=====================
|
|
|
|
This README file discusses the port of NuttX to the DTX1-4000L "Mirtoo" module.
|
|
This module uses MicroChip PIC32MX250F128D and the Dimitech DTX1-4000L EV-kit1
|
|
V2. See http://www.dimitech.com/ for further information.

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
|
|
|
|
Loading NuttX with ICD3
|
|
========================
|
|
|
|
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
|
|
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.
|
|
|

----------------------
|
|
|
|
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.

LED Usage
|
|
=========
|
|
|
|
The Mirtoo module has 2 user LEDs labeled LED0 and LED1 in the schematics:

--- ----- --------------------------------------------------------------
|
|
RC8 LED0 Grounded, high value illuminates
|
|
RC9 LED1 Grounded, high value illuminates
|
|
|
|
The Dimitech DTX1-4000L EV-kit1 supports 3 more LEDs, but there are not
|
|
controllable from software.
|
|
|
|
If CONFIG_ARCH_LEDS is defined, then NuttX will control these LEDs as
|
|
follows:
|
|
ON OFF
|
|
------------------------- ---- ---- ---- ----
|
|
LED0 LED1 LED0 LED1
|

|

LED_SIGNAL 4 ON N/C OFF N/C

|

LED_PANIC 4 ON N/C OFF N/C

UART Usage
|
|
==========
|
|
|
|
When mounted on the DTX1-4000L EV-kit1 board, serial output is avaiable through
|
|
an FT230X device via the FUNC0 and FUNC1 module outputs. If CONFIG_PIC32MX_UART2
|
|
is enabled, the src/up_boot will configure the UART2 pins as follows:
|
|
|
|

|
|
BOARD MODULE PIN SIGNAL NOTES

|
|
FT230X RXD FUNC0 RPB11 U2RX UART2 RX (Also PGEC2)
|
|
FT230X TXD FUNC1 RPB10 U2TX UART2 TX (Also PGED2)
|
|
|
|
However, since the FUNC0/1 pins are shared with the PGEC/D2, they cannot be used
|
|
for UART2 if you are also debugging with the ICD3. In that case, you may need
|
|
to switch to UART1.
|
|
|
|
If CONFIG_PIC32MX_UART1 is enabled, the src/up_boot will configure the UART
|
|
pins as follows. This will support communictions (via an external RS-232
|
|
driver) through X3 pins 4 and 5:

PIC32MX Configuration Options
|
|
=============================
|
|
|
|
General Architecture Settings:
|
|
|
|
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
|
|
be set to:
|
|
|
|
CONFIG_ARCH=mips
|
|
|
|
CONFIG_ARCH_family - For use in C code:
|
|
|
|
CONFIG_ARCH_MIPS=y
|
|
|
|
CONFIG_ARCH_architecture - For use in C code:
|
|
|
|

|
|
|
|
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
|
|
|
|
CONFIG_ARCH_CHIP=pic32mx
|
|
|
|
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
|
|
chip:
|
|
|
|
CONFIG_ARCH_CHIP_PIC32MX250F128D=y
|
|
|
|
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
|
hence, the board that supports the particular chip or SoC.
|
|
|
|
CONFIG_ARCH_BOARD=mirtoo
|
|
|
|
CONFIG_ARCH_BOARD_name - For use in C code
|
|
|
|
CONFIG_ARCH_BOARD_MIRTOO=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=0xa0000000
|
|
|
|
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.
