  7. 4Revision History

2.4.3 SEEPROM Header

Each of the AM572x IDK EVMs has a unique serial number. This serial number is printed on a sticker attached to the IDK and it is programmed into a SEEPROM memory device connected to the AM5728 processor over the I2C bus. The SEEPROM also contains board details such as board type, version, configuration, and so on. This information is stored in a structure at the beginning of the SEEPROM in a known format that can be read by the application software. These values are all stored with the first character or MSB stored at the lowest addressable location in each field. Table 2-3 lists all of the fields in this header definition.

NameSize (bytes)Contents
Header4MSB 0xEE3355AA LSB
Board Name8Name for board in ASCII “AM572” = AM572x Industrial Development Kit EVM.
Version4Hardware version code for board in ASCII “1.3A” = revision 01.3A
Serial Number12Serial number of the board. This is a 12-character string that is: WWYY4P47nnnn, where WW = 2 digit week of the year of production, YY = 2 digit year of production,
nnnn = incrementing board number.
Configuration Option32Codes to show the configuration setup on this board. Reserved.
Ethernet MAC Address #06Ethernet MAC Address #0 assigned to the AM572x IDK EVM. This is the first of a block of addresses available for the Industrial Interface ports.
Ethernet MAC Address #56Ethernet MAC Address #5 assigned to the AM572x IDK EVM. This is the last of a block of 6 contiguous addresses available for the industrial interface ports.
