2.3.3 Serial log

The serial path shows boot logs from a device wired to your PC—useful when boot fails, the network is unreachable, or you need to watch the startup sequence.

Serial does not add the device to the device list. It does not enable file ops, Moss device actions, or OpenClaw automatically.

What serial can do

CapabilitySupported?
View boot and console outputYes
Help rescue devices with no networkYes
Shell access for manual fixesDepends on serial login being enabled
Save as an RDK Studio deviceNo
Files, remote desktop, code editorNo—use SSH
Moss device toolingNo—use SSH

If the UI does not expose serial, follow on-screen guidance.

Steps

  1. Connect the debug cable to the RDK debug port or a USB-UART adapter.
  2. Confirm the OS sees the serial device.
  3. Open Add device → Local serial log, or use the local serial strip on Terminal.
  4. Click Add and authorize the port in the system prompt.
  5. Pick the baud rate and click Connect.

115200 is common on RDK debug ports. If you see garbled text, try other rates per board docs.

Common issues

SymptomWhat to do
Empty dropdownClick Add and authorize the port in the OS dialog
OS sees port but Studio does notRefresh the list; pick the matching COM/tty
Ports show as unknownClick Clear unknown ports and add again
Open failedAnother app may hold the port; close it and retry
Garbled outputAdjust baud rate; check RX/TX/GND wiring

Next steps

Serial only helps until the device can boot and reach the network or SSH. After that, return to 2.3.2 Add device via SSH to add it properly.
