This document lists the non-volatile memories on the FreeForm/PCI-104, their purpose, and how they can be erased.
List of Non-Volatile Memories
|Manufacturer||Part Number||Type||Designator||Purpose||Does Removal affect Board Function?||Electrically Write Protected?||Method of Writing and Erasing|
|Micron||M25P32-VMF6P||SPI Flash||U10||FPGA configuration storage||Yes, FPGA would have to always be configured by JTAG||No, Write Protect pin is disabled||Using Xilinx IMPACT tools|
|SPI Flash||U11||Embedded software code storage, to be used by MicroBlaze or Power PC||Only if you are trying to use MicroBlaze or Power PC||No, Write Protect pin is disabled||Using reference design provided by CTI, including FPGA & host software.|
|Atmel||AT93C66A-10SU-2.7||EEPROM||U9||PLX9056 configuration storage. Sets the size of PCI memory windows and other functions||No, by default the FPGA configures the PLX9056 directly over the local bus||No, Write Protect pin is disabled||Using PLX Software Development kit GUI tool PLX Mon
Using reference design provided by CTI, including FPGA & host software.
|EEPROM||U14||General FPGA parameters, like MAC address||No, MAC address can be hardcoded in the FPGA code||No, Write Protect pin is disabled||Using reference design provided by CTI, including FPGA & host software.|
