Blackhawk USB560v2 Operating Mode Details and Instructions
The following document describes the operating modes of the Blackhawk USB560v2 STM emulator
(USB560v2). It also covers instructions for debugging and maintaining the device’s firmware that may
not be covered in the installation guide.
Operating Modes
The USB560v2 has two operating modes, normal and safe. Both modes are described in the following
two sections.
Normal Mode
The typical mode of operation (or Normal Mode) of the USB560v2 is the default boot mode. This will
allow the USB560v2 to enumerate with Microsoft Windows or be detected on Linux systems. In this
mode all JTAG functions are enabled.
During boot, normal mode can be detected via the two, bi-color USB560v2’s LEDs. On power up, during
the 20 second boot process, the USB LED will be red to start and turn green upon successful
enumeration with Windows or Linux. The MODE LED will blink green on and off during the boot
process.
Once the boot process has completed both LEDs will be a steady green (see Figure 1).

Safe Mode
The USB560v2 is running an embedded version of the Linux operating system. Safe mode is a protected
version of Linux the runs from a different location than normal mode. It is a safeguard in case the
USB560v2 cannot boot into normal mode. It is also used to update the USB560v2 with new application
firmware when necessary.
Corrupted flash, for example, may prevent the USB560v2 from booting into normal mode. While rare,
this could be caused by ESD, ground loops, or electrical surges during power up or power down. Placing
the USB560v2 into safe mode can allow end users to fix the corrupt flash.
Safe mode can also be entered when the USB560v2 is powered on 10 or more times without completing
the boot process. This is covered in more detail in the section, “Placing the USB560v2 into Safe Mode”.
Safe mode can be detected upon power up and during the 20 second boot period when the MODE LED
is solid red. Once the boot process has completed the MODE LED will blink red on and off (see Figure 2).

Unknown Mode
While the USB560v2 has two modes, it is possible for the device to enter an unknown mode. Should this
happen, it is recommended that you contact Blackhawk technical support or try to take the steps to
place the unit into safe mode and update the unit’s firmware.

Updating the Blackhawk USB560v2 Firmware
The following section describes the steps to update the application firmware for the USB560v2.
It is important to note that updating the firmware should only be done if required or instructed by
Blackhawk technical support.
1. Connect the emulator to your computer and confirm it has powered up and enumerated with
Windows or Linux. For Windows, the USB560v2 should be visible in the Blackhawk Control
Panel Window (see Figure 7). If developing on Linux, use the lsusb command in a terminal
window (see Figure 3). The USB560v2 will be identified by the id 0b1e:0009.
2. Start the Bh560v2 Configuration utility. The icon (Figure 4) should be located on the desktop.
Once started the utility should identify the USB560v2. Highlight the entry in the devices section
at the top (refer to Figure 5).
3. Press the “Update…” button highlighted in Figure 5. This will display a File Selection Dialog.
Using the dialog’s controls, browse to the folder with the updated firmware. As of this writing
the file name and version is USB560v2_firmware_5.0.573.0. Depending on the CCS
version installed, the path to the file will be similar to:
<ccs>\ccs_base\emulation\Blackhawk\Bh560v2\firmware
It is important that you select the proper firmware file or the device may be rendered useless.
The proper file will contain USB560v2 in the name. Do not use the xds560 or mezzanine
firmware files. Once the correct file is selected the update process will take over and update
the USB560v2. When completed the output log will indicate “Done”in the output.
If you have any problems or question before, during or after the update process, please contact
Blackhawk technical support.

Placing the USB560v2 into Normal Mode
The following section describes the process to place the USB560v2 into normal mode.
1. Connect the emulator to your computer and confirm it has powered up and enumerated with
Windows or Linux. For Windows, the USB560v2 should be visible in the Blackhawk Control
Panel Window (see Figure 7). If developing on Linux, use the lsusb command in a terminal
window (see Figure 3). The USB560v2 will be identified by the id 0b1e:0009.
2. Start the Bh560v2 Configuration utility. The icon (Figure 4) should be located on the desktop.
Once started the utility should identify the USB560v2. Highlight the entry in the devices section
at the top (refer to Figure 6).
3. Once the unit is highlighted and the utility confirms safe mode, the Clear Safe Mode
button will be enabled.
4. Press the Clear Safe Mode button and the unit will be reset for normal mode. This process
will reboot the unit and may take 20 seconds to complete.

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.
