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.
Individual subsystems can be enabled:
CONFIG_LPC31XX_MCI, CONFIG_LPC31XX_SPI, CONFIG_LPC31XX_UART
External memory available on the board (see also CONFIG_MM_REGIONS)
CONFIG_LPC31XX_EXTSRAM0 - Select if external SRAM0 is present
CONFIG_LPC31XX_EXTSRAM0HEAP - Select if external SRAM0 should be
configured as part of the NuttX heap.

external SDRAM memory
CONFIG_LPC31XX_EXTNAND - Select if external NAND is present
CONFIG_LPC31XX_EXTSDRAMSIZE - Size (in bytes) of the installed
external NAND memory
LPC313X specific device driver settings
CONFIG_UART_SERIAL_CONSOLE - selects the UART for the
console and ttys0
CONFIG_UART_RXBUFSIZE - Characters are buffered as received.
This specific the size of the receive buffer
CONFIG_UART_TXBUFSIZE - Characters are buffered before
being sent. This specific the size of the transmit buffer
CONFIG_UART_BAUD - The configure BAUD of the UART. Must be
CONFIG_UART_BITS - The number of bits. Must be either 7 or 8.
CONFIG_UART_PARTIY - 0=no parity, 1=odd parity, 2=even parity

# architecture selection
#
# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
# processor architecture.
# CONFIG_ARCH_family - for use in C code. This identifies the
# particular chip family that the architecture is implemented
# in.
# CONFIG_ARCH_architecture - for use in C code. This identifies the
# specific architecture within the chip familyl.
# CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
# CONFIG_ARCH_CHIP_name - For use in C code
# CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
# the board that supports the particular chip or SoC.
# CONFIG_ARCH_BOARD_name - for use in C code
# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
# CONFIG_BOARD_LOOPSPERMSEC - for delay loops
# CONFIG_DRAM_SIZE - For most ARM9 architectures, this describes the
# size of installed DRAM. For the LPC31XX, 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 DRAM (physical)
# CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
# CONFIG_ARCH_IRQPRIO - The LPC31xx 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 calibrate
# CONFIG_BOARD_LOOPSPERMSEC. You simply use a stop watch to measure
# the 100 second delay then adjust CONFIG_BOARD_LOOPSPERMSEC until
# the delay actually is 100 seconds.

# CONFIG_DEBUG - enables built-in debug options
# CONFIG_DEBUG_VERBOSE - enables verbose debug output
# CONFIG_DEBUG_SYMBOLS - build without optimization and with
# debug symbols (needed for use with a debugger).
# CONFIG_MM_REGIONS - If the architecture includes multiple
# regions of memory to allocate from, this specifies the
# number of memory regions that the memory manager must
# handle and enables the API mm_addregion(start, end);
# CONFIG_ARCH_LOWPUTC - architecture supports low-level, boot
# time console output
# CONFIG_MSEC_PER_TICK - The default system timer is 100Hz
# or MSEC_PER_TICK=10. This setting may be defined to
# inform NuttX that the processor hardware is providing
# system timer interrupts at some interrupt interval other
# than 10 msec.
# CONFIG_RR_INTERVAL - The round robin timeslice will be set
# this number of milliseconds; Round robin scheduling can
# be disabled by setting this value to zero.
# CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in
# scheduler to monitor system performance
# CONFIG_TASK_NAME_SIZE - Spcifies that maximum size of a
# task name to save in the TCB. Useful if scheduler
# instrumentation is selected. Set to zero to disable.
# CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY -
# Used to initialize the internal time logic.
# CONFIG_GREGORIAN_TIME - Enables Gregorian time conversions.
# You would only need this if you are concerned about accurate
# time conversions in the past or in the distant future.
# CONFIG_JULIAN_TIME - Enables Julian time conversions. You
# would only need this if you are concerned about accurate
# time conversion in the distand past. You must also define
# CONFIG_GREGORIAN_TIME in order to use Julian time.
# CONFIG_DEV_CONSOLE - Set if architecture-specific logic
# provides /dev/console. Enables stdout, stderr, stdin.
# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
# driver (minimul support)
# CONFIG_MUTEX_TYPES: Set to enable support for recursive and
# errorcheck mutexes. Enables pthread_mutexattr_settype().
# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
# inheritance on mutexes and semaphores.
# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
# inheritance is enabled. It defines the maximum number of
# different threads (minus one) that can take counts on a
# semaphore with priority inheritance support. This may be
# set to zero if priority inheritance is disabled OR if you
# are only using semaphores as mutexes (only one holder) OR
# if no more than two threads participate using a counting
# semaphore.
# CONFIG_SEM_NNESTPRIO. If priority inheritance is enabled,
# then this setting is the maximum number of higher priority
# threads (minus 1) than can be waiting for another thread
# to release a count on a semaphore. This value may be set
# to zero if no more than one thread is expected to wait for
# a semaphore.
# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
# by task_create() when a new task is started. If set, all
# files/drivers will appear to be closed in the new task.
# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
# three file descriptors (stdin, stdout, stderr) by task_create()
# when a new task is started. If set, all files/drivers will
# appear to be closed in the new task except for stdin, stdout,
# and stderr.
# CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
# desciptors by task_create() when a new task is started. If
# set, all sockets will appear to be closed in the new task.
# CONFIG_NXFLAT. Enable support for the NXFLAT binary format.
# This format will support execution of NuttX binaries located
# in a ROMFS filesystem (see examples/nxflat).
# CONFIG_SCHED_WORKQUEUE. Create a dedicated "worker" thread to
# handle delayed processing from interrupt handlers. This feature
# is required for some drivers but, if there are not complaints,
# can be safely disabled. The worker thread also performs
# garbage collection -- completing any delayed memory deallocations
# from interrupt handlers. If the worker thread is disabled,
# then that clean will be performed by the IDLE thread instead
# (which runs at the lowest of priority and may not be appropriate
# if memory reclamation is of high priority). If CONFIG_SCHED_WORKQUEUE
# is enabled, then the following options can also be used:
# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
# thread. Default: 50
# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
# work in units of microseconds. Default: 50*1000 (50 MS).
# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
# thread. Default: CONFIG_IDLETHREAD_STACKSIZE.
# CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
# the worker thread. Default: 4

/****************************************************************************
* Name: up_fillpage()
*
* Description:
* After a page is allocated and mapped by up_allocpage(), the actual
* filling of the page with data from the non-volatile, must be performed
* by a separate call to the architecture-specific function, up_fillpage().
* This function is non-blocking, it will start an asynchronous page fill.
* The common paging logic will provide a callback function, pg_callback,
* that will be called when the page fill is finished (or an error occurs).
* This callback is assumed to occur from an interrupt level when the
* device driver completes the fill operation.
*
* NOTE 1: Allocating and filling a page is a two step process. up_allocpage()
* allocates the page, and up_fillpage() fills it with data from some non-
* volatile storage device. This distinction is made because up_allocpage()
* can probably be implemented in board-independent logic whereas up_fillpage()
* probably must be implemented as board-specific logic.
*
* NOTE 2: The initial mapping of vpage will be read-able, write-able,
* but non-cacheable. No special actions will be required of
* up_fillpage() in order to write into this allocated page. If the
* virtual address maps to a text region, however, this function should
* remap the region so that is is read/execute only. It should be made
* cache-able in any case.
* Input Parameters:
* tcb - A reference to the task control block of the task that needs to
* have a page fill. Architecture-specific logic can retrieve page
* fault information from the architecture-specific context
* information in this TCB to perform the fill.
* pg_callbck - The function to be called when the page fill is complete.
*
* Returned Value:
* This function will return zero (OK) if the page fill was successfully
* started (the result of the page fill is passed to the callback function
* as the result argument). A negated errno value may be returned if an
* error occurs. All errors, however, are fatal.
*
* NOTE: -EBUSY has a special meaning. It is used internally to mean that
* the callback function has not executed. Therefore, -EBUSY should
* never be provided in the result argument of pg_callback.
*
* Assumptions:
* - This function is called from the normal tasking context (but
* interrupts siabled). The implementation must take whatever actions
* are necessary to assure that the operation is safe within this context.
* - Upon return, the caller will sleep waiting for the page fill callback
* to occur. The callback function will perform the wakeup.

* Description:
* Configure SDRAM on the EA3152 board
*
* Micron Initialization Sequence from their data sheet for the Micron
* MT48LC32M16A2 32M x 16 SDRAM chip:
*
* "SDRAMs must be powered up and initialized in a predefined manner.
* Operational procedures other than those specified may result in
* undefined operation. Once power is applied to VDD and VDDQ
* (simultaneously) and the clock is stable (stable clock is defined as
* a signal cycling within timing constraints specified for the clock
* pin), the SDRAM requires a 100µs delay prior to issuing any command
* other than a COMMAND INHIBIT or NOP.
*
* "Starting at some point during this 100µs period and continuing at least
* through the end of this period, COMMAND INHIBIT or NOP commands should
* 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:

/************************************************************************************************
* configs/ea3152/tools/crc32.c
*
* This file is a part of NuttX:
*
* Copyright (C) 2011 Gregory Nutt. All rights reserved.
*
* 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
