Hello,
I can't read the registers of dp83tc811r-q1 through SMI (MDIO/MDC), we set the phy address as 0x0000 and read the 0x0002 register, below is the waveforms of MDIO and MDC. However, I can't get the register data.
I know the MDIO data is locked on the rising edge of MDC, there are some problems of the MDC and MDIO. But customer uses the same procedure and it works for dp83822. Are there any difference of SMI between dp83tc811r-q1 and dp83822? Is this the root cause for register reading issue?
I also checked the power rail and phy adrress setting, i don't see any problem.
Thanks
dongbao
