4.4.3 Writing to the eNVM Block
Writing to eNVM by using the Cortex-M3 processor can be done by the API provided in the eNVM driver. The eNVM driver is available in the Firmware Catalog. FPGA fabric user logic can implement the state machine to write into the eNVM by implementing the commands sequence explained in the eNVM commands section.
For information about reading and writing to the eNVM block using the Cortex-M3, see AC391: SmartFusion2 SoC FPGA - eNVM Initialization Application Note.
