See include/nuttx/can.h for further CAN driver information.
if CAN
config CAN_EXTID

config CAN_LOOPBACK
bool "CAN extended IDs"
default n
---help---
A CAN driver may or may not support a loopback mode for testing. If the
driver does support loopback mode, the setting will enable it. (If the
driver does not, this setting will have no effect).
endif
menuconfig PWM
bool "PWM Driver Support"
default n
---help---
This selection enables building of the "upper-half" PWM driver.
See include/nuttx/pwm.h for further PWM driver information.
if PWM

---help---
Some hardware will support generation of a fixed number of pulses. This
might be used, for example to support a stepper motor. If the hardware
will support a fixed pulse count, then this configuration should be set to
enable the capability.
endif
menuconfig I2C
bool "I2C Driver Support"
default n

configuration will be performed. It is not necessary for clients to lock,
re-configure, etc..

default y
---help---
Driver supports a single exchange method (vs a recvblock() and sndblock ()methods).
config SPI_CMDDATA
bool "SPI CMD/DATA"
default n
---help---
Devices on the SPI bus require out-of-band support to distinguish command
transfers from data transfers. Such devices will often support either 9-bit
SPI (yech) or 8-bit SPI and a GPIO output that selects between command and data.
endif
menuconfig RTC
bool "RTC Driver Support"
default n
---help---
This selection enables configuration of a real time clock (RTCdriver.
See include/nuttx/rtc.h for further watchdog timer driver information.
Most RTC drivers are MCU specific and may require other specific settings.
config RTC_DATETIME
bool "Date/Time RTC Support"
default n
depends on RTC
---help---
There are two general types of RTC: (1) A simple battery backed counter
that keeps the time when power is down, and (2) a full date / time RTC the
provides the date and time information, often in BCD format. If
RTC_DATETIME is selected, it specifies this second kind of RTC. In this
case, the RTC is used to "seed" the normal NuttX timer and the NuttX system
timer provides for higher resolution time.
config RTC_HIRES
bool "Hi-Res RTC Support"
default n
depends on RTC && !RTC_DATETIME
---help---
If RTC_DATETIME not selected, then the simple, battery backed counter is
used. There are two different implementations of such simple counters
based on the time resolution of the counter: The typical RTC keeps time
to resolution of 1 second, usually supporting a 32-bit time_t value. In
this case, the RTC is used to "seed" the normal NuttX timer and the NuttX
timer provides for higherresoution time.
If RTC_HIRES is enabled in the NuttX configuration, then the RTC provides
higher resolution time and completely replaces the system timer for purpose
of date and time.
config RTC_FREQUENCY
int "Hi-Res RTC frequency"
default 1
depends on RTC && !RTC_DATETIME && RTC_HIRES
---help---
If RTC_HIRES is defined, then the frequency of the high resolution RTC
must be provided. If RTC_HIRES is not defined, RTC_FREQUENCY is assumed
to be one Hz.
config RTC_ALARM
bool "RTC Alarm Support"
default n
depends on RTC
---help---
Enable if the RTC hardware supports setting of an alarm. A callback
function will be executed when the alarm goes off.
menuconfig WATCHDOG
bool "Watchdog Timer Support"
default n
---help---
This selection enables building of the "upper-half" watchdog timer driver.
See include/nuttx/watchdog.h for further watchdog timer driver information.

menuconfig BCH
bool "Block-to-Character (BCH) Support"

information.

default n
---help---
Memory Technology Device (MTD) drivers. Some simple drivers for
memory technologies like FLASH, EEPROM, NVRAM, etc. See
include/nuttx/mtd.h
(Note: This is a simple memory interface and should not be
confused with the "real" MTD developed at infradead.org. This
logic is unrelated; I just used the name MTD because I am not
aware of any other common way to refer to this class of devices).
if MTD

See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed the usage
of nuttx with sercomm.
drivers/sercomm is only built if SERCOMM_CONSOLE in the NuttX

osmocom-bb, you will get compilation errors because of header files
that are needed from the osmocom-bb.
