Recently,I run the example of "lwip_mpc5748g" on devkit board of mpc5748g.The default MAC in the app is"0x10,0x11,0x12,0x00,0x00,0x00",default IP is"" . So,I add MAC  address manually into PC ARP cache  with. (arp -s 10-11-12-00-00-00).But,the devkit board still not reply to me when I ping the address.I don not know what is wrong.What should I do? I really need your help.Thank you!
