HDR-60 Base Board – Revision B
Configuring/Programming the Board
Requirements
• PC with Lattice ispVM System software version 17.9 (or later) installed with USB driver.
Note: An option to install this driver is included as part of the ispVM System setup.
For a complete discussion of the LatticeECP3 configuration and programming options, refer to the
LatticeECP3
sysCONFIG Usage Guide

Download Procedures for the Lattice HDR-60 Base Board
The download instructions described below show how to download bitstreams into the LatticeECP3 SRAM using
the ispVM System software. Downloads can be either direct through a cable connection to a PC, or indirect by first
programming the on-board SPI Flash and then downloading the bitstream to the LatticeECP3 SRAM from SPI
Flash. You can download bitstreams through a download cable to the LatticeECP3 SRAM at any time. After a bit-
stream has been downloaded to SPI Flash, you can download the bitstream from SPI Flash to the LatticeECP3
SRAM by cycling the power to the evaluation board.
The Lattice HDR-60 Base Board provides support for two types of download cable connections: a standard USB-A
to USB-A cable at J12, or a Lattice ispDOWNLOAD cable (USB type or parallel port type with flywire connections)
at J3 as described in Appendix C. Given that you might want to download to either the LatticeECP3 SRAM or the
SPI Flash, separate LatticeECP3 download procedures will follow that cover each type of download.
Note that the first download procedure shows the menus as viewed on a Windows XP operating system. Follow-on
download procedures are very similar and do not show the menus.
LatticeECP3 SRAM Configuration Using a Standard USB Cable at J12
The LatticeECP3 SRAM can be configured easily using the ispVM System software to download a bitstream via a
standard USB-A to USB-A cable. The LatticeECP3 device is SRAM based, so it must remain powered on to retain
its configuration when programming the SRAM.
1.
Attach a ground connection from test equipment chassis ground to the ground plane of the board, for example,
on the metal HDMI connector.
2.
Connect the USB-A to USB-A cable from your PC’s USB connector to the upper USB port on J12 on the HDR-
60 Base Board.
3.
Connect the 12 V wall power adaptor cable to J10 and check to see that the wall power adapter is plugged in to
a 120 VAC source.
4.
Start the ispVM System software. Select the menu items
Options > Autoscan Options > Custom Scan
as
shown in Figure 4.
