Programming With Ispvm; Ispmach 4256Ze Breakout Board - Lattice Semiconductor ispMACH 4256ZE User Manual

Programming with ispVM

A demonstration design is pre-programmed into the Breakout Board by Lattice. To restore a Breakout Board to fac-
tory settings or load an alternative demo design, use the procedures in this section.
To install ispVM programming tools:
1. Install and license ispVM System software.
2. Connect the board to a host PC using the USB port header connection.
3. Follow the USB Cable Interface procedure below to program the evaluation board.
The Breakout Board is equipped with a built-in USB-based programming circuit. This consists of a USB PHY and a
USB connector. When the board is connected to a PC with a USB cable, it is recognized by the ispVM System soft-
ware as a USB Download Cable. The ispMACH 4256ZE can then be scanned and programmed using the ispVM
System software.
To program a demo programming file:
1. From the Start menu run ispVM System.
ispVM appears.
2. Choose Options > Cable and IO Port Setup...
The Cable and I/O Port Setup dialog appears.
3. Make the following selections:
Cable Type: USB2
Port Setting: FTUSB-0
Click OK.
4. Choose ispTools > Scan Chain.
The New Scan Configuration Setup window appears. The LC4256ZE device appears in the device list.
5. Right-click the LC4256ZE entry and choose Edit Device...
The Device Information dialog appears.
6. From the Data File section, click the Browse button.
The Open Data File dialog appears.
7. Browse to the <Demo Dir> folder, select <Demo>.jed, and click Open. From the Operation list choose Erase,
Program, Verify and click OK.
8. Choose Project > Download.
ispVM reprograms the evaluation board.
Programming requires about 10 seconds. A small timer window will appear to show elapsed programming time. At
the end of programming, the configuration setup window should show a "PASS" in the Status column.
