C6678 SGMII口问题

感谢Andy的回答

    按照你给的帖子的内容，我用两种方法都测试了，但是SGMII0口还是没有通。之前通过SGMII能够跑通HUA和Client程序，能通过电脑打开192.168.2.100的界面。

------------------------------------------------------------------------------------------------------------

方法1. 用GE程序中的GE_TEST_DSP0_TO_DSP1程序对SGMII1和SGMII0口分别测试。

            a.首先，PC机与板子的网口SGMII1口相连，配置如下：

                GE_Test_Data_Path test_data_path= GE_TEST_DSP0_TO_DSP1;

                Ethernet_Mode ethernet_mode = ETHERNET_AUTO_NEGOTIAT_MASTER;

                GE_Port_Connection port_connect[GE_NUM_ETHERNET_PORT]=
                {
                  GE_PORT_CABLE_CONNECT, //SGMII port 0 
                  GE_PORT_NO_CONNECT //SGMII port 1
                 };

                 然后下载运行程序，显示结果为：              

[C66xx_0] Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz
Initialize PASS clock = 100.00MHzx21/2 = 1050.000MHz
Initialize DDR speed = 66.67MHzx20/1 = 1333.333MTS

                         用wireshark抓包，并没有相关的包，感觉数据没有发送出来。

               b.PC网口与SGMII0口相连，程序配置与上面相反。结果：

[C66xx_0] Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz
Initialize PASS clock = 100.00MHzx21/2 = 1050.000MHz
Initialize DDR speed = 66.67MHzx20/1 = 1333.333MTS
Enable Exception handling...
GE auto negotiation (master) two DSPs test (DSP0 -> DSP1)...

                 感觉更不对。

方法2. 改platform.c程序，PLATFORM_EMAC_PORT_MODE_AMC替换为PLATFORM_EMAC_PORT_MODE_PHY

             参考链接http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/p/150203/547893.aspx#547893

             但是，结果还是不能跑通SGMII0口。

板子的88E1111的电压和时钟都没有问题，SGMII两口与PC相连都可以自协商成100M；

求帮忙分析分析，看问题出哪了。
