With most MCUs, NuttX is built as a flat, single executable image

The RTOS code and the application run in the same address space and at the same kernel-mode privileges.
If this option is selected, NuttX will be built separately as a monolithic, kernel-mode module and the applications

In this a system call layer will be built to support the user- to kernel-mode interface to the RTOS.

#
# CONFIG_APPS_DIR - Identifies the relative path to the directory
# that builds the application to link with NuttX. Default: ../apps
# 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_NUTTX_KERNEL - Builds NuttX as a separately compiled kernel.
# 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_TICKS_PER_MSEC - The default system timer is 100Hz
# or TICKS_PER_MSEC=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

# CONFIG_NX_MULTIUSER
# Configures NX in multi-user mode
# CONFIG_NX_NPLANES
# Some YUV color formats requires support for multiple planes,
# one for each color component. Unless you have such special
# hardware, this value should be undefined or set to 1
# CONFIG_NX_DISABLE_1BPP, CONFIG_NX_DISABLE_2BPP,
# CONFIG_NX_DISABLE_4BPP, CONFIG_NX_DISABLE_8BPP,

# NX supports a variety of pixel depths. You can save some
# memory by disabling support for unused color depths.
# CONFIG_NX_PACKEDMSFIRST
# If a pixel depth of less than 8-bits is used, then NX needs
# to know if the pixels pack from the MS to LS or from LS to MS
# CONFIG_NX_LCDDRIVER
# By default, NX builds to use a framebuffer driver (see
# include/nuttx/fb.h). If this option is defined, NX will
# build to use an LCD driver (see include/nuttx/lcd/lcd.h).
# CONFIG_LCD_MAXPOWER - The full-on power setting for an LCD device.
# CONFIG_LCD_MAXCONTRAST - The maximum contrast value for an LCD device.
# CONFIG_NX_MOUSE
# Build in support for mouse input
# CONFIG_NX_KBD
# Build in support of keypad/keyboard input
# CONFIG_NXTK_BORDERWIDTH
# Specifies with with of the border (in pixels) used with
# framed windows. The default is 4.
# CONFIG_NXTK_BORDERCOLOR1 and CONFIG_NXTK_BORDERCOLOR2
# Specify the colors of the border used with framed windows.
# CONFIG_NXTK_BORDERCOLOR2 is the shadow side color and so
# is normally darker. The default is medium and dark grey,
# respectively
# CONFIG_NXTK_AUTORAISE
# If set, a window will be raised to the top if the mouse position
# is over a visible portion of the window. Default: A mouse
# button must be clicked over a visible portion of the window.
# CONFIG_NXFONTS_CHARBITS
# The number of bits in the character set. Current options are
# only 7 and 8. The default is 7.
# CONFIG_NXFONT_SANS
# At present, there is only one font. But if there were were more,
# then this option would select the sans serif font.
#
# NX Multi-user only options:
#
# CONFIG_NX_BLOCKING
# Open the client message queues in blocking mode. In this case,
# nx_eventhandler() will not return until a message is received and processed.
# CONFIG_NX_MXSERVERMSGS and CONFIG_NX_MXCLIENTMSGS
# Specifies the maximum number of messages that can fit in
# the message queues. No additional resources are allocated, but
# this can be set to prevent flooding of the client or server with
# too many messages (CONFIG_PREALLOC_MQ_MSGS controls how many
# messages are pre-allocated).
