Scan or select the LatticeXP2 device.
Select the SPI Flash Programming under the Device Access Options.
Select the SPI Flash operation from the operation list:
(Note: Due to the operations describe here are all carried out on the JTAG port, as previously noted, the PRO-
GRAMN pin function is disabled by any activities on the JTAG port, power cycling the LatticeXP2 device is the only
way to re-enable the PROGRAMN pin.)

Scan SPI Flash Device
Launch the SPI Flash device menu.
Select the SPI Flash device.
Browse for the bitstream file. Note: Do not change the starting address from sector 0. The LatticeXP2 device will boot
from sector 0.
Click OK to close the SPI Flash device menu.
Click OK to close the device selection menu.
Click GO to program the SPI Flash device. For embedded programming, skip this step. Go to step 10 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 SPI Flash device then port the ispVME driver onto the embedded system.
Comments
This is a Direct Mode operation. The LatticeXP2 device will be forced into an erased
This Direct Mode operation will calculate the fuse checksum in the SPI Flash device
This Direct Mode operation will scan SPI Flash device against the Lattice SPI Flash
state, by clearing (erase) the SRAM fuses, before and while programming the SPI
Flash device. The purpose is to set the persistent fuse to be on to gain unconditional
access to the SPI Flash device through the JTAG port.
This is a Background Mode operation. The LatticeXP2 device can remain functional
while programming the SPI Flash device. However, the persistent fuse in the
LatticeXP2 device must be set to on first to use this operation. If the persistent fuse
is not set to be on or the LatticeXP2 device is not blank, this operation will fail ID
check. In that case, must use the operation above instead.
disabled by the JTAG port activities. Must use this operation if need to boot the bit-
stream into the LatticeXP2 device immediately after completing the SPI Flash pro-
gramming. Refresh = the JTAG refresh instruction which has the effect as toggling
the PROGRAMN pin.
This Direct Mode operation will erase and program the SPI Flash device in without
verification in Direct Mode. The VME file size of this operation is half that of with ver-
ification. User might have no choice but use this operation when the EPROM size
storing the VME file is too small to include verification.
Same as above except it is conducted in Background Mode. The persistent fuse in
the LatticeXP2 device must be on for this operation to work.
per the starting address and ending address after browsing in the bitstream file at
step 6 below. Example: The XP2-5E bitstream occupy sector 0, 1, and 2, or three
sectors total. The checksum is calculated by reading the fuse data out from those
three occupied sectors.
This Direct Mode operation will calculate the fuse checksum of the entire SPI Flash
device. Example: The 2Mb SPI Flash device has four sectors total. The checksum is
calculated by reading out fuse data from all four sectors
device database. If there is a match, then it shows what the device is on the mes-
sage window for user to enter on step 6. If it is not in the database, then it returns an
unknown device. User will need to find out the SPI Flash device name manually then
select accordingly at step 6.
