Figure 15-3. ispVM Main Window
First, create the desired files using ispLEVER or Diamond. Depending on the application, these files might be the
same design or different designs. There is nothing special about these files, in other words they contain all of the
information needed to fully configure the FPGA.
Next, open ispVM (see Figure 15-3), do a scan of the board by clicking on the SCAN button on the toolbar, and
then double click on the row in the chain that has the LatticeECP2/M. You will now see the Device Information win-
dow (see Figure 15-4).
Figure 15-4. Device Information Window
From the Device Options drop-down box select Dual Boot SPI Flash Programming. Then click on the SPI Flash
Options button to open the SPI Serial Flash Device window (see Figure 15-5). In this window click on Select and
choose the SPI Flash that’s mounted on the board.
