Reference Material
LatticeXP2 Bitstream File Format
Table 17-6 shows the format of a LatticeXP2 bitstream. The bitstream consists of a comment field, a header, the
preamble, and the configuration setup, and data.
Note: The data in this table is intended for reference only.
Implement SPI Flash Programming on ispVM System
The LatticeECP2/3 and LatticeXP2 families of FPGA devices are designed to support a JTAG instruction,
PROGRAM_SPI, which when executed, will effectively connect the four SPI interface signals of SPI Flash devices
to four JTAG port signals.

Browse for the JEDEC file.
Click OK to close the device selection menu.
Click GO to program the LatticeXP2 embedded Flash. For embedded programming, skip this step. Go to
step 7 to generate the VME file instead.
This is optional. For embedded programming, use the VME file generator to generate the VME file first then
run the VME file to program the LatticeXP2 embedded Flash device then port the ispVME driver onto the
embedded system.
