Hi,

I am going through the @RT1176 I need confirmation on following points

  1. Is MAC is connected to Core M7 and M4 ?
  2. What is the difference in PTP explained in ENET/ENET_1G and ENET_QoS ?
  3. can able to access 3 ethernet interface ( ENET, ENET_1G, ENET_QoS ) simultaneously ?
  4. In RMII mode PTP will work or not in the manual it is specifically mentioned MII and RGMII ?

 

Thanks in advance

Hi 

For Q1, please refer to the RT1170 Bus Diagram .  1G Ethernet and 10/100M Ethernet connect to M7 and M4 through XB_PER and XB_LPSR.
