# Virtual UART RTT driver option
drivers: serial: uart_rtt: Virtual UARTs over RTT channels Add support for virtual UART device that uses Segger RTT channels for data transfers. Due to the RTT principle, this driver supports only polling API. Signed-off-by: Pavel Kral <pavel.kral@omsquare.com>

help
This option enables access RTT channel as UART device.
if UART_RTT
drivers: serial: uart_rtt converted to devicetree Instantiate RTT UART instances from devicetree nodes instead of from Kconfig symbols. While RTT is implemented using software, not hardware, it is emulating a hardware device, and thus should be configured through devicetree. This allows the simulated UART device to be selected via devicetree aliases and chosen nodes. The following devicetree snippet will instantiate RTT channels 0 and 2 as UART devices. ``` / { rtt0: rtt_terminal { compatible = "segger,rtt-uart"; label = "rtt_terminal"; status = "okay"; }; rtt2: rtt_secondary { compatible = "segger,rtt-uart"; label = "rtt_app_specific"; status = "okay"; }; }; ``` Fixes the RTT portion of #10621.
