config LOOP
|
|
bool "Enable loop device"
|
|
default n
|
|
---help---
|
|
Supports the standard loop device that can be used to export a
|
|
file (or character device) as a block device. See losetup() and
|
|
loteardown() in include/nuttx/fs/fs.h.
|
|
|
|
config RAMDISK
|
|
bool "RAM disk support"
|
|
default n
|
|
---help---
|
|
Can be used to set up a block of memory or (read-only) FLASH as
|
|
a block driver that can be mounted as a files system. See
|
|
include/nuttx/ramdisk.h.
|
|
|
|
config RAMLOG
|
|
bool "RAM log message support"
|
|
default n
|
|
---help---
|
|
This is a driver that was intended to support debugging output,
|
|
aka syslogging, when the normal serial output is not available.
|
|
For example, if you are using a telnet or USB serial console,
|
|
the debug output will get lost.
|
|
|
|
This driver is similar to a pipe in that it saves the debugging
|
|
output in a FIFO in RAM. It differs from a pipe in numerous
|
|
details as needed to support logging.
|
|
|
|
if RAMLOG
|
|
config RAMLOG_SYSLOG
|
|
bool "Use RAMLOG for SYSLOG"
|
|
default n
|
|
depends on SYSLOG
|
|
---help---
|
|
Use the RAM logging device for the syslogging interface. If this feature
|
|
is enabled (along with SYSLOG), then all debug output (only) will be re-directed
|
|
to the circular buffer in RAM. This RAM log can be view from NSH using the
|
|
'dmesg'command.
|
|
|
|
config RAMLOG_CONSOLE
|
|
bool "Use RAMLOG for /dev/console"
|
|
default n
|
|
depends on DEV_CONSOLE
|
|
---help---
|
|
Use the RAM logging device as a system console. If this feature is enabled (along
|
|
with DEV_CONSOLE), then all console output will be re-directed to a circular
|
|
buffer in RAM. This is useful, for example, if the only console is a Telnet
|
|
console. Then in that case, console output from non-Telnet threads will go to
|
|
the circular buffer and can be viewed using the NSH 'dmesg' command.
|
|
|
|

int "RAMLOG buffer size"
|
|
default 1024

|
|
config RAMLOG_CRLF
|
|
bool "RAMLOG CR/LF"
|
|
default n
|
|
---help---
|
|
Pre-pend a carriage return before every linefeed that goes into the RAM log.
|
|
|
|
config RAMLOG_NONBLOCKING
|
|
bool "RAMLOG non-block reads"
|
|
default y
|
|
---help---
|
|
Reading from the RAMLOG will never block if the RAMLOG is empty. If the RAMLOG
|
|
is empty, then zero is returned (usually interpreted as end-of-file).
|
|
|
|
config RAMLOG_NPOLLWAITERS
|
|
int "RAMLOG number of poll waiters"
|
|
default 4
|
|
depends on !DISABLE_POLL

The size of the list of pending RTR requests. Default: 4
|

|
|
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).

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.

config SPI_CMDDATA

bool "SPI CMD/DATA"
|
|
default y
|

---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.
