+### Cannot connect UART when debugging
+
+**Symptom**
+
+Using older **DAPLink** or **LPC-Link2** implementations, it is not possible to have a debug connection and monitor the
+output of the UART on the SERIAL MONITOR at the same time. Once the serial connection is opened, the debug connect
+stalls and throws these two errors:
+
+```txt
+Cannot execute this command while the target is running.
+Use the "interrupt" command to stop the target and then try again.
+```
+
+And
+
+```txt
+Unable to read memory.
+```
+
+**Solution**
+
+Using an NXP board with the new MCU-Link FW, this problem does not occur.
+
+For older boards, there is no new DAPLink firmware available. Please avoid using the UART when debugging or use an
+external debug adapter.
