2.10.1.2 Board ID EEPROM

The AM275x EVM features an on-board EEPROM (CAT24M01WI-GT3) which stores the board's version and serial number data. The Board ID EEPROM is interfaced with the I2C0 port of the AM275x EVM SoC and is configured to respond to address 0x54. The I2C address of the EEPROM can be modified by driving the A2 and A1 pin HIGH/LOW to select one of the four possible addresses. The memory is preprogrammed with identification information for each board.

The EEPROM feautures write protection for the entire memory. To perform a write operation to the EEPROM, the WP pin must be shorted with jumper J33.
