335x rgmii2外接phy芯片88e1510调试100M通信 ，ping命令时，请问为什么rgmii2的tx[0-3]没有输出?

可以在U-Boot下直接配置CPSW工作在rgmii方式下。
现在MDIO访问是成功的么？

你好，感谢回复。mdio访问是成功的。 U-Boot下直接配置CPSW工作在rgmii方式下，这个怎么配置呢？要参考数据手册那一部分？或者ti的sdk里面哪里有相关的源码参考，谢谢！

请参考boardtiam335xboard.c中的board_eth_init()函数，在函数里面进行修改。

你好，我换了一个官方的sdk，现在在uboot下可以ping通了，但在内核下ping不通，具体如下：
U-Boot# setenv ipaddr 192.172.1.8;setenv serverip 192.172.1.85;setenv gatewayip 192.172.1.1;ping 192.172.1.85;
link up on port 0, speed 100, full duplex
link up on port 1, speed 100, full duplex
Using cpsw device
host 192.172.1.85 is alive
可以看出rgmii2是绑定在port 1 上的，可以这样理解么？？（因为用port 0 一直ping不通） 

2. 以下是内核启动网卡相关的信息：

可以看出找到了两个mac地址，那我应该用那一个呢？？

请问如何处理？？我觉得应该是用eth1去ping才能ping通，是这样么？？  谢谢

U-boot下只有一个网口能PING通，对应kernel下这个网口能ping通么？

修改内核
static struct cpsw_slave_data am33xx_cpsw_slaves[] = [
[
.slave_reg_ofs = 0x200,
.sliver_reg_ofs = 0xd80,
.phy_id = "0:01",
.dual_emac_reserved_vlan = CPSW_PORT_VLAN_SLAVE_0,
],
[
.slave_reg_ofs = 0x300,
.sliver_reg_ofs = 0xdc0,
.phy_id = "0:00",
.dual_emac_reserved_vlan = CPSW_PORT_VLAN_SLAVE_1,
],
];

执行以下命令搞定
~ # ifconfig eth1 192.172.1.111 netmask 255.255.255.0 up
~ # ping -I eth1 192.172.1.85

zhiwen lin，您好！
   我看你这个问题在uboot下面调试通过了，我想问下你是怎么解决的，才能让rgmii2口的txd正常的输出信号，我现在使用的am3352也遇到过同样的问题了，配置成rgmii2之后，只有txclk有时钟，但是ping包无法ping通，查看txd的引脚，没有数据发出来。我现在也在uboot调试双网卡阶段。
   你所说的cpsw_data数据结构中的slaves指的是网卡的数量，这个参数正确么？如果我要支持两个网卡，是不是要吧这个参数配置为2，另外host_port_num这个参数是什么意思呢？我没太看明白。谢谢！
