AM3358: Doesn't each AM3358 SOC have a unique Ethernet MAC address?

Part Number: AM3358

Hi ,

We encountered a strange phenomenon.The repairing personnel reported to me that after replacing 1 piece of AM3358BZCZ100 into our product board, The ethernet MAC address is unchanged.

(You can run the ifconfig command to display that the MAC address ). For this reason we have replaced the another am3358bCZ100 again. The MAC address did not change.Can you explain this phenomenon?

  • Hi,

    Each AM335x does have a unique MAC address. Since you are running I will assume that you are using Linux. U-boot passes the MAC Address to the kernel. Which version of the TI SDK are you using?

  • Hi SHuyler,

    Thanks,  We changed a raw eMMC, and programming it again. The MAC address has changed to right value.  I suspect that the U-boot in EMMC retains the previous MAC address, although I would argue that, even if it did, U-boot should read the new MAC address from the new CPU.I don't know exactly why.
