DP83TG720R-Q1: how to check the test mode7?

Part Number:DP83TG720R-Q1Other Parts Discussed in Thread:DP83TG720EVM-MC,

hi :

i have some questions ,Hope to receive an answer.

1:how to check the data received?read the register value through SMI interface or tools on the pc?

    i bought two DP83TG720EVM-MC boards,link up through Rosenberger H-MTD;set the master into test mode7,link the slave to pc by RJ45.i can the leds on slave(D2)and RJ45 are bliking,but no data receive on pc through tools(wireshark);

   would you tell me the other way to check the data(if there is).it is hard to test the pam3 smybol on oscillsoscope,and no tools such as VN5611.

2:there is no EEE ability on DP83TG720R-Q1,right?but the DP83TG720R-Q1 also can into sleep mode by remote control(let the bus quiet),it is not suitable for partial wake up ,right?

linch zhang 说:there is no EEE ability on DP83TG720R-Q1,right?

是的,DP83TG720R-不支持EEE。

linch zhang 说:but the DP83TG720R-Q1 also can into sleep mode by remote control(let the bus quiet),it is not suitable for partial wake up ,right?

是的,可以remote 控制sleep状态, partial wake up部分唤醒是吗?应该是不可以的。

linch zhang 说:1:how to check the data received?read the register value through SMI interface or tools on the pc?

是的,SMI可以用来对其进行寄存器的读写。

但是如果没有SMI,通过strap pin的配置数据也是可以传输的。

linch zhang:

好的,非常感谢,可以用中文Joy

那还还有一个问题就是testmode7是怎么用的,我testmode7设置好之后,用smi去读哪个寄存器来看误码率啊。有没有什么资料可以看,或者告诉我去读哪个寄存器,我大致看了下,貌似没有寄存器是对应testmode7用的嘛

,

Kailyn Chen:

抱歉,我没有找到关于test mode7的更多介绍,这篇关于 DP838xx兼容性测试的应用手册中也没有详细介绍test mode7

或者建议您在英文E2E论坛上咨询下产品工程师呢:
