Hi,

I am working on a project that the RT1064 ENET connect to a Ethernet Switch (IP175D)through EMII mode and MAC to MAC  connection. The connection is below, I have modified the phy library and test the "dhcp_start()" function to send the enet command to network. 

I got the waveform form the wires. It seemd the RT1064 can not to decode the received signal from the IP175D.

How can I fix these issue?

Hi @chhsu0229 

Please check below comments

1. it is normal MAC without any RMII feature for RT1064, please check if this Switch(IP175D) support ReverseMII or not.

2. Please check the spec of IP175D to double confirm the hardware connection is correct, sometimes it may be reversed at the MAC-2-MAC connection.

3. Please check the send data, Can the Switch get the dhcp discover function?

 

BR.
