AM335x双网口第二个千兆网卡ping不通

Other Parts Discussed in Thread: TPS65910, TPS65217, TMP275, PROFIBUS, AM3352

现在自己做的板子网口部分是参考EVM_SK设计的,AR8031,现在移植了linux3.2.0的网口驱动只有一个正常工作,另一个怎么也ping不通,link,设置ip都没问题,我发现手动启用两个网卡,返回的id都是一样的0x4dd074,见附件,希望有知道解决办法的高手帮忙解答,谢谢啦.

  • 贴下kernel配置 arch/arm/mach-omap2/board-am335xevm.c 整个文件,如果可以给下电路图,我搞过,不难搞。

  • 你用了2个 AR8031, 电路和Starter kit 一样吗?

  • 是一样的,你知道什么原因产生的吗?

  • 我也遇到了和你差不多的问题,不过我是两个EHT都无法PING通,使用的是AR8035,使用RGMII接口和英蓓特 SBC8600B是一样的,但是网络能LINK UP,LINK DOWN,也能从LINUX下看到有TX,RX的数据,但就是PING不通,所有可能的原因都查了好几遍还是无果。说明如下:
    1、使用的接口为RGMII,在10M,100M下都进行过测试,10M下MII信号波型较好,100M就很差了,但是另一个使用RTL8211E的开发板也是这样的波型,应当可以排除由于信号电平不足引起。
    2、开始怀疑时序上问题,因为RGMII使用了时钟的双边延对数据进行取样,RGMII一般也带内部的delay,配置内部延时无效,通过外部将CLK延时无效(能够看到建立时间比更改前要长了,最后测试无效。
    3、AR8035支持三种的debug模式,分别是 Digital Loopback,External cable loopback,Remote PHY Loopback,这三种都是通过配置寄存器方式测试,但是文档上没有提到任何如何获知当前测试结果的说明,第一、二配了后无效,第三有一个寄存器位无法写入。最后无果。
    4、其它还有怀疑MAC地址,芯片的硬件ID等,都无果。

    如果你已经解决,也请告知,谢谢。

  • 你好!

    不知道你们的问题是否已经解决,我的电路板上使用了AM3352 + AR8031芯片,发现网络不通。

    我通过飞线将AM3352连接到之前用过的PHY芯片RTL8211EG上面,网络可以正常通讯。所以推断问题在AR8031上面,我使用的也是RGMII接口,使用ping命令,系统一直提示网络连接未就绪,测试发现网络的差分对上无任何波形,但AR8031已经工作。

  • 有参考TI评估板的原理图和布线吗,TI评估板用的就是AR8031

  • 两个网口连到同一个网络,还是不同网络?

  • 你好,不知道你的问题解决了吗?我也遇到了和你相同的问题,如果解决了,向你请教下,谢谢!

  • 你好,我也遇到一样的问题,只是我是第二个EHT无法ping通,第一个可以,两个EHT都可以Link UP和Link Down。

    不知道你是否已经解决,如果解决请告诉我一下,谢谢!

  • 请问你第一路网口调试起来费劲么,还是一上来就是好的。

    我现在的情况是也是2路网口,不过第一路怎么也ping不同,自协商什么都是成功的,也link up了

    你第一路是怎么弄好的,给点意见

    qq8341248@163.com

  • 怎么发给你呢,大哥,

  •  在哪可以看的到。。

  • 2个网卡默认要工作在不同的网段。

  • 你好,我用了两个AR8031,外边接的是光口,参考了TI的布局布线,引脚复用也配置了,但现在只有一个是可以link up,ping不通,另外一路无法识别。请问除了上边的这些,还有什么需要特殊配置的吗?

  • 你好,我也是遇到和你相同的问题,请问你最后是怎么解决的呢?
