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?
