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).
