Troubleshooting

5.2 DSTREAM-XT overheats

The air intakes on the top of both the DSTREAM-ST unit and XT probe must remain clear of any

obstructions.

Air intakes are blocked

If the air intake on the top of the DSTREAM-ST unit becomes blocked and the DSTREAM-ST unit

overheats, it shuts down, all the LEDs turn oﬀ, and it remains in a safe state.

If the air intake on the top of the XT probe becomes blocked and the XT probe overheats, it enters

a low-power mode and its

Solution

Check that the air intakes are clear, and then press

Reset

on the rear of the DSTREAM-ST unit to

reinitialize the DSTREAM-XT system.

5.3 Restore a DSTREAM-XT system

Use the recovery mode in DSTREAM-ST to restore your DSTREAM-XT system back to its factory

settings. If the other troubleshooting steps did not help, the recovery mode is useful to recover

your DSTREAM-XT system.

Before you begin

• Connect and power-up the DSTREAM-XT system. For more information on how to connect

and power-up the DSTREAM-XT system, see

Connect and power up the DSTREAM-XT system

• Attempt a soft reset of your DSTREAM-XT system, by pressing the

Reset

button on the rear of

the DSTREAM-ST unit, before running a full restore of the system.

• Debug hardware drivers are provided with Arm

Development Studio. You must have

Arm Development Studio installed on your host computer to access the drivers. For more

information on installing Arm Development Studio, see the

Arm Development Studio Getting

Started Guide

Procedure

1. Press and hold the reset button on the DSTREAM-ST unit for approximately 10 seconds.
2. When the

STATUS

LED ﬂashes

red

, release the button.

The DSTREAM-ST unit erases the current ﬁrmware in its internal ﬂash, and replaces it with the

original factory-installed version of the ﬁrmware.

When in recovery mode, debug and trace operations are disabled.
