ENET 

The i.MX6 provides a 10/100/1000 MAC core, which supports MII, RMII and RGMII. 
The RGMII signals are available as primary function at the connectors. 
The following table shows the signals used by the RGMII interface.

Note: NVCC_ENET 

 

NVCC_ENET_IN has to be connected externally! 

 
 
The RGMII interface of the i.MX6 works with an I/O voltage of 2.5 V. In order to use the interface, additional signals of the signal 

group ENET are required. The accompanying power supply pin is routed to the connector to operate these signals on the same 

I/O voltage, if RGMII is used. 
 

 

If RGMII is used, NVCC_ENET_IN has to be connected to VCC2V5_RGMII_OUT.  

It is important that all ten signals of the signal group ENET are then also set to 2.5 V. 

 

If RGMII is not required, NVCC_ENET_IN has to be connected to VCC3V3_REF_OUT. 

 
 
By adapting the multiplexing, it is possible to use MII or RMII. 
Details are to be taken from the NXP Reference Manuals (4), (5), and (6).
