DSTREAM-ST Getting Started Guide

5. Troubleshooting

This chapter describes the steps that you need to take when your DSTREAM-ST unit does not
function as expected.

5.1 DSTREAM-ST overheats

In a powered-up state, the air intake on the top of the DSTREAM-ST unit must remain clear.
Air intake is 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.
Solution
To re-initialize the DSTREAM-ST unit, press the reset button on the rear of the unit.

5.2 Restore a DSTREAM-ST unit

If there are any problems with the DSTREAM-ST unit, you can restore it back to its factory settings
using the recovery mode for the unit.
Before you begin
Debug hardware drivers are provided with Arm
Development Studio installed on your PC to access the drivers.
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.
DSTREAM-ST erases the existing firmware within its internal flash, and replaces it with the
original factory installed version.
When in recovery mode, debug and trace operations are not enabled.
Results
After the recovery process is complete, DSTREAM-ST automatically reboots with its factory
settings.
