This document provides detail technical explanation of the dual boot feature in the LatticeXP2 device family. The
application details for using ispVM and ispVME to support dual boot feature during the different applications is as
follows:
The application of the LatticeXP2 Advanced Security feature, TransFR feature, and Mission Critical Field Upgrade
are briefly mentioned in this document. The details can be found in the LatticeXP2 Advanced Security Configura-
tion, LatticeXP2 TransFR Feature, and LatticeXP2 Mission Critical Field Upgrade Usage Guides, respectively. Con-
tact Lattice Applications for the other documents if required.
Note: The LatticeXP2 devices only support encrypted JEDEC files, which target the embedded Flash of the
LatticeXP2 devices.

Resource
The minimum SPI Flash density required to support the dual boot feature is listed in Table 17-1.
Table 17-1. Required SPI Flash Device Size
1. Use ispVM or ispVME to program the bitstream into the SPI Flash device
2. Use ispVM or ispVME to program the JEDEC file into the LatticeXP2 device.
