TI中文支持网求助TI的大神们，
am335x +DP83848双网卡MII模式如何配置（uboot、内核）？我现在用的是SDK7.
因为以前没有网络基础，TI有没有比较简单的手册一步步介绍如何配置？
uboot中对应网络的配置这些值该怎么设置呀？
static struct cpsw_slave_data cpsw_slaves[] = {
{
.slave_reg_ofs = 0x208,
.sliver_reg_ofs = 0xd80,
.phy_addr = 0,
},
{
.slave_reg_ofs = 0x308,
.sliver_reg_ofs = 0xdc0,
.phy_addr = 7,
},
};
static struct cpsw_platform_data cpsw_data = {
.mdio_base = CPSW_MDIO_BASE,
.cpsw_base = CPSW_BASE,
.mdio_div = 0xff,
.channels = 8,
.cpdma_reg_ofs = 0x800,
.slaves = 2,
.slave_data = cpsw_slaves,
.ale_reg_ofs = 0xd00,
.ale_entries = 1024,
.host_port_reg_ofs = 0x108,
.hw_stats_reg_ofs = 0x900,
.bd_ram_ofs = 0x2000,
.mac_control = (1 << 5),
.control = cpsw_control,
.host_port_num = 0,
.version = CPSW_CTRL_VERSION_2,
};

内核中只配置了设备树， 其他还需做什么？

目前的状态是系统中只能显示一个eth0，但是无法获得IP，127.0.0.1 可以ping通

目前的情况是网口1可在Linux系统中看到，网线插上后灯亮（差不多1S闪一次），网口2在系统中看不到，灯也不亮。ping 回环地址能ping通。

这种双网卡的问题，建议先在U-boot下把每个网口都调试一下，然后参考SK板的device tree进行配置。
