- The firmware for this processor can be stored in its own dedicated IIC EEPROM (U17), download via J27
- Xilinx XCF32P Platform Flash Configuration Storage Device
- The Platform Flash memory can be used to program the FPGA using master or slave configuration in serial or parallel (SelectMap) modes. The board is wired up so the Platform Flash memory can download bitstreams in Master Serial, Slave Serial, Master SelectMAP (parallel), or Slave SelectMAP (parallel) modes. Using the iMPACT tool to program the Platform Flash memory, the user has the option to select which of the four modes to use for programming the FPGA. The configuration mode DIP switches on the board must be set to match the programming method being used by the Platform Flash memory.
