- Whether or not the FPGAs are configured (blue DONE LED on/off)
- Whether the Dini Group reference design is loaded in one or more FPGAs (disable/enable
the “FPGA Reference Design” menu)
- Check whether USB is enabled
1.1.2 Disable/Enable USB
To communicate to the FPGA design using USB, the “Main Bus” interface is used. See the
hardware chapter for more information on this interface. Some users elect not to use the Main
Bus for USB communication. To allow these users to make use of the signals in the Main Bus
for their own purposes, the USB Controller is careful not to use the Main Bus unless explicitly
given permission by the user. The user can give permission to use Main Bus by pressing the
“Enable USB->FPGA communication” button. It can revoke that permission by pressing the
“Disable USB->FPGA communication” button. When the DN9002K10PCI powers on, it
begins in the disabled state. The state is stored on the board, so that multiple programs accessing
the DN9002K10PCI may prevent each other from using the Main Bus.
1.1.3 Log Window
This text box prints the result of each user command in USB Controller. There is a “clear log”
button to clear the contents of this text box.
1.1.4 Board Graphic
USB Controller’s main window shows a graphic representing your DN9002K10PCI. The
number of FPGAs that are installed on your board should appear in this graphic. If one or more
FPGAs are configured on the board, a blue LED will glow next to the FPGA in this graphic
window, just like on the actual board hardware itself.
If the USB Controller could not find a DN9002K10PCI connected to any USB port, this
window will appear.
