关于dm8168 的网络物理地址ethaddr(MAC)的问题



您好:

      dm8168  evm板u-boot启动时打印如下内容:

Net: <ethaddr> not set. Reading from E-fuse
Detected MACID:84:7e:40:xx:xx:xx
Ethernet PHY: GENERIC @ 0x01
DaVinci EMAC

     查看手册发现8168内部有寄存器是存放网卡地址的,那么,问题就来了:

      1、这个84:7e:40:xx:xx:xx是ti出厂前固化好可以使用的物理地址吗?

      2、如果不是,是否可以写驱动配置相应寄存器,从而设置物理ethaddr而不借助外部EEPROM?

谢谢!

祝:工作愉快!
