Development Environment
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Either Linux or Cygwin on Windows can be used for the development environment.
|
||||
The source has been built only using the GNU toolchain (see below). Other
|
||||
toolchains will likely cause problems.
|
||||
|
||||
GNU Toolchain Options
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The NuttX make system has been modified to support the following different
|
||||
toolchain options.
|
||||
|
||||
1. The CodeSourcery GNU toolchain,
|
||||
2. The devkitARM GNU toolchain,
|
||||
3. Raisonance GNU toolchain, or
|
||||
4. The NuttX buildroot Toolchain (see below).
|
||||
|
||||
All testing has been conducted using the NuttX buildroot toolchain. However,
|
||||
the make system is setup to default to use the devkitARM toolchain. To use
|
||||
the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
|
||||
add one of the following configuration options to your .config (or defconfig)
|
||||
file:
|
||||
|
||||
CONFIG_LPC31XX_CODESOURCERYW=y : CodeSourcery under Windows
|
||||
CONFIG_LPC31XX_CODESOURCERYL=y : CodeSourcery under Linux
|
||||
CONFIG_LPC31XX_DEVKITARM=y : devkitARM under Windows
|
||||
CONFIG_LPC31XX_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
||||
|
||||
If you are not using CONFIG_LPC31XX_BUILDROOT, then you may also have to modify
|
||||
the PATH in the setenv.h file if your make cannot find the tools.
|
||||
|
||||
NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
|
||||
Windows native toolchains. The CodeSourcey (for Linux) and NuttX buildroot
|
||||
toolchains are Cygwin and/or Linux native toolchains. 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
|
||||
|
||||
NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
|
||||
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
|
||||
-Os.
|
||||
|
||||
NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that
|
||||
the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
|
||||
path or will get the wrong version of make.
|
||||
|
||||
IDEs
|
||||
^^^^
|
||||
|
||||
NuttX is built using command-line make. It can be used with an IDE, but some
|
||||
effort will be required to create the project (There is a simple RIDE project
|
||||
in the RIDE subdirectory).
|
||||
|
||||
Makefile Build
|
||||
--------------
|
||||
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
|
||||
simply use the NuttX makefile to build the system. That is almost for free
|
||||
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
|
||||
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
|
||||
there is a lot of help on the internet).
|
||||
|
||||
Native Build
|
||||
------------
|
||||
Here are a few tips before you start that effort:
|
||||
|
||||
1) Select the toolchain that you will be using in your .config file
|
||||
2) Start the NuttX build at least one time from the Cygwin command line
|
||||
before trying to create your project. This is necessary to create
|
||||
certain auto-generated files and directories that will be needed.
|
||||
3) Set up include pathes: You will need include/, arch/arm/src/lpc31xx,
|
||||
arch/arm/src/common, arch/arm/src/arm, and sched/.
|
||||
4) All assembly files need to have the definition option -D __ASSEMBLY__
|
||||
on the command line.
|
||||
|
||||
Startup files will probably cause you some headaches. The NuttX startup file
|
||||
is arch/arm/src/lpc31xx/lpc31_vectors.S. With RIDE, I have to build NuttX
|
||||
one time from the Cygwin command line in order to obtain the pre-built
|
||||
startup object needed by RIDE.
|
||||
|
||||
NuttX buildroot Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
|
||||
be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
|
||||
different from the default in your PATH variable).
|
||||
|
||||
If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
|
||||
SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||
|
||||
cd tools
|
||||
./configure.sh ea3152/<sub-dir>
|
||||
|
||||
2. Download the latest buildroot package into <some-dir>
|
||||
|
||||
3. unpack the buildroot tarball. The resulting directory may
|
||||
have versioning information on it like buildroot-x.y.z. If so,
|
||||
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
|
||||
|
||||
4. cd <some-dir>/buildroot
|
||||
|
||||
5. cp configs/arm926t-defconfig-4.2.4 .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Edit setenv.h, if necessary, so that the PATH variable includes
|
||||
the path to the newly built binaries.
|
||||
|
||||
See the file configs/README.txt in the buildroot source tree. That has more
|
||||
detailed PLUS some special instructions that you will need to follow if you are
|
||||
building a Cortex-M3 toolchain for Cygwin under Windows.
|
||||
|
||||
Boot Sequence
|
||||
^^^^^^^^^^^^^
|
||||
LPC313x has on chip bootrom which loads properly formatted images from multiple
|
||||
sources into SRAM. These sources include including SPI Flash, NOR Flash, UART,
|
||||
USB, SD Card, and NAND Flash.
|
||||
|
||||
In all configurations, NuttX is loaded directly into ISRAM. NuttX is linked
|
||||
to execute from ISRAM, regardless of the boot source.
|
||||
|
||||
Image Format
|
||||
^^^^^^^^^^^^
|
||||
|
||||
In order to use the bootrom bootloader, a special header must be added to the
|
||||
beginning of the binary image that includes information about the binary (things
|
||||
like the entry point, the size, and CRC's to verify the image.
|
||||
|
||||
NXP provides a Windows program to append such a header to the binary image.
|
||||
However, (1) that program won't run under Linux, and (2) when I try it under
|
||||
WinXP, Symantec immediately claims that the program is misbehaving and deletes
|
||||
it!
|
||||
|
||||
To work around both of these issues, I have created a small program under
|
||||
configs/ea3152/tools to add the header. This program can be built under
|
||||
either Linux or Cygwin (and probably other tool environments as well). That
|
||||
tool can be built as follows:
|
||||
|
||||
- cd configs/ea3152/tools
|
||||
- make
|
||||
|
||||
Then, to build the NuttX binary ready to load with the bootloader, just
|
||||
following these steps:
|
||||
|
||||
- cd tools/ # Configure Nuttx
|
||||
- ./configure.sh ea3152/ostest # (using the ostest configuration for this example)
|
||||
- cd .. # Set up environment
|
||||
- . ./setenv.sh # (see notes below)
|
||||
- make # Make NuttX. This will produce nuttx.bin
|
||||
- mklpc.sh # Make the bootloader binary (nuttx.lpc)
|
||||
|
||||
NOTES:
|
||||
|
||||
1. setenv.sh just sets up pathes to the toolchain and also to
|
||||
configs/ea3152/tools where mklpc.sh resides. Use of setenv.sh is optional.
|
||||
If you don't use setenv.sh, then just set your PATH variable appropriately or
|
||||
use the full path to mklpc.sh in the final step.
|
||||
2. You can instruct Symantec to ignore the errors and it will stop quarantining
|
||||
the NXP program.
|
||||
3. The CRC32 logic in configs/ea3152/tools doesn't seem to work. As a result,
|
||||
the CRC is currently disabled in the header:
|
||||
|
||||
RCS file: /cvsroot/nuttx/nuttx/configs/ea3152/tools/lpchdr.c,v
|
||||
retrieving revision 1.2
|
||||
diff -r1.2 lpchdr.c
|
||||
264c264
|
||||
< g_hdr.imageType = 0x0000000b;
|
||||
---
|
||||
> g_hdr.imageType = 0x0000000a;
|
||||
|
||||
Image Download to ISRAM
|
||||
^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Assuming that you already have the FTDI driver installed*, then here is the
|
||||
are the steps that I use for loading new code into the EA3152:
|
||||
|
||||
- Create the bootloader binary, nuttx.lpc, as described above.
|
||||
- Connected the EA3152 using the FTDI USB port (not the lpc3152 USB port)
|
||||
This will power up the EA3152 and start the bootloader.
|
||||
- Start a terminal emulator (such as TeraTerm) at 115200 8NI.
|
||||
- Reset the EA3152 and you should see:
|
||||
LPC31xx READY FOR PLAIN IMAGE>
|
||||
- Send the nuttx.lpc file and you should see:
|
||||
Download finished
|
||||
|
||||
That will load the NuttX binary into ISRAM and attempt to execute it.
|
||||
|
||||
*See the LPC313x documentation if you do not have the FTDI driver installed.
|
||||
|
||||
Using OpenOCD and GDB
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
I have been using the Olimex ARM-USB-OCD JTAG debugger with the EA3152
|
||||
(http://www.olimex.com). The OpenOCD configuration file is here:
|
||||
tools/armusbocb.cfg. There is also a script on the tools directory that
|
||||
I used to start the OpenOCD daemon on my system called oocd.sh. That
|
||||
script would probably require some modifications to work in another
|
||||
environment:
|
||||
|
||||
- possibly the value of OPENOCD_PATH
|
||||
- If you are working under Linux you will need to change any
|
||||
occurances of `cygpath -w blablabla` to just blablabla
|
||||
|
||||
Then you should be able to start the OpenOCD daemon like:
|
||||
|
||||
configs/ea3152/tools/oocd.sh $PWD
|
||||
|
||||
Where it is assumed that you are executing oocd.sh from the top level
|
||||
directory where NuttX is installed.
|
||||
|
||||
Once the OpenOCD daemon has been started, you can connect to it via
|
||||
GDB using the following GDB command:
|
||||
|
||||
arm-elf-gdb
|
||||
(gdb) target remote localhost:3333
|
||||
|
||||
And you can load the NuttX ELF file:
|
||||
|
||||
(gdb) symbol-file nuttx
|
||||
(gdb) load nuttx
|
||||
|
||||
ARM/EA3152-specific Configuration Options
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
|
||||
be set to:
|
||||
|
||||
CONFIG_ARCH=arm
|
||||
|
||||
CONFIG_ARCH_family - For use in C code:
|
||||
|
||||
CONFIG_ARCH_ARM=y
|
||||
|
||||
CONFIG_ARCH_architecture - For use in C code:
|
||||
|
||||
CONFIG_ARCH_ARM926EJS=y
|
||||
|
||||
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
|
||||
|
||||
CONFIG_ARCH_CHIP=lpc313x
|
||||
|
||||
CONFIG_ARCH_CHIP_name - For use in C code
|
||||
|
||||
CONFIG_ARCH_CHIP_LPC3152
|
||||
|
||||
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
||||
hence, the board that supports the particular chip or SoC.
|
||||
|
||||
CONFIG_ARCH_BOARD=ea3152
|
||||
|
||||
CONFIG_ARCH_BOARD_name - For use in C code
|
||||
|
||||
CONFIG_ARCH_BOARD_EA3152
|
||||
|
||||
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 - For most ARM9 architectures, this describes the
|
||||
size of installed DRAM. For the LPC313X, it is used only to
|
||||
deterimine how to map the executable regions. It is SDRAM size
|
||||
only if you are executing out of the external SDRAM; or it could
|
||||
be NOR FLASH size, external SRAM size, or internal SRAM size.
|
||||
|
||||
CONFIG_DRAM_START - The start address of installed DRAM (physical)
|
||||
|
||||
CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
|
||||
|
||||
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
|
||||
have LEDs
|
||||
|
||||
CONFIG_ARCH_IRQPRIO - The LPC313x supports interrupt prioritization
|
||||
|
||||
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_BOOTLOADER - Set if you are using a bootloader.
|
||||
|
||||
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to board architecture.
|
||||
|
||||
CONFIG_ARCH_BUTTONS - Enable support for buttons. 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.
|
||||
CONFIG_ARCH_DMA - Support DMA initialization
|
||||
CONFIG_ARCH_LOWVECTORS - define if vectors reside at address 0x0000:00000
|
||||
Undefine if vectors reside at address 0xffff:0000
|
||||
CONFIG_ARCH_ROMPGTABLE - A pre-initialized, read-only page table is available.
|
||||
If defined, then board-specific logic must also define PGTABLE_BASE_PADDR,
|
||||
PGTABLE_BASE_VADDR, and all memory section mapping in a file named
|
||||
board_memorymap.h.
|
||||
|
||||

* be applied. Once the 100µs delay has been satisfied with at least one
|
||||
* COMMAND INHIBIT or NOP command having been applied, a PRECHARGE command
|
||||
* should be applied. All banks must then be precharged, thereby placing
|
||||
* the device in the all banks idle state.
|
||||
*
|
||||
* "Once in the idle state, two AUTO REFRESH cycles must be performed. After
|
||||
* the AUTO REFRESH cycles are complete, the SDRAM is ready for mode
|
||||
* register programming.
|
||||
*
|
||||
* "Because the mode register will power up in an unknown state, it should
|
||||
* be loaded prior to applying any operational command."
|
||||
*
|
||||
* The JEDEC recommendation for initializing SDRAM is:
|
||||
*
|
||||
* APPLY POWER (Vdd/Vddq equally, and CLK is stable)
|
||||
* Wait 200uS
|
||||
* PRECHARGE all
|
||||
* 8 AUTO REFRESH COMMANDS
|
||||
* LOAD MODE REGISTER
|
||||
* SDRAM is ready for operation
|
||||
*
|
||||
* The Micron SDRAM parts will work fine with the JEDEC sequence, but also
|
||||
* allow for a quicker init sequence of:
|
||||
*
|
||||
* APPLY POWER (Vdd/Vddq equally, and CLK is stable)
|
||||
* Wait at least 100uS (during which time start applying and
|
||||
* continue applying NOP or COMMAND INHIBIT)
|
||||
* PRECHARGE all
|
||||
* 2 AUTO REFRESH COMMANDS (min requirement, more than 2 is also ok)
|
||||
* LOAD MODE REGISTER
|
||||
* SDRAM is ready for operation

|
||||
*
|
||||
* 1. Provide logic in lpc31_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide lpc31_spiselect() and lpc31_spistatus() functions in your
|
||||
* board-specific logic. These functions will perform chip selection and
|
||||
* status operations using GPIOs in the way your board is configured.
|
||||
* 3. Add a calls 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).

*
|
||||
* The logic in this file was developed by Gary S. Brown:
|
||||
*
|

* COPYRIGHT (C) 1986 Gary S. Brown. You may use this program, or code or tables
|
||||
* extracted from it, as desired without restriction.
|
||||
*
|
||||
* First, the polynomial itself and its table of feedback terms. The polynomial is:
|
||||
*
|
||||
* X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
|
||||
*
|
||||
* Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
|
||||
* The X^32 term is "implied"; the LSB is the X^31 term, etc. The X^0 term (usually shown
|
||||
* as "+1") results in the MSB being 1
|
||||
*
|
||||
* Note that the usual hardware shift register implementation, which is what we're using
|
||||
* (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
|
||||
* lowest-order term. In our implementation, that means shifting towards the right. Why
|
||||
* do we do it this way? Because the calculated CRC must be transmitted in order from
|
||||
* highest-order term to lowest-order term. UARTs transmit characters in order from LSB
|
||||
* to MSB. By storing the CRC this way we hand it to the UART in the order low-byte to
|
||||
* high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
|
||||
* by bit from highest- to lowest-order term without requiring any bit shuffling on our
|
||||
* part. Reception works similarly
|
||||
*
|
||||
* The feedback terms table consists of 256, 32-bit entries. Notes
|
||||
*
|
||||
* - The table can be generated at runtime if desired; code to do so is shown later. It
|
||||
* might not be obvious, but the feedback terms simply represent the results of eight
|
||||
* shift/xor operations for all combinations of data and CRC register values
|
||||
*
|
||||
* - The values must be right-shifted by eight bits by the updcrc logic; the shift must
|
||||
* be u_(bring in zeroes). On some hardware you could probably optimize the shift in
|
||||
* assembler by using byte-swap instructions polynomial $edb88320
