecutable file call mkpichex (or mkpichex.exe on
|
2012-02-27 20:50:35 +01:00
|
|
|
Cygwin). This program will take the nutt.hex file as an input, it will
|
2011-07-03 18:31:10 +02:00
|
|
|
convert all of the KSEG0 and KSEG1 addresses to physical address, and
|
2012-02-27 20:50:35 +01:00
|
|
|
it will write the modified file, replacing the original nuttx.hex.
|
2011-07-03 18:31:10 +02:00
|
|
|
|
|
|
|
|
To use this file, you need to do the following things:
|
|
|
|
|
|
|
|
|
|
. ./setenv.sh # Source setenv.sh. Among other this, this script
|
2012-06-20 21:29:20 +02:00
|
|
|
# will add the NuttX tools/pic32mx directory to your
|
2011-07-03 18:31:10 +02:00
|
|
|
# PATH variable
|
2012-02-27 20:50:35 +01:00
|
|
|
make # Build nuttx and nuttx.hex
|
|
|
|
|
mkpichex $PWD # Convert addresses in nuttx.hex. $PWD is the path
|
2011-07-03 18:31:10 +02:00
|
|
|
# to the top-level build directory. It is the only
|
|
|
|
|
# required input to mkpichex.
|
|
|
|

NOTES:
|
2013-07-05 19:45:17 +02:00
|
|
|
2013-05-27: The LCD1602 has been verified on the DB-DP11212 using
|
|
|
|
|
this configuration. It has not been used with the usbnsh configuration
|
|
|
|
|
or with the DB-11112 board. It looks to me like the connection to the
|
|
|
|
|
LCD1602 is identical on the DB-11112 and so I would expect that to work.
|
|
|
|
|
|
|
|
|
|
At this point in time, testing of the SLCD is very limited because
|
|
|
|
|
there is not much in apps/examples/slcd. Basically driver with a working
|
|
|
|
|
test setup and ready to be tested and debugged.

|
|
|
This is another NSH example. If differs from the 'nsh' configuration
|
|
|
|
|
above in that this configurations uses a USB serial device for console
|
|
|
|
|
I/O. This configuration was created to support the "DB-DP11212 PIC32
|
|
|
|
|
General Purpose Demo Board" which has no easily accessible serial port.
|
|
|
|
|
However, as of this writing, the configuration has set for the
|
|
|
|
|
"DB_DP11215 PIC32 Storage Demo Board" and has only be testing on that
|
|
|
|
|
board.

Notes.
|
|
|
|
|
-----
|
|
|
|
|
1. By default, this configuration uses an older Microchip C32 toolchain
|
|
|
|
|
for Windows (the newer ones seem to be incompatible) and builds under
|
|
|
|
|
Cygwin (or probably MSYS). That can easily be reconfigured, of course.
|
|
|
|
|
|
|
|
|
|
Build Setup:
|
|
|
|
|
CONFIG_HOST_WINDOWS=y : Builds under Windows
|
|
|
|
|
CONFIG_WINDOWS_CYGWIN=y : Using Cygwin
|
|
|
|
|
|
|
|
|
|
System Type:
|
|
|
|
|
CONFIG_MIPS32_TOOLCHAIN_MICROCHIPW_LITE=y : Older C32 toolchain
|
|
|
|
|
|
|
|
|
|
2. Comparison to nsh
|
|
|
|
|
|
|
|
|
|
Below summarizes the key configuration differences between the 'nsh'
|
|
|
|
|
and the 'upnsh' configurations:
|
|
|
|
|
|
|
|
|
|
CONFIG_USBDEV=y : NuttX USB device support is enabled
|
|
|
|
|
CONFIG_PIC32MX_USBDEV=y : The PIC32MX USB device driver is built
|
2013-05-27 22:10:34 +02:00
|
|
|
CONFIG_DEV_CONSOLE=n : /dev/console does not exist on power up
|
2013-05-27 00:44:53 +02:00
|
|
|
CONFIG_UART1_SERIAL_CONSOLE=n : There is no serial console
|
|
|
|
|
CONFIG_UART2_SERIAL_CONSOLE=n :
|
|
|
|
|
CONFIG_CDCACM=y : The CDC/ACM serial device class is enabled
|
|
|
|
|
CONFIG_CDCACM_CONSOLE=y : The CDC/ACM serial device is the console
|
|
|
|
|
|
2013-05-27 22:10:34 +02:00
|
|
|
3. Using the Prolifics PL2303 Emulation
|
2013-05-27 00:44:53 +02:00
|
|
|
|
|
|
|
|
You could also use the non-standard PL2303 serial device instead of
|
|
|
|
|
the standard CDC/ACM serial device by changing:
|
|
|
|
|
|
2013-05-29 18:26:00 +02:00
|
|
|
Drivers->USB Device Driver Support
|
|
|
|
|
CONFIG_CDCACM=n : Disable the CDC/ACM serial device class
|
|
|
|
|
CONFIG_CDCACM_CONSOLE=n : The CDC/ACM serial device is NOT the console
|
|
|
|
|
CONFIG_PL2303=y : The Prolifics PL2303 emulation is enabled
|
|
|
|
|
CONFIG_PL2303_CONSOLE=y : The PL2303 serial device is the console
|
2013-05-27 00:44:53 +02:00
|
|
|
|
|
|
|
|
Why would you want to use a non-standard USB serial driver? You might
|
|
|
|
|
to use the PL2303 driver with a Windows host because it should
|
|
|
|
|
automatically install the PL2303 driver (you might have to go through
|
|
|
|
|
some effort to get Windows to recognize the CDC/ACM device).
|
2013-05-27 22:10:34 +02:00
|
|
|
|
|
|
|
|
4. Since this configuration is current set for the "DB_DP11215 PIC32
|
2013-05-29 18:26:00 +02:00
|
|
|
Storage Demo Board," UART2 is available and is configured to used as
|
2013-05-27 22:10:34 +02:00
|
|
|
the SYSLOG device. That means that all debug output will be directed
|
2013-05-29 18:26:00 +02:00
|
|
|
out UART2. Debug output is not enabled by default, however, so these
|
2013-05-27 22:10:34 +02:00
|
|
|
settings do nothing until you enable debug ouput.
|
|
|
|
|
|
|
|
|
|
Device Drivers -> System Logging Device Options:
|
|
|
|
|
CONFIG_SYSLOG=y : Configure SYSLOG output
|
|

|
|
|
|

|
|
|
|
|
|
|
|
|
|
System Type -> PIC32MX Peripheral Support:
|
|
|
|
|
CONFIG_PIC32MX_UART2=y : Enable UART2
|
|
|
|
|
|
|
|
|
|
Device Drivers -> Serial Driver Support:
|
|
|
|
|
CONFIG_UART2_2STOP=0 : UART2 configuration
|
|
|
|
|
CONFIG_UART2_BAUD=115200
|
|
|
|
|
CONFIG_UART2_BITS=8
|
|
|
|
|
CONFIG_UART2_PARITY=0
|
|
|
|
|
CONFIG_UART2_RXBUFSIZE=64
|
|
|
|
|
CONFIG_UART2_TXBUFSIZE=64
|
|
|
|
|
|
2013-05-28 21:36:01 +02:00
|
|
|
NOTE: Using the SYSLOG to get debug output has limitations. Among
|
|
|
|
|
those are that you cannot get debug output from interrupt handlers.
|
|
|
|
|
So, in particularly, debug output is not a useful way to debug the
|
|
|
|
|
USB device controller driver. Instead, use the USB monitor with
|
|
|
|
|
USB debug off and USB trance on (see below).
|
2013-05-27 22:10:34 +02:00
|
|
|
|
2013-05-28 21:36:01 +02:00
|
|
|
5. Enabling USB monitor SYSLOG output. If tracing is enabled, the USB
|
2013-05-27 22:10:34 +02:00
|
|
|
device will save encoded trace output in in-memory buffer; if the
|
|
|
|
|
USB monitor is enabled, that trace buffer will be periodically
|
2013-05-28 21:36:01 +02:00
|
|
|
emptied and dumped to the system logging device (UART2 in this
|
2013-06-26 18:54:12 +02:00
|
|
|
configuration):

2013-05-27 22:10:34 +02:00
|
|

CONFIG_USBDEV_TRACE=y : Enable USB trace feature
|
2013-05-28 21:36:01 +02:00
|
|
|
CONFIG_USBDEV_TRACE_NRECORDS=256 : Buffer 128 records in memory

|
|
|
NOTE: USB debug output also be enabled in this case. Both will appear
|
|
|
|
|
on the serial SYSLOG output. However, the debug output will be
|
|
|
|
|
asynchronous with the trace output and, hence, difficult to interpret.

6. If you want to try this configuration on the DB-DP11212 PIC32 General
|
|
|
|
|
Purpose Demo Board", here are the changes that you should make:
|
|
|
|
|
|
|
|
|
|
Board Configuration:
|
|
|
|
|
CONFIG_ARCH_DBDP11215=n : Disable the DB-DP11215
|
|
|
|
|
CONFIG_ARCH_DBDP11212=y : Enable the DB-DP11212
|
2013-07-03 19:39:54 +02:00
|
|
|
CONFIG_ARCH_LEDS=n : The DB-DP11212 has no LEDs
|
2013-05-28 21:36:01 +02:00
|
|
|
|
|
|
|
|
System Type -> PIC32MX Peripheral Support:
|
|
|
|
|
CONFIG_PIC32MX_UART2=n : Disable UART2
|
|
|
|
|
|
2013-06-26 18:54:12 +02:00
|
|
|
The SYSLOG output on UART2 cannot by used. You have two choices,
|
|
|
|
|
first, you can simply disable the SYSLOG device. Then 1) debug
|
|
|
|
|
output will come the USB console, and 2) all debug output prior
|
|
|
|
|
to connecting the USB console will be lost:
|
|
|
|
|
|
2013-05-28 21:36:01 +02:00
|
|
|
Device Drivers -> System Logging Device Options:
|
|
|
|
|
CONFIG_SYSLOG=n : Disable SYSLOG output
|
2013-06-26 18:54:12 +02:00
|
|
|
|
|
|
|
|
The second options is to configure a RAM SYLOG device. This is
|
|
|
|
|
a circular buffer that accumulated debug output in memory. The
|
|
|
|
|
contents of the circular buffer can be dumped from the NSH command
|
|
|
|
|
line using the 'dmesg' command.
|
|
|
|
|
|
|
|
|
|
Device Drivers -> System Logging Device Options:
|
|
|
|
|
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.
|
|
|
|
|
|
2013-07-03 19:39:54 +02:00
|
|
|
Logging is currently can be set up to use any amount of memory (here 8KB):
|
2013-06-26 18:54:12 +02:00
|
|
|
|
|
|
|
|
CONFIG_RAMLOG_CONSOLE_BUFSIZE=8192
|
|
|
|
|
|
2013-07-05 19:45:17 +02:00
|
|
|
STATUS:
|
|
|
|
|
2013-7-4: This configuration was last verified.
|
|
|
|
|
|
2013-06-26 18:54:12 +02:00
|
|
|
7. See the notes for the nsh configuration. Most also apply to the usbnsh
|
2013-07-05 19:45:17 +02:00
|
|
|
configuration as well.
