4.1. MAC EEPROM

At the time of manufacturing, Intel programs the MAC address EEPROM with the Intel Ethernet Controller XL710-BM2 MAC addresses. The Intel® MAX® 10 accesses the addresses in the MAC address EEPROM through the I2C bus.

Discover the MAC address using the following command: 
$ sudo fpgainfo mac

The MAC Address EEPROM only contains the starting 6-byte MAC address at address 0x00h followed by the MAC address count of 08. The starting MAC address is also printed on the label sticker on the back side of the Printed Circuit Board (PCB).

The OPAE driver provides sysfs nodes to obtain the starting MAC address from the following location: /sys/class/fpga/intel-fpga-dev.*/intel-fpga-fme.*/spi-altera.*.auto/spi_master/spi*/spi*/mac_address

Starting MAC Address Example: 
644C360F4430

The OPAE driver obtains the count from the following location: /sys/class/fpga/intel-fpga-dev.*/intel-fpga-fme.*/spi-altera.*.auto/spi_master/ spi*/spi*/mac_count

MAC count Example: 
08

From the starting MAC address, the remaining seven MAC addresses are obtained by sequentially incrementing the Least Significant Byte (LSB) of the starting MAC Address by a count of one for each subsequent MAC address.

Subsequent MAC address example: 
644C360F4431
644C360F4432
