DP83TC811R-Q1: DP83TC811R-Q1驱动调试问题

Part Number:DP83TC811R-Q1

下述日志是我配置dts以后 驱动输出的日志。

 请问当前状态是否是正常状态?如果有问题是否能从下述日志获取出问题的原因?

谢谢!

Kailyn Chen:

您好,您的这个问题我这边需要进一步去确认一下。

给您带来不便非常抱歉。

,

Kailyn Chen:

您好,看了下这个日志,应该是link 有问题,register 0x0001 = x61,如果link没问题的话正确的值应该为0x0065。

,

pengge yin:

谢谢! 

能判断出事硬件影响还是软件配置导致的问题?

,

feng liang:

有哪些原因导致link有问题?

,

Kailyn Chen:

您好,单纯通过这个日志是不能判断是硬件问题还是软件配置问题。

或者您可以将您的配置或电路图附上以便分析,cable是否有链接? 是否和link partner有连接? 

,

pengge yin:

硬件原理图:

软件侧,我们只修改了dts中的phy_id,用于适配网卡

,

Kailyn Chen:

好的,我这边再帮您看下。

,

Kailyn Chen:

您好,R和C的值建议是按照datasheet中推荐的值。

另外,上述两个问题中,cable是否有和link partner连接?cable没问题吧?
