DP83TC811R-Q1: Problems with BScan on DP83TC811R-Q1

Hello Falk,

How are RESET, EN and WAKE set high. Is there a possibility for any of these going low after startup?

Can you elaborate more on what two registers you are writing to, in which order? What method are you using? I assume you are trying to access the extended register set.

Thanks,

Vibhu

Hello Vibhu,

I measured all signals and all signals are high. I also tried two ways. First WAKE, ENABLE RESET HIGH before Power up. Second WAKE and ENEABLE HIGH RESET LOW before Power up and after Power up RESET HIGH.

The first DR Shift is running good look like the Picture



The first IR Shift is failured look like the Picture

I Think this is the similar Problem like this Topic
