Add a Serial tab to the Monitor and select the connection that matches your firmware. Ask Embedder to inspect existing output or wait for a specific event.
UART
Use UART for a board’s serial logs or command console. The guide covers wiring, port selection, baud rate, newline settings, and deliberate reset actions.
SEGGER RTT
Use SEGGER RTT for firmware logging buffers accessed through a debug probe. Follow its J-Link or bridge setup and distinguish output up channels from input down channels.
ITM and SWO
Use ITM and SWO for Cortex-M software stimulus output. It requires compatible firmware, SWO wiring, and OpenOCD clock/target settings. It is read-only.
XMOS xSCOPE
Use XMOS xSCOPE for a selected .xe on an xTAG or simulator. A fresh Monitor connection launches that application. The dedicated guide covers .embedder/xmos.json, existing-console reuse, and conditional host input.
Read history without reconnecting
Use live monitoring to wait for new output, and history for output already captured. State the duration or stop string in a live request.
Troubleshoot
- Port missing: check the cable, driver, target power, and selected hardware host.
- Connected but silent: check the matching transport guide’s firmware, channel, and clock requirements.
- Target state matters: keep the existing connection and inspect history before opening a new transport or resetting the target.
