网卡无法驱动
本帖最后由 shuimu_1 于 2013-04-09 10:23 编辑开发板：MPC8313ERDB
网口：两个千兆网卡
u-boot下都可以互相ping通，移植完uImage以后其中一个网卡无法ping通，不知道从哪分析问题，所以还请各位帮忙想想问题出现的可能原因。
下面是我在启动kernel时候的打印信息

红字何解？？
祝：身体健康，工作顺利 本帖最后由 shuimu_1 于 2013-04-09 10:45 编辑
没人搭理啊！！！
我再说说我现在的情况吧！只求有人路过
我的理解是：
1、platform总线注册
2、mdio总线注册
3、platform总线上设备注册
4、mdio总线上的驱动添加
5、platform上的mdio设备驱动添加并绑定设备
6、mdio总线设备添加并绑定驱动
7、platform上的gianfar设备驱动添加并绑定设备
8、其他
问题一：我跟踪内核源代码的时候，在完成第三步时候，共注册了三个相关网卡的设备：e0024000.ethernet，e0024520.mdio，e0025000.ethernet
（硬件上两个千兆网公用一个cpu上面的mdio口），所以我想知道这里还需要注册设备：e0025520.mdio吗？注册不上可能是什么原因呢？
问题二：完成第5步的时候，我添加了打印消息如下：
driver_probe_device() - mdio_bus: Matched Device e0024520:04 with Driver Marvell 88E1111
driver_probe_device() - mdio_bus: Matched Device e0024520:05 with Driver Marvell 88E1111
貌似驱动和设备绑定不正确，求解？
来人吧、、、呜呜呜 回复 1# shuimu_1
开发板自带的linux kernel 本来就是好的吧 开发版自带的kernel和开发板不对应，所以移植的时候没有参考板 回复 3# goldenfort
我以前用过8313E的板子， 1000m口，支持 ieee1588功能。
我当时直接拿 板子 上的linux 就可以运行， 不需要移植 我们自己做的板子，多少是有点不一样的，硬件上面有中断口换了，硬件地址也换了，其他倒是没什么差别
