A manufacturing EEPROM is connected to the adaptive SoC via the I2C main
interface. See Table 1 for the address. The following table provides the
manufacturing EEPROM register map. Data locations 0–127 are in a write protected
area of the device and are set at time of manufacturing. Data locations 128–255 are
in a re-writable area and can be accessed/modified by the user. The AMI tool can be
used to view EEPROM information using the ami_tool mfg_info and
ami_tool eeprom_rd/eeprom_wr commands.
| Location (Hex) | Location (Dec) | No. of Bytes | Field Name | Stored Format |
|---|---|---|---|---|
| 0 | 0 | 4 | EEPROM Version | ASCII |
| 4 | 4 | 2 | Data Checksum | Literal/Binary |
| 6 | 6 | 36 | Alveo Product Name | ASCII |
| 2A | 42 | 24 | Alveo Part Number | ASCII |
| 42 | 66 | 16 | Manufacturing Alveo Part Number | ASCII |
| 52 | 82 | 5 | Manufacturing Alveo Part Revision | ASCII |
| 57 | 87 | 14 | Product Serial Number | ASCII |
| 65 | 101 | 4 | Manufacturing Date | Literal/Binary |
| 69 | 105 | 1 | Number of MAC IDs | Literal/Binary |
| 6A | 106 | 6 | MAC ID 1 | Literal/Binary |

The following sections provide the description of the various fields. Unless stated, all values must be programmed starting with the MSB at the lowest address (that is, Big Endian method). All the trailing unused bytes in each field must be set to 0xFF at the time of EEPROM programming. For example, the maximum length of Alveo Product Name is 36 bytes. A 24-byte long Alveo Product Name leaves the last 12 bytes set to the default value of 0xFF.
EEPROM Version
Format: (ASCII) NN.N
Up to 4 characters (including ‘.’) when N is numeric, to identify the EEPROM version,
for example, 4.0.
Data Checksum
Format: 2-byte numeric value
Inverted value of the sum of data in locations 6 to 128.
Number of MAC IDs
Format: 1-byte number defining the quantity of MAC IDs
MAC ID 1
Format: 6-byte Hexadecimal notation, for example, AB3241CDAB9F with colons omitted
The number of MAC IDs required is product dependent but fixed and contiguous (as defined in ARDs). The MAC ID 1 field is the mandatory field. Management controller firmware reads the MAC ID 1 field and calculates all the other required MAC IDs using the Number of MAC IDs field and passes on required information via in-band or out-band, as needed.
UUID
Format: 128-bit UUID conforming to UUID V1
Hyphens/dashes in UUID are not encoded into this field.
