Hi,

Why are there three EEPROMs on the J721E EVM, and what are their functions?

    The J721E EVM is comprised different boards assembled together.  A processor module (SOM), and common base board (CPB), and a add-on peripheral board (QSGMII).  Each board has Configuration EEPROM to store EVM design information, revision, manufacturing date, etc.  Each board has its own Board ID/Configuration EEPROM.

    From J721E EVM User Guide:

    The J721E EVM User Guide also includes the format of the EEPROM (Table 4-11)
