Make sure CONFIG_UART_CONSOLE_ON_DEV_NAME is also set correctly. if !HAS_DTS 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. endif 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. if !HAS_DTS 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. endif 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 NATIVE_POSIX_CONSOLE bool prompt "Use native stdin/stdout for console" depends on ARCH_POSIX select CONSOLE_HAS_DRIVER default y help Use native stdin and stdout to print messages and get input config NATIVE_POSIX_STDIN_CONSOLE bool prompt "Read from native stdin for console" depends on NATIVE_POSIX_CONSOLE default y help Use native console to get input. config NATIVE_STDIN_POLL_PERIOD int prompt "Polling period for stdin" depends on NATIVE_POSIX_STDIN_CONSOLE default 20 help In ms, polling period for stdin config NATIVE_STDIN_PRIO int prompt "Priority of the stdin polling thread" depends on NATIVE_POSIX_STDIN_CONSOLE default 4 help Priority of the native stdin polling thread config NATIVE_POSIX_STDOUT_CONSOLE bool prompt "Print to native stdout" depends on NATIVE_POSIX_CONSOLE default y help Use native console (stout) to print messages. config XTENSA_CONSOLE_INIT_PRIORITY int prompt "Init priority" default 60 depends on XTENSA_SIM_CONSOLE help Device driver initialization priority. config NATIVE_POSIX_CONSOLE_INIT_PRIORITY int prompt "Init priority" default 60 depends on NATIVE_POSIX_CONSOLE help Device driver initialization priority. source "drivers/console/Kconfig.telnet" endif
