Default: ../apps This symbol must be assigned to the path to the application build directory *relative* to the NuttX top build direcory. If you had an application directory and the NuttX directory each in separate directory trees like this: build |-nuttx | | | `- Makefile `-application | `- Makefile Then you would set CONFIG_APPS_DIR=../application. The application direction must contain Makefile and this make file must support the following targets: libapps$(LIBEXT) (usually libapps.a). libapps.a is a static library ( an archive) that contains all of application object files. clean. Do whatever is appropriate to clean the application directories for a fresh build. distclean. Clean everthing -- auto-generated files, symbolic links etc. -- so that the directory contents are the same as the contents in your configuration management system. This is only done when you change the NuttX configuration. depend. Make or update the application build dependencies. When this application is invoked it will receive the setting TOPDIR like: $(MAKE) -C $(CONFIG_APPS_DIR) TOPDIR="$(TOPDIR)" TOPDIR is the full path to the NuttX directory. It can be used, for example, to include makefile fragments (e.g., .config or Make.defs) or to set up include file paths. config BUILD_2PASS bool "Two pass build" default n ---help--- Enables the two pass build options. Two-pass build options. If the 2 pass build option is selected, then these options configure the make system build a extra link object. This link object is assumed to be an incremental (relative) link object, but could be a static library (archive) (some modification to this Makefile would be required if CONFIG_PASS1_TARGET generates an archive). Pass 1 1ncremental (relative) link objects should be put into the processor-specific source directory (where other link objects will be created). If the pass1 obect is an archive, it could go anywhere. if BUILD_2PASS config PASS1_TARGET string "Pass one target" default "" ---help--- The name of the first pass build target. This can be specific build target, a special build target (all, default, etc.) or may just be left undefined. config PASS1_BUILDIR string "Pass one build directory" default "build" ---help--- The path, relative to the top NuttX build directory to directory that contains the Makefile to build the first pass object. The Makefile must support the following targets: The special target CONFIG_PASS1_TARGET (if defined) and the usual depend, clean, and distclean targets. config PASS1_OBJECT string "Pass one object" default "" ---help--- May be used to include an extra, pass1 object into the final link. This would probably be the object generated from the CONFIG_PASS1_TARGET. It may be available at link time in the arch//src directory. config NUTTX_KERNEL bool "NuttX kernel build" default n ---help--- Builds NuttX as a separately compiled kernel. endif endmenu menu "Binary Output Formats" config RRLOAD_BINARY bool "rrload binary format" default n ---help--- Create nuttx.rr in the rrload binary format used with BSPs from www.ridgerun.com using the tools/mkimage.sh script. config INTELHEX_BINARY bool "Intel HEX binary format" default n ---help--- Create the nuttx.hex in the Intel HEX binary format that is used with many different loaders. This option will use the GNU objcopy program and should not be selected if you are not using the GNU toolchain. config MOTOROLA_SREC bool "Motorola S-Record binary format" default n ---help--- Create the nuttx.srec in the Motorola S-Record binary format that is used with many different loaders. This option will use the GNU objcopy program and should not be selected if you are not using the GNU toolchain. config RAW_BINARY bool "Raw binary format" default n ---help--- Create the nuttx.bin in the raw binary format that is used with many different loaders using the GNU objcopy program. This option should not be selected if you are not using the GNU toolchain. endmenu menu "Customize Header Files" config ARCH_STDBOOL_H bool "stdbool.h" default n ---help--- The stdbool.h header file can be found at nuttx/include/stdbool.h. However, that header includes logic to redirect the inclusion of an architecture specific header file like: #ifdef CONFIG_ARCH_STDBOOL_H # include #else ... #endif Recall that that include path, include/arch, is a symbolic link and will refer to a version of stdbool.h at nuttx/arch//include/stdbool.h. config ARCH_MATH_H bool "math.h" default n ---help--- There is also a re-directing version of math.h in the source tree. However, it resides out-of-the-way at include/nuttx/math.h because it conflicts too often with the system math.h. If ARCH_MATH_H=y is defined, however, the top-level makefile will copy the redirecting math.h header file from include/nuttx/math.h to include/math.h. math.h will then include the architecture-specific version of math.h that you must provide at nuttx/arch/>architecture #endif So for the architectures that define ARCH_MATH_H=y, include/math.h will be the redirecting math.h header file; for the architectures that don't select ARCH_MATH_H, the redirecting math.h header file will stay out-of-the-way in include/nuttx/. config ARCH_STDARG_H bool "stdarg.h" default n ---help--- There is also a redirecting version of stdarg.h in the source tree as well. It also resides out-of-the-way at include/nuttx/stdarg.h. This is because you should normally use your toolchain's stdarg.h file. But sometimes, your toolchain's stdarg.h file may have other header file dependencies and so may not be usable in the NuttX build environment. In those cases, you may have to create a architecture- specific stdarg.h header file at nuttx/arch//include/stdarg.h If ARCH_STDARG_H=y is defined, the top-level makefile will copy the re-directing stdarg.h header file from include/nuttx/stdarg.h to include/stdarg.h. So for the architectures that cannot use their toolchain's stdarg.h file, they can use this alternative by defining ARCH_STDARG_H=y and providing. If ARCH_STDARG_H, is not defined, then the stdarg.h header file will stay out-of-the-way in include/nuttx/. endmenu menu "Debug Options" config DEBUG bool "Enable debug features" default n ---help--- Enables built-in debug features. Selecting this option will (1) Enable debug assertions in the code, (2) enable extended parameter testing in many functions, and (3) enable support for debug output. Note that enabling this option by itself does not produce debug output. Debug output must also be selected on a subsystem-by-subsystem basis. if DEBUG config DEBUG_VERBOSE bool "Enable debug verbose output" default n ---help--- Enables verbose debug output (assuming debug output is enabled) config DEBUG_ENABLE bool "Enable debug controls" default n ---help--- Support an interface to dynamically enable or disable debug output. config DEBUG_SCHED bool "Enable scheduler debug output" default n ---help--- Enable OS debug output (disabled by default) config DEBUG_MM bool "Enable memory manager debug output" default n ---help--- Enable memory management debug output (disabled by default) config DEBUG_NET bool "Enable network debug output" default n ---help--- Enable network debug output (disabled by default) config DEBUG_USB bool "Enable USB debug output" default n ---help--- Enable usb debug output (disabled by default) config DEBUG_FS bool "Enable file system debug output" default n ---help--- Enable file system debug output (disabled by default) config DEBUG_LIB bool "Enable C library debug output" default n ---help--- Enable C library debug output (disabled by default) config DEBUG_BINFMT bool "Enable binary loader debug output" default n ---help--- Enable binary loader debug output (disabled by default) config DEBUG_GRAPHICS bool "Enable graphics debug output" default n ---help--- Enable NX graphics debug output (disabled by default) config DEBUG_I2C bool "Enable I2C debug output" default n ---help--- Enable I2C driver debug output (disabled by default) config DEBUG_SPI bool "Enable SPI debug output" default n ---help--- Enable I2C driver debug output (disabled by default) config DEBUG_WATCHDOG bool "Enable watchdog timer debug output" default n ---help--- Enable watchdog timer debug output (disabled by default) endif config DEBUG_SYMBOLS bool "Enable debug symbols" default n ---help--- Build without optimization and with debug symbols (needed for use with a debugger). endmenu endmenu menu "System Type" source "arch/Kconfig" endmenu menu "Board Selection" source "configs/Kconfig" endmenu menu "RTOS Features" source sched/Kconfig endmenu menu "Device Drivers" source drivers/Kconfig endmenu menu "Networking Support" source net/Kconfig endmenu menu "File Systems" source fs/Kconfig endmenu menu "Graphics Support" source graphics/Kconfig endmenu menu "Memory Management" source mm/Kconfig endmenu menu "Library Routines" source lib/Kconfig source libxx/Kconfig endmenu menu "Application Configuration" source "$APPSDIR/Kconfig" endmenu
