Part 2: Program the Primary Pattern into LatticeXP2 Embedded Flash
Follow the procedures shown in Figure 17-3 and Table 17-5 too program the JEDEC file into the LatticeXP2
embedded Flash using the ispVM System. There is absolutely no difference between programming the LatticeXP2
device for standard single boot and dual boot applications.
For live field upgrade of a mission critical application, Background Mode programming is strongly recommended.
For more details on Background Mode programming mode for mission critical application, please refer to the
LatticeXP2 Mission Critical Field Upgrade Usage Guide. Contact Lattice Applications for the document if required.
Once the embedded Flash and Done fuse is programmed, it can be difficult to configure the LatticeXP2 device from
the external SPI Flash device. There are two methods that can be used to test the dual boot feature does work.
Figure 17-3. Using ispVM to Program a JEDEC into the Embedded Flash
1. Drive the CFG1 pin to 0. This will cause the bitstream in the SPI Flash to be the Primary pattern.
2. Use the ERASE_DONE command to erase only the Done fuse of the LatticeXP2 Embedded Flash. The
only draw back of this approach is that entire LatticeXP2 Embedded Flash will need to be re-programmed.
Simply programming the Done fuse will not work.
