Default is 512/1024. config NSH_STRERROR bool "Use strerror()" default n depends on LIBC_STRERROR ---help--- strerror(errno) makes more readable output but strerror() is very large and will not be used unless this setting is 'y' This setting depends upon the strerror() having been enabled with LIBC_STRERROR. config NSH_LINELEN int "Max command line length" default 64 if DEFAULT_SMALL default 80 if !DEFAULT_SMALL ---help--- The maximum length of one command line and of one output line. Default: 64/80 config NSH_DISABLE_SEMICOLON bool "Disable multiple commands per line" default y if DEFAULT_SMALL default n if !DEFAULT_SMALL ---help--- By default, you can enter multiple NSH commands on a line with each command separated by a semicolon. You can disable this feature to save a little memory on FLASH challenged platforms. config NSH_CMDPARMS bool "Enable commands as parameters" default n if DEFAULT_SMALL default y if !DEFAULT_SMALL depends on !DISABLE_MOUNTPOINT ---help--- If selected, then the output from commands, from file applications, and from NSH built-in commands can be used as arguments to other commands. The entity to be executed is identified by enclosing the command line in back quotes. For example, set FOO `myprogram $BAR` Will execute the program named myprogram passing it the value of the environment variable BAR. The value of the environment variable FOO is then set output of myprogram on stdout. Because this feature commits significant resources, it is disabled by default. config NSH_TMPDIR string "Temporary file directory" default "/tmp" depends on NSH_CMDPARMS ---help--- If NSH_CMDPARMS is selected, then function output will be retained in a temporary file. In that case, this string must be provided to specify the full path to a directory where temporary files can be created. This would be a good application of RAM disk: To provide temporary storage for function output. config NSH_MAXARGUMENTS int "Maximum number of command arguments" default 6 ---help--- The maximum number of NSH command arguments. Default: 6 config NSH_ARGCAT bool "Concatenation of argument strings" default n if DEFAULT_SMALL default y if !DEFAULT_SMALL ---help--- Support concatenation of strings with environment variables or command output. For example: set FOO XYZ set BAR 123 set FOOBAR ABC_${FOO}_${BAR} would set the environment variable FOO to XYZ, BAR to 123 and FOOBAR to ABC_XYZ_123. If NSH_ARGCAT is not selected, then a slightly small FLASH footprint results but then also only simple environment variables like $FOO can be used on the command line. config NSH_NESTDEPTH int "Maximum command nesting" default 3 ---help--- The maximum number of nested if-then[-else]-fi sequences that are permissable. Default: 3 config NSH_DISABLESCRIPT bool "Disable script support" default y if DEFAULT_SMALL default n if !DEFAULT_SMALL ---help--- This can be set to 'y' to suppress support for scripting. This setting disables the 'sh', 'test', and '[' commands and the if-then[-else]-fi construct.

This would only be set on systems where some minimal scripting is required but looping is not. endif # !NSH_DISABLESCRIPT config NSH_DISABLEBG bool "Disable background commands" default y if DEFAULT_SMALL default n if !DEFAULT_SMALL ---help--- This can be set to 'y' to suppress support for background commands. This setting disables the 'nice' command prefix and the '&' command suffix. This would only be set on systems where a minimal footprint is a necessity and background command execution is not. config NSH_MMCSDMINOR int "MMC/SD minor device number" default 0 ---help--- If the architecture supports an MMC/SD slot and if the NSH architecture specific logic is present, this option will provide the MMC/SD minor number, i.e., the MMC/SD block driver will be registered as /dev/mmcsdN where N is the minor number. Default is zero. config NSH_ROMFSETC bool "Support ROMFS start-up script" default n depends on FS_ROMFS ---help--- Mount a ROMFS filesystem at /etc and provide a startup script at /etc/init.d/rcS. The default startup script will mount a FAT FS RAMDISK at /tmp but the logic is easily extensible. endif # NSH_LIBRARY if NSH_ROMFSETC config NSH_ROMFSRC bool "Support ROMFS login script" default n ---help--- The ROMFS start-up script will be executed excactly once. For simple, persistence consoles (like a serial console). But with other other kinds of consoles, there may be multiple, transient sessions (such as Telnet and USB consoles). In these cases, you may need another script that is executed at the beginning of each session. Selecting this option enables support for such a login script config NSH_ROMFSMOUNTPT string "ROMFS mount point" default "/etc" ---help--- The default mountpoint for the ROMFS volume is /etc, but that can be changed with this setting.

The default is '0' corresponding to /dev/ram0. config NSH_ROMFSSECTSIZE int "ROMFS sector size" default 64 ---help--- This is the sector size to use with the ROMFS volume. Since the default volume is very small, this defaults to 64 but should be increased if the ROMFS volume were to be become large. Any value selected must be a power of 2. config NSH_ARCHROMFS bool "Architecture-specific ROMFS header" default n ---help--- Enable this option to provide an architecture-specific ROMFS header at . Note that this header will be copied from nuttx/configs//include and should be stored at this location. config NSH_FATDEVNO int "FAT block device minor number" default 0 depends on FS_FAT ---help--- When the default rcS file used when NSH_ROMFSETC is selected, it will mount a FAT FS under /tmp. This is the minor number of the FAT FS block device. The default is '1' corresponding to /dev/ram1. config NSH_FATSECTSIZE int "FAT sector size" default 512 depends on FS_FAT ---help--- When the default rcS file used when NSH_ROMFSETC is selected, it will mount a FAT FS under /tmp. This is the sector size use with the FAT FS. Default is 512. config NSH_FATNSECTORS int "FAT number of sectors" default 1024 depends on FS_FAT ---help--- When the default rcS file used when NSH_ROMFSETC is selected, it will mount a FAT FS under /tmp. This is the number of sectors to use with the FAT FS. Defualt is 1024.

This is the location where the FAT FS will be mounted. Default is "/tmp". endif # NSH_ROMFSETC if NSH_LIBRARY config NSH_CONSOLE bool "Use console" default y ---help--- If NSH_CONSOLE is set to 'y', then a character driver console front-end is selected (/dev/console). Normally, the serial console device is a UART and RS-232 interface. However, if USBDEV is defined, then a USB serial device may, instead, be used if the one of the following are defined: PL2303 and PL2303_CONSOLE - Set up the Prolifics PL2303 emulation as a console device at /dev/console. CDCACM and CDCACM_CONSOLE - Set up the CDC/ACM serial device as a console device at dev/console. NSH_USBCONSOLE and NSH_USBCONDEV - Sets up some other USB serial device as the NSH console (not necessarily dev/console). config NSH_USBCONSOLE bool "Use a USB console" default n depends on NSH_CONSOLE && USBDEV ---help--- If defined, then the an arbitrary USB device may be used to as the NSH console. In this case, NSH_USBCONDEV must be defined to indicate which USB device to use as the console. config NSH_USBCONDEV string "USB console device" default "/dev/ttyACM0" depends on NSH_USBCONSOLE ---help--- If NSH_USBCONSOLE is set to 'y', then NSH_USBCONDEV must also be set to select the USB device used to support the NSH console. This should be set to the quoted name of a readable/write-able USB driver such as: NSH_USBCONDEV="/dev/ttyACM0". config USBDEV_MINOR int "USB console device minor number" default 0 depends on NSH_USBCONSOLE ---help--- If there are more than one USB devices, then a USB device minor number may also need to be provided. Default: 0 comment "USB Trace Support" config NSH_USBDEV_TRACE bool "Enable Builtin USB Trace Support" default n depends on USBDEV && (DEBUG || USBDEV_TRACE) ---help--- Enable builtin USB trace support in NSH. If selected, buffered USB trace data will be presented each time a command is provided to NSH. The USB trace data will be sent to the console unless DEBUG set or unless you are using a USB console. In those cases, the trace data will go to the SYSLOG device. If not enabled, the USB trace support can be provided by external logic such as apps/system/usbmonitor. if NSH_USBDEV_TRACE config NSH_USBDEV_TRACEINIT bool "Show initialization events" default n ---help--- Show initialization events config NSH_USBDEV_TRACECLASS bool "Show class driver events" default n ---help--- Show class driver events config NSH_USBDEV_TRACETRANSFERS bool "Show data transfer events" default n ---help--- Show data transfer events config NSH_USBDEV_TRACECONTROLLER bool "Show controller events" default n ---help--- Show controller events config NSH_USBDEV_TRACEINTERRUPTS bool "Show interrupt-related events" default n ---help--- Show interrupt-related events endif # NSH_USBDEV_TRACE config NSH_ALTCONDEV bool "Alternative console device" default n depends on NSH_CONSOLE && !NSH_USBCONSOLE && !NSH_TELNET ---help--- If CONFIG_NSH_CONSOLE is set to y, then CONFIG_NSH_ALTCONDEV may also be selected to enable use of an alternate character device to support the NSH console. If CONFIG_NSH_ALTCONDEV is selected, then NSH_CONDEV must be set to select the serial device used to support the NSH console. This may be useful, for example, to separate the NSH command line from the system console when the system console is used to provide debug output. Default: stdin and stdout (probably "/dev/console") NOTE 1: When any other device other than /dev/console is used for a user interface, (1) linefeeds (\n) will not be expanded to carriage return / linefeeds (\r\n). You will need to set your terminal program to account for this. And (2) input is not automatically echoed so you will have to turn local echo on. NOTE 2: This option forces the console of all sessions to use NSH_CONDEV. Hence, this option only makes sense for a system that supports only a single session. This option is, in particular, incompatible with Telnet sessions because each Telnet session must use a different console device. if NSH_ALTCONDEV config NSH_CONDEV string "Alternative console device name" default "/dev/console" ---help--- If CONFIG_NSH_CONSOLE is set to y, then CONFIG_NSH_ALTCONDEV may also be selected to enable use of an alternate character device to support the NSH console. If CONFIG_NSH_ALTCONDEV is selected, then NSH_CONDEV must be set to select the serial device used to support the NSH console. This should be set to the quoted name of a readable/write-able character driver such as: NSH_CONDEV="/dev/ttyS1". This is useful, for example, to separate the NSH command line from the system console when the system console is used to provide debug output. Default: stdin and stdout (probably "/dev/console") NOTE 1: When any other device other than /dev/console is used for a user interface, (1) linefeeds (\n) will not be expanded to carriage return / linefeeds (\r\n).

This option is, in particular, incompatible with Telnet sessions because each Telnet session must use a different console device. endif # NSH_ALTCONDEV config NSH_ARCHINIT bool "Have architecture-specific initialization" default n ---help--- Set if your board provides architecture specific initialization via the board-specific function nsh_archinitialize(). This function will be called early in NSH initialization to allow board logic to do such things as configure MMC/SD slots. config NSH_TELNET bool "Use Telnet console" default n if DEFAULT_SMALL default y if !DEFAULT_SMALL depends on NETUTILS_TELNETD ---help--- If NSH_TELNET is set to 'y', then a TELENET server front-end is selected.
