I enabled promiscuous mode(PHY device) to read/receive all data irrespective of particular type/address of device, sent from MAC. Can you help me out is there any other tool to view raw Ethernet frame? 0 Kudos Reply 05-13-2016 06:41 AM 7,456 Views mjbcswitzerland Specialist V...
same period as the MDC clock. The MDIO bits are latched on the rising edge of the MDC clock. MDC may be stopped between frames provided no timing requirements are violated.MDC must be active during each valid bit of every frame, including all preamble, instruction, address, data, and at ...

at moment I can not change the PHY ID because I am using the card with an application SW that runs only with address ID = 0x02. I think that the ID = 0x02 is read correctly by DP83848 device but the MDIO interface responds wrong. ...
