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

你好,我们现在遇到一个问题,参照官方的开发板设计,ENET使用的也是KSZ8081,唯一变化的是复位采用的是另外的管脚进行的复位,现在问题是KSZ8081可以LINK UP,但是不能进行数据通信,我们设置RT1176和电脑端同时发送数据,测试KSZ8081的TX和RX,发现TX端没有信号,RX端有信号,请问,我改了复位管脚后,在SDK里面还需要做什么样的改变呢?

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.

Hi @BVJ2Vs 

 

Yes, ENET_QoS connected to both CM7 and CM4.

 

RT1176 has 3 MACs, 2 Gigabit Ethernet controller and 1 10M/100M Ethernet Controller. Please refer to the reference manual.
