Arm DS-5 Arm DSTREAM User Guide : Restoring a DSTREAM unit that fails to boot

Restoring a DSTREAM unit that fails to boot

You must perform a hardware reset and a firmware update if your DSTREAM unit fails to boot.


  1. Press and hold the reset button on the DSTREAM unit for approximately 10 seconds.
  2. When the STATUS LED flashes red, release the button. The unit is now in recovery mode, and the STATUS LED flashes alternately red and green.
  3. Use the installed Update utility to install a working firmware. The unit then reboots into normal mode.



While in recovery mode, debug and trace operations are not enabled. You must perform a firmware update to restore full functionality.
