2.1 VPP Must Be Set to 2.5V When Programming or Writing the eNVM at Industrial Temperature Range

VPP can be set to 2.5V or 3.3V. However, when writing or programming the eNVM of Revision 0 of the M2GL005, M2GL010, and M2GL025 devices below 0 °C, VPP must be set to 2.5V.

For the VPP minimum and maximum settings, see the DS0128:IGLOO 2 FPGA and SmartFusion 2 SoC FPGA Datasheet. The eNVM reading, with VPP set to 3.3V or 2.5V, operates as intended.
