MCU-PLUS-SDK-AM243X: Is Board ID EEPROM EEPROM (AT24CM01) necessary on AM243x?

Part Number: MCU-PLUS-SDK-AM243X

Hi Champs,

A special thanks for your help in advance!

Customer need to design our own AM243x, but we get a little bit confuse about EEPROM based on Board ID EEPROM EEPROM (AT24CM01). is necessary?

#1. We see that the PN_RT_MII example has the define about HW_BOARD on AT24CM01, as showed the below figure.

If it's necessary for customer develop their board,  How to write the AT24CM01? Or other chip would work okay?

#2. If it is not necessary for customer develop their board, will it have an impact on Profinet communication?

Because I saw that the Board ID EEPROM EEPROM has setup the MAC_Adr. So How to define in S/W? Thanks~

    The EEPROM is not a constraint, as long as you provide a MAC address via software or some other non volatile memory location.

    No it will not have any impact. You can give mac address using following function 

    APP_HW_BOARD_INFO_SMAC_Addr_t APP_HW_BOARD_INFO_getMacInfo(void)

    in mcu_plus_sdk_am243x_08_03_00_18\examples\industrial_comms\profinet_device_demo\appHw\eeprom\appHwBoardInfo.c

    Note: You will need some non volatile memory(flash or eeprom) for few specific requirements in example.
