config UART_CONSOLE_ON_DEV_NAME
string "Device Name of UART Device for UART Console"
default "$(dt_str_val,DT_UART_CONSOLE_ON_DEV_NAME)" if HAS_DTS
default "UART_0"
depends on (UART_CONSOLE || CONSOLE_SUBSYS)
help
This option specifies the name of UART device to be used for
UART console.
menuconfig CONSOLE
bool "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
help
This is an option to be enabled by console drivers to signal
that some kind of console exists.
config CONSOLE_HANDLER
bool "Enable console input handler"
depends on UART_CONSOLE
select UART_INTERRUPT_DRIVEN
help
This option enables console input handler allowing to write simple
interaction between serial console and the OS.
config UART_CONSOLE
bool "Use UART for console"
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_INIT_PRIORITY
int "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 "Debug server hooks in debug console"
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 UART_CONSOLE_MCUMGR
bool "Enable UART console mcumgr passthrough"
depends on UART_CONSOLE
help
Enables the UART console to receive mcumgr frames for image upgrade
and device management. When enabled, the UART console does not
process mcumgr frames, but it hands them up to a higher level module
(e.g., the shell). If unset, incoming mcumgr frames are dropped.
config USB_UART_CONSOLE
bool "Use USB port for console outputs"
select UART_CONSOLE
select USB_CDC_ACM
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 "Wait on DTR control signal"
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 "Use RAM console"
select CONSOLE_HAS_DRIVER
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 "Use RTT console"
depends on USE_SEGGER_RTT
select CONSOLE_HAS_DRIVER
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.
if RTT_CONSOLE
config RTT_TX_RETRY_CNT
int "Number of TX retries"
default 2
help
Number of TX retries before dropping the byte and assuming that
RTT session is inactive.
config RTT_TX_RETRY_DELAY_MS
int "Delay between TX retries in milliseconds"
default 2
help
Sleep period between TX retry attempts. During RTT session, host pulls data
periodically. Period starts from 1-2 milliseconds and can be increased
if traffic on RTT increases (also from host to device). In case of
heavy traffic data can be lost and it may be necessary to increase
delay or number of retries.
config RTT_TX_RETRY_IN_INTERRUPT
bool "Busy wait in the interrupt context for TX retry"
help
If enabled RTT console will busy wait between TX retries when console
assumes that RTT session is active. In case of heavy traffic data can
be lost and it may be necessary to increase delay or number of
retries.

config IPM_CONSOLE_SENDER
bool "Inter-processor Mailbox console sender"
select CONSOLE_HAS_DRIVER
help
Enable the sending side of IPM console
config IPM_CONSOLE_RECEIVER
bool "Inter-processor Mailbox console receiver"
select RING_BUFFER
help
Enable the receiving side of IPM console
config IPM_CONSOLE_STACK_SIZE
int "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 "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 "Enable pipe UART driver"
select UART_INTERRUPT_DRIVEN
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 "$(dt_str_val,DT_UART_PIPE_ON_DEV_NAME)" if HAS_DTS
default "UART_0"
depends on UART_PIPE
help
This option specifies the name of UART device to be used
for pipe UART.
config UART_MCUMGR
bool "Enable mcumgr UART driver"
select UART_INTERRUPT_DRIVEN
help
Enable the mcumgr UART driver. This driver allows the application to
communicate over UART using the mcumgr protocol for image upgrade and
device management. The driver doesn't inspect received data (as
contrary to console UART driver) and all aspects of received protocol
data are handled by an application provided callback.
if UART_MCUMGR
config UART_MCUMGR_ON_DEV_NAME
string "Device Name of UART Device for mcumgr UART"
default "$(dt_str_val,DT_UART_MCUMGR_ON_DEV_NAME)" if HAS_DTS
default "UART_0"
help
This option specifies the name of UART device to be used
for mcumgr UART.
config UART_MCUMGR_RX_BUF_SIZE
int "Size of receive buffer for mcumgr fragments received over UART, in bytes"
default 128
help
Specifies the size of the mcumgr UART receive buffer, in bytes. This
value must be large enough to accommodate any line sent by an mcumgr
client.
config UART_MCUMGR_RX_BUF_COUNT
int "Number of receive buffers for mcumgr fragments received over UART"
default 2
help
Specifies the number of the mcumgr UART receive buffers. Receive
buffers hold received mcumgr fragments prior to reassembly. This
setting's value must satisfy the following relation:
UART_MCUMGR_RX_BUF_COUNT * UART_MCUMGR_RX_BUF_SIZE >=
MCUMGR_SMP_UART_MTU
endif # UART_MCUMGR
config XTENSA_SIM_CONSOLE
bool "Use Xtensa simulator console"
depends on SIMULATOR_XTENSA
select CONSOLE_HAS_DRIVER
default y
help
Use simulator console to print messages.

depends on ARCH_POSIX
select CONSOLE_HAS_DRIVER
help
Use the host terminal (where the native_posix binary was launched) for the
Zephyr console
config NATIVE_POSIX_STDIN_CONSOLE
bool "Use the host terminal stdin"
depends on NATIVE_POSIX_CONSOLE
