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 "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 UART_CONSOLE_INPUT_EXPIRED bool "Support for UART console input expired mechanism" default y depends on UART_CONSOLE && PM help This option allows a notification to the power management module that the module for UART console is in use now. If the interval of console module doesn't receive any input message exceeds expired timeout, such as UART_CONSOLE_INPUT_EXPIRED_TIMEOUT, the power management module is allowed to enter sleep/deep sleep state and turn off the clock of UART console module. This mechanism gives a window in which the users can organize input message if CONFIG_PM is enabled. config UART_CONSOLE_INPUT_EXPIRED_TIMEOUT int "Fixed amount of time to keep the UART console in use flag true" default 15000 depends on UART_CONSOLE_INPUT_EXPIRED help Fixed amount of time which unit is milliseconds to keep the UART console in use flag true. config JAILHOUSE_DEBUG_CONSOLE bool "Use JAILHOUSE_DEBUG console" select CONSOLE_HAS_DRIVER depends on ARM64 help Emit console messages to a jailhouse hypervisor debug console. Useful in board bring-up if there aren't any working serial drivers. 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. endif 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 2048 if COVERAGE_GCOV 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 bool "Inter-processor Mailbox console" depends on IPM select CONSOLE_HAS_DRIVER help Enable console over Inter-processor Mailbox. config IPM_CONSOLE_LINE_BUF_LEN int "IPM console line buffer length" default 128 depends on IPM_CONSOLE help IPM console line buffer length specify amount of the buffer where characters are stored before sending the whole line. config UART_MCUMGR bool "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_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_TRANSPORT_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. config POSIX_ARCH_CONSOLE bool "Use the host terminal for console" depends on ARCH_POSIX select CONSOLE_HAS_DRIVER help Zephyr's printk messages will be directed to the host terminal stdout config POSIX_ARCH_CONSOLE_INIT_PRIORITY int "Init priority" default 99 depends on POSIX_ARCH_CONSOLE help Device driver initialization priority. config SEMIHOST_CONSOLE bool "Use semihosting for console" select CONSOLE_HAS_DRIVER depends on SEMIHOST help Enable this option to use semihosting for console. See SEMIHOST for a more complete description of semihosting. module = UART_CONSOLE module-str = UART console source "subsys/logging/Kconfig.template.log_config" source "drivers/console/Kconfig.gsm_mux" config UART_MUX bool "[DEPRECATED] UART muxing (GSM 07.10) support [EXPERIMENTAL]" depends on SERIAL_SUPPORT_INTERRUPT && GSM_MUX select UART_INTERRUPT_DRIVEN select EXPERIMENTAL select DEPRECATED help Enable this option to create UART muxer that run over a physical UART. The GSM 07.10 muxing protocol is used to separate the data between these muxed UARTs. if UART_MUX config UART_MUX_DEVICE_NAME string "UART mux device name template" default "GSM" help Device name template for the UART mux Devices. First device would have name $(UART_MUX_DEVICE_NAME)_0, etc. User will access muxed UART using this name. config UART_MUX_RINGBUF_SIZE int "UART mux ring buffer size" default 256 help UART mux ring buffer size when passing data from RX ISR to worker thread that will do the unmuxing. config UART_MUX_TEMP_BUF_SIZE int "Size of the temp buffer when reading data from real UART" default 32 help Size of the temporary RX buffer in receiving ISR. config UART_MUX_DEVICE_COUNT int "Number of UART mux devices (DLCIs)" default GSM_MUX_DLCI_MAX range 1 64 help Number of instances of UART muxes. Default value is set by maximum number of DLCIs (Data Link Connection Identifiers) configured in the system. config UART_MUX_REAL_DEVICE_COUNT int "Number of real UART devices" default 1 help Tells how many real UART devices there are. Typically there is only one UART and the muxed UARTs are run on top of that. If you have two modems for example, then you would need to increase this to two. config UART_MUX_RX_STACK_SIZE int "Size of the stack allocated for receiving data from UART" default 512 help Sets the stack size which will be used by the PPP RX workqueue. config UART_MUX_RX_PRIORITY int "RX workqueue thread priority" default 7 help Sets the priority of the RX workqueue thread. module = UART_MUX module-str = UART mux source "subsys/logging/Kconfig.template.log_config" endif # UART_MUX config UART_MUX_VERBOSE_DEBUG bool "Print hexdump of sent and received packets" depends on UART_MUX_LOG_LEVEL_DBG help As there might be lot of debug output printed, only enable this if really needed. config EFI_CONSOLE bool "Use EFI console for console output" select CONSOLE_HAS_DRIVER help Enable this option to use EFI console output. config WINSTREAM_CONSOLE bool "Use Winstream console" depends on WINSTREAM help Use winstream as a console. See the WINSTREAM Kconfig help for more information. endif # CONSOLE
