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.

Prerequisites

Debug hardware drivers are provided with Arm® Development Studio. You must have 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.

    Note

    When in recovery mode, debug and trace operations are not enabled.

After the recovery process is complete, DSTREAM-ST automatically reboots with its factory settings.

If a restore fails, contact Arm support.

Next Steps

You must perform a firmware update to restore full functionality.

To update the firmware to the latest version, see Update the DSTREAM-ST firmware.
