menuconfig CONSOLE
bool
prompt "Console drivers"
if CONSOLE
config CONSOLE_INPUT_MAX_LINE_LEN
int "Console maximum input line length"
default 128
help
This option can be used to modify the maximum length a console input
can be.
config CONSOLE_HAS_DRIVER
bool
default n
help
This is an option to be enabled by console drivers to signal
that some kind of console exists.
config CONSOLE_HANDLER
bool
prompt "Enable console input handler"
depends on UART_CONSOLE
select UART_INTERRUPT_DRIVEN
default n
help
This option enables console input handler allowing to write simple
interaction between serial console and the OS.
config UART_CONSOLE
bool
prompt "Use UART for console"
default n
depends on SERIAL && SERIAL_HAS_DRIVER
select CONSOLE_HAS_DRIVER
help
Enable this option to use one UART for console. Make sure
CONFIG_UART_CONSOLE_ON_DEV_NAME is also set correctly.
config UART_CONSOLE_ON_DEV_NAME
string "Device Name of UART Device for UART Console"
default "UART_0"
depends on UART_CONSOLE
help
This option specifies the name of UART device to be used for
UART console.
config UART_CONSOLE_INIT_PRIORITY
int
prompt "Init priority"
default 60
depends on UART_CONSOLE
help
Device driver initialization priority.
Console has to be initialized after the UART driver
it uses.
config UART_CONSOLE_DEBUG_SERVER_HOOKS
bool
prompt "Debug server hooks in debug console"
default n
depends on UART_CONSOLE
help
This option allows a debug server agent such as GDB to take over the
handling of traffic that goes through the console logic. The debug
server looks at characters received and decides to handle them itself if
they are some sort of control characters, or let the regular console
code handle them if they are of no special significance to it.
config USB_UART_CONSOLE
bool
prompt "Use USB port for console outputs"
depends on SERIAL
select CONSOLE_HAS_DRIVER
select USB_CDC_ACM
default n
help
Enable this option to use the USB UART for console output. The output
can be viewed from the USB host via /dev/ttyACM* port. Note that console
inputs from the USB UART are not functional yet. Also since the USB
layer currently doesn't support multiple interfaces, this shouldn't be
selected in conjunction with say USB Mass Storage.
config USB_UART_DTR_WAIT
bool
prompt "Wait on DTR control signal"
default n
depends on USB_UART_CONSOLE
help
Enable this option to use flow control on the console. The uart console
waits until the DTR is asserted by the host.
Note: Disabling this might lead to missing console prints.
config RAM_CONSOLE
bool
prompt "Use RAM console"
select CONSOLE_HAS_DRIVER
default n
help
Emit console messages to a RAM buffer "ram_console" which can
be examined at runtime with a debugger. Useful in board bring-up
if there aren't any working serial drivers.
config RAM_CONSOLE_BUFFER_SIZE
int "Ram Console buffer size"
default 1024
depends on RAM_CONSOLE
help
Size of the RAM console buffer. Messages will wrap around if the
length is exceeded.
config RTT_CONSOLE
bool
prompt "Use RTT console"
depends on HAS_SEGGER_RTT
select CONSOLE_HAS_DRIVER
default n
help
Emit console messages to a RAM buffer that is then read by the
Segger J-Link software and displayed on a computer in real-time.
Requires support for Segger J-Link on the companion IC onboard.
config IPM_CONSOLE_SENDER
bool
prompt "Inter-processor Mailbox console sender"
select CONSOLE_HAS_DRIVER
default n
help
Enable the sending side of IPM console
config IPM_CONSOLE_RECEIVER
bool
prompt "Inter-processor Mailbox console receiver"
select RING_BUFFER
default n
help
Enable the receiving side of IPM console
config IPM_CONSOLE_STACK_SIZE
int
prompt "Stack size for IPM console receiver thread"
depends on IPM_CONSOLE_RECEIVER
default 512
help
Each instance of the IPM console receiver driver creates a worker
thread to print out incoming messages from the remote CPU. Specify the
stack size for these threads here.
config IPM_CONSOLE_INIT_PRIORITY
int
prompt "IPM console init priority"
default 60
depends on IPM_CONSOLE_SENDER || IPM_CONSOLE_RECEIVER
help
Device driver initialization priority.
Console has to be initialized after the IPM subsystem
it uses.
config UART_PIPE
bool
prompt "Enable pipe UART driver"
select UART_INTERRUPT_DRIVEN
default n
help
Enable pipe UART driver. This driver allows application to communicate
over UART with custom defined protocol. Driver doesn't inspect received
data (as contrary to console UART driver) and all aspects of received
protocol data are handled by application provided callback.
config UART_PIPE_ON_DEV_NAME
string "Device Name of UART Device for pipe UART"
default "UART_0"
depends on UART_PIPE
help
This option specifies the name of UART device to be used
for pipe UART.
config XTENSA_SIM_CONSOLE
bool
prompt "Use Xtensa simulator console"
depends on SIMULATOR_XTENSA
select CONSOLE_HAS_DRIVER
default y
help
Use simulator console to print messages.
config XTENSA_CONSOLE_INIT_PRIORITY
int
prompt "Init priority"
default 60
depends on XTENSA_SIM_CONSOLE
help
Device driver initialization priority.
