AM3357: MAC address storage requirement

Part Number: AM3357


Hello,

Let me confirm about below.

* According to AM335X GP EVM, this EVM has EEPROM which storage MAC address for ethernet.
If user want to use their own MAC address, user need to storage MAC address to external non-volatile memory such as above EEPROM. But I would like you to confirm whether there is any requirement to select this memory.
If you have requirement for memory, could you please share it to me ?

Best Regards,

    Hi,

    TI does not have a recommendation for the memory. Though I would recommend using one like what the EVM uses. The I2C EEPROM that is used on the EVM is only about 32K. If you are asking about a size requirement than I would say it does not have to be large. The data stored is just a couple of bytes I believe.

    The EEPROM serves two purposes, board identification and MAC address storage is another. On most TI devices the U-Boot code will read the MAC addresses from there and pass to the kernel.  

    Best Regards,
