The 'Golden' bitstream image must be located starting at SPI address 0x010000.
If using Lattice ispVM System 18.0 or later, the starting address for the bitstream is entered in the "Starting Address" box of the 'SPI Serial Flash Device' dialog box. (When choosing 'SPI Flash Programming' in the 'Device Information' dialog, click 'SPI Flash Options' to open the 'SPI Serial Flash Device' dialog.)
ispVM System does not support SPI Flash Programming for the MachXO2 devices prior to the release of ispVM System version 18.0.
