We are using tja1100 ETH PHY for BroadReach ETH communication,
Connection is as follows:
Microcontroller is connected to TJA1100 via RMII.
PHY is controlled by uc using MDIO, MDC PINs.
The following configuration are made for PHY:
Config0: LOW (Configured as Slave)
Config1: LOW (Managed operation)
So, RMII mode (25MHz)
and uc is configured with all required port pin settings.
Problem: Could not establish connection with PHY through RMII. so PHY ID also could not be read.
Whether MDC clock will affect communication with PHY?
