During the initialization stage of Ethernet Firmware, the Ethernet ports areopened, which triggers a PHY state machine in Enet LLD that takes care of configuring the Ethernet PHYs via MDIO. However, this excludes any board level setting, such as taking the PHY out of reset. ...
Pratheesh Gangadhar TK, David Zaucha ABSTRACT As a bridge of the link layer device medium access controller (MAC) and physical medium such as copper cable, the Ethernet physical layer device (PHY) integrates all the physical-layer functions needed to transmit and receive data on standard twisted-...
Hi I am using imx.6 dual lite processor for my custom board. I am trying to bring up the Ethernet interface. The eth PHY is a SMSC8740. I am using
In this mode, the PHY allows 8ms for the MAC to decide if TC-10 sleep mode must be enabled or not. If the MAC decides to allow TC-10, the PHY proceeds to the next step in TC-10 state machine. However, the MAC can decide to abort TC-10 and the PHY returns to Normal mode. ...
The state of the hardware configuration pins is read and latched, the digital and analog circuits are initialized, and the PHY core clock multiplier unit (CMU) is reset. After 5 ms from the deassertion of RESET_N, the management interface registers are accessible and the device can be ...

An Ethernet PHY may receive an indication from a local timing source that a local clock is suitable for propagation to a link partner. In response, a timer in the Ethernet PHY may b
Additionally, I'd like to ask if your suggestion for implementing ExternalPhyManagement involves using my custom-defined PHY status to force the driver to directly connect to the PHY. This means disregarding the or...
