CONFIG_LOG_BACKEND_RTT
¶
Enable Segger J-Link RTT backend
Type: bool
Help¶
When enabled, backend will use RTT for logging. This backend works on a per message basis. Only a whole message (terminated with a carriage return: ‘r’) is transferred to up-buffer at once depending on available space and selected mode. In panic mode backend always blocks and waits until there is space in up-buffer for a message and message is transferred to host.
