AM3352: MAC Address is not same with the mac address in ARP

Hi. Experts.

I am using a custom board with am3352 and SDK7

In U-BOOT, When I tried to send ping from the board to PC, it doesn't work.

So, I checked in Wireshark.

I found that the mac address in uboot and the mac address in Wireshark are not same.

In other words, 

The mac address in U-BOOT is "30:e2:83:c6:1a:dc"

The mac address of source in ARP Packet is "30:e2:03:86:1a:dc"

So, the MAC could not receive the ARP Reply.

The mac address in uboot is got from mac register, I guess.

It seems like the mac address could not be given to ARP driver..

Could you give some help to me..?

Best Regard.
