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. Testing was performed using the Cygwin
|
|
environment.
|
|
|
|
GNU Toolchain Options
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The NuttX make system has been modified to support the following different
|
|
toolchain options.
|
|
|
|
1. The Code Red GNU toolchain
|
|
2. The CodeSourcery GNU toolchain,
|
|
3. The devkitARM GNU toolchain,
|
|
4. The NuttX buildroot Toolchain (see below).
|
|
|
|
All testing has been conducted using the Code Red toolchain and the
|
|
make system is setup to default to use the Code Red Linux toolchain. To use
|
|
the other toolchain, you simply need add one of the following configuration
|
|
options to your .config (or defconfig) file:
|
|
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
|
|
CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y : devkitARM under Windows
|
|
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODEREDW=y : Code Red toolchain under Windows
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODEREDL=y : Code Red toolchain under Linux
|
|
CONFIG_ARMV7M_TOOLCHAIN_ATOLLIC=y : The Atollic toolchain
|
|
|
|
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 Code Red (for Windoes)
|
|
are Windows native toolchains. The CodeSourcey (for Linux), Code Red (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.
|
|
|
|
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.
|
|
|
|
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
|
|
Bitbucket download site (https://bitbucket.org/nuttx/nuttx/downloads/).
|
|
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 zkit-arm-1769/<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/cortexm3-defconfig-4.3.3 .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.
|
|
|
|
NOTE: The cortexm3-defconfig-4.3.3 produces an older-style is OABI toolchain.
|
|
There is another configuration, cortexm3-eabi-defconfig-4.6.3, that will
|
|
build a newer, EABI, toolchain. Unfortunately, the 4.6.3 EABI toolchain is
|
|
not compatible with the NXFLAT tools. See the top-level TODO file (under
|
|
"Binary loaders") for more information about this problem. If you plan to
|
|
use NXFLAT, please do not use the GCC 4.6.3 EABI toochain; instead use the
|
|
GCC 4.3.3 OABI toolchain.
|
|
|
|
NXFLAT Toolchain
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
If you are *not* using the NuttX buildroot toolchain and you want to use
|
|
the NXFLAT tools, then you will still have to build a portion of the buildroot
|
|
tools -- just the NXFLAT tools. The buildroot with the NXFLAT tools can
|
|
be downloaded from the NuttX Bitbucket download site
|
|
(https://bitbucket.org/nuttx/nuttx/downloads/).
|
|
|
|
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 zkit-arm-1769/<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/cortexm3-defconfig-nxflat .config
|
|
|
|
6. make oldconfig
|
|
|
|
7. make
|
|
|
|
8. Edit setenv.h, if necessary, so that the PATH variable includes
|
|
the path to the newly builtNXFLAT binaries.
|
|
|
|
LEDs
|
|
^^^^
|
|
|
|
If CONFIG_ARCH_LEDS is defined, then support for the ZKit-ARM LEDs will be
|
|
included in the build. See:
|
|
|
|
- configs/zkit-arm-1769/include/board.h - Defines LED constants, types and
|
|
prototypes the LED interface functions.
|
|
|
|
- configs/zkit-arm-1769/src/zkit-arm-1769.h - GPIO settings for the LEDs.
|
|
|
|
- configs/zkit-arm-1769/src/up_leds.c - LED control logic.
|
|
|
|
The ZKit-ARM LPC1768 has a single LEDs (there are more on the Embedded Artists
|
|
base board, but those are not controlled by NuttX). Usage this single LED by NuttX
|
|
is as follows:
|
|
|
|
- The LED is not illuminated until the ZKit-ARM completes initialization.
|
|
|
|
If the LED is stuck in the OFF state, this means that the ZKit-ARM did not
|
|
complete initializeation.
|
|
|
|
- Each time the OS enters an interrupt (or a signal) it will turn the LED OFF and
|
|
restores its previous stated upon return from the interrupt (or signal).
|
|
|
|
The normal state, after initialization will be a dull glow. The brightness of
|
|
the glow will be inversely related to the proportion of time spent within interrupt
|
|
handling logic. The glow may decrease in brightness when the system is very
|
|
busy handling device interrupts and increase in brightness as the system becomes
|
|
idle.
|
|
|
|
Stuck in the OFF state suggests that that the system never completed
|
|
initialization; Stuck in the ON state would indicated that the system
|
|
intialialized, but is not takint interrupts.
|
|
|
|
- If a fatal assertion or a fatal unhandled exception occurs, the LED will flash
|
|
strongly as a slow, 2Hz rate.
|
|
|
|
ZKit-ARM Configuration Options
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
General Architecture Settings:
|
|
|
|
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_CORTEXM3=y
|
|
|
|
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
|
|
|
|
CONFIG_ARCH_CHIP=lpc17xx
|
|
|
|
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
|
|
chip:
|
|
|
|
CONFIG_ARCH_CHIP_LPC1768=y
|
|
|
|
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
|
hence, the board that supports the particular chip or SoC.
|
|
|
|
CONFIG_ARCH_BOARD=zkit-arm-1769
|
|
|
|
CONFIG_ARCH_BOARD_name - For use in C code
|
|
|
|
CONFIG_ARCH_BOARD_ZKITARM=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_RAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
|
|
|
|
CONFIG_RAM_SIZE=(32*1024) (32Kb)
|
|
|
|
There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
|
|
|
|
CONFIG_RAM_START - The start address of installed DRAM
|
|
|
|
CONFIG_RAM_START=0x10000000
|
|
|
|
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.

Probably a bad idea... Unless there is some issue with sampling the SOF
|
|
from hardware asynchronously.
|
|
CONFIG_LPC17_USBDEV_EPFAST_INTERRUPT
|
|
Enable high priority interrupts. I have no idea why you might want to
|
|
do that

|
|
Number of DMA descriptors to allocate in SRAM.
|
|
CONFIG_LPC17_USBDEV_DMA
|
|

|
|
Define if the hardware implementation does not support the VBUS signal
|
|
CONFIG_LPC17_USBDEV_NOLED
|
|
Define if the hardware implementation does not support the LED output
|
|
|
|
LPC17xx USB Host Configuration (the ZKit-ARM does not support USB Host)
|
|
|
|
CONFIG_USBHOST_OHCIRAM_SIZE
|
|
Total size of OHCI RAM (in AHB SRAM Bank 1)
|
|
CONFIG_USBHOST_NEDS
|
|
Number of endpoint descriptors
|
|
CONFIG_USBHOST_NTDS
|
|
Number of transfer descriptors
|
|
CONFIG_USBHOST_TDBUFFERS
|
|
Number of transfer descriptor buffers
|
|
CONFIG_USBHOST_TDBUFSIZE
|
|
Size of one transfer descriptor buffer
|
|
CONFIG_USBHOST_IOBUFSIZE
|
|
Size of one end-user I/O buffer. This can be zero if the
|
|
application can guarantee that all end-user I/O buffers
|
|
reside in AHB SRAM.
|

Configurations
|
|
^^^^^^^^^^^^^^
|
|
|
|
Each ZKit-ARM configuration is maintained in a sudirectory and can be
|
|
selected as follow:
|
|
|
|
cd tools
|
|
./configure.sh zkit-arm-1769/<subdir>
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
hello:
|
|
This builds an example application using apps/examples/hello. See
|
|
apps/examples/README.txt for information about the examples.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configuration using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. Default toolchain:
|
|
|
|
CONFIG_HOST_LINUX=y : Builds under Windows (or Cygwin)
|
|
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot toolchain
|
|
|
|
thttpd:
|
|
This builds the THTTPD web server example using the THTTPD and
|
|
the apps/examples/thttpd application.
|
|

CONFIG_EXAMPLES_THTTPD_NOMAC=y : Will use MAC 00:e0:de:ad:be:ef
|
|
CONFIG_EXAMPLES_THTTPD_DRIPADDR=0xac100002 : Gateway 172.16.00.02
|
|
CONFIG_EXAMPLES_THTTPD_NETMASK=0xffffff00 : Netmask 255.255.255.0
|
|
|
|
4. You will need to build the NXFLAT toolchain as described above in
|
|
order to use this example.
