Placing the USB560v2 into Safe Mode
The following section describes the process to place the USB560v2 into safe mode.
It is recommended
that this process not be used unless directed by Blackhawk technical support.
The USB560v2 firmware has an internally programmed unsuccessful boot counter. When this counter
reaches 10, the USB560v2 will boot into safe mode. The primary purpose for this counter is to reclaim
use of the emulator should a problem with the application firmware preventing the unit from booting
properly into normal mode.
1.
To enter safe mode, the USB560v2 will need to be power cycled at least 10 times. To do this,
you should first connect the USB cable to the USB560v2.
2.
Then connect the USB cable other end to an available USB port on your PC (Windows or Linux).
After 3-5 seconds, disconnect the USB cable from the port on your PC. We recommend using
the PC’s USB port for this process of connecting and disconnecting the USB cable.
3.
Repeat this process 10-12 times.
4.
Safe mode can be identified when the MODE LED powers on red (see Figure 2).
5.
Once in safe mode, the unit should enumerate properly with Windows or Linux and you can
follow the instructions in the section labeled, “
Updating the Blackhawk USB560v2 Firmware”.
If the USB560v2 fails to enter safe mode after repeated attempts, please contact Blackhawk technical
support.
