大家好！
最近做了块6678的板子，PHY部分是按照EVM设计的，基本一模一样，唯一不一样的是88E1111的核电压由EVM上的1.2V改成1.0V。
经过测试，电压1.0V和2.5V都正确。
PHY_RST#也是已经拉高3V3（和EVM一致）。
88E1111的XTAL晶振用示波器测量也是有电压的（看不见频率，EVM也是这样，可能是因为示波器的表笔接触后，负载电容变化的原因）
下面是实验结果：
1>使用MCSDK中helloworld_evm6678l。自协商失败。结果如下图1：
为什么自协商会失败呢？
2>在本论坛：www.deyisupport.com/…/47664.aspx
下载测试了GE这个例子GE_Test_Data_Path test_data_path= GE_TEST_SERDES_LOOPBACK; 这个应该是通过了，打印信息如下：

miker wang：
你好，
1、EVM中的RESET并不是像你说的上拉，而是下拉到地的。这样上电后，只需要用FPGA拉高该引脚就能使88E1111产生复位，只有复位后，它才可以正常进行自协商。按照你的描述，RESET脚从上电就一直被拉高，所以如果你不通过FPGA把它先拉低再拉高是不能使芯片进行复位的，就算插上网线，也不会进行自协商，无法建立物理连接。这可能是你的问题所在。
2、Loopback不会经过phy，扩展到最外层也只能进行SERDES的回环，信号始终在DSP芯片内部。所以这个与phy芯片的工作是否正常没有任何关系。
,
heqiang yang：
您好！
谢谢您的回复，
1、我刚才没说清楚，PHY_RST在上电是是低电平，我是在DSP reset拉高以后才把PHY_RST拉高的，所以PHY应该是复位了。
2、所以我猜想应该不是PHY的问题，而像是DSP那个配置不对。
求指点！！！

Kevin Cai：
Hi, 您好
您的测试说明Serdes loopback测试是正常的, 您可以修改测试代码如下:
GE_Test_Data_Path test_data_path= GE_TEST_DSP0_TO_DSP1;
Ethernet_Mode ethernet_mode = ETHERNET_AUTO_NEGOTIAT_SLAVE;
GE_Port_Connection port_connect[2]={
GE_PORT_CABLE_CONNECT, //SGMII port 0
GE_PORT_CABLE_CONNECT //SGMII port 1};
在DSP核0运行,看DSP能否收发包, 如果不能,单步跟踪一下是到哪一步出错
谢谢!
,
heqiang yang：
您好！
首先对您的回复表示真诚的感谢！辛苦了
我把代码修改成这样了，SGM0，我没有用，如红色
GE_Test_Data_Path test_data_path= GE_TEST_DSP0_TO_DSP1;
Ethernet_Mode ethernet_mode = ETHERNET_AUTO_NEGOTIAT_SLAVE;
GE_Port_Connection port_connect[2]={
GE_PORT_NO_CONNECT, //SGMII port 0
GE_PORT_CABLE_CONNECT //SGMII port 1};
然后把网线插入DSP板子的网口以及PC机的网口。
load GE.out文件，运行结果如下，麻烦您给看下。谢谢

Kevin Cai：
Hi, 您好！
这个测试也是有自协商错误，您的PC机与EVM板连接测试的时候，(自协商)是正常的吗？ 如果正常，说明PC端的设置是对的
谢谢！
,
heqiang yang：
您好！
DSP和PHY的自协商和PC机端的设置有关系吗？需要怎么设置？

您好！
我的板子每次都是在这个地方timeout！ 还是请专家们给分析下原因，非常感谢！我们也一直在努力。
GE_2DSP_Test.c里面
/*wait all packets have been send out successfully*/ while((Get_TX_Good_Frames()-uiTxGoodFrames)<uiTotalNumPackets) { asm(" NOP 5");#if 1 //for debug if(TSC_count_cycle_from(uiCycles)>0x3FFFFFFF) //timeout { puts("waiting for transfer complete timeout!"); print_GE_status_error(); //for debug while(1); //trap }#endif }

Kevin Cai：
Hi, 您好！
您此前用EVM板测试，数据包是发送出去了的； 用您的板子测试的时候，数据包没有发送出去，所以您看到代码停留在这个循环里
没有发送出去的原因是外侧网络存在问题
1. 您可以检查一下您硬件设计使用的是SGMII0还是SGMII1
2. 自协商错误也会出现这种错误，您可以把代码修改为Ethernet_Mode ethernet_mode = ETHERNET_1000M_FULLDUPLEX ，看非自协商是否能通过
谢谢！
,
heqiang yang：
Kevin Cai ,您好!
谢谢您的回复！
1、我用的是SGM1图纸和EVM是一模一样的，只有88E1111的内核电压由1.2V修改为1V了，昨天我也实验了，现在的问题和这个电压没关系。
2. 修改Ethernet_Mode ethernet_mode = ETHERNET_1000M_FULLDUPLEX 后，自协商也是过不去的。无法link up.
请问， 1，link up是DSP读自己的status_reg，这个指的是dsp和phy，应该和网口没关系吧？
2，为什么我分别测试了EVM和自己的板子，MDIO和MDC，这两根线都一直是高电平呢？没发现数据DSP和PHY的数据通信呀？

Kevin Cai：
Hi, 您好！
1. 有关系，这是外侧传递进来的状态
谢谢！
,
Kevin Cai：
Hi, 您好！
您的SGMII1 的serdes输入时钟是多少，跟EVM板一样吗？
谢谢！
,
heqiang yang：
Kevin Cai 您好！
时钟是312.5M和EVM也是一样的，
应该是没有关系的，因为我拿EVM做实验的时候，没有连接网线，然后EVM的SGM0 的状态是0x30,对应的link up是0，因为sgm0是连接到AMC金手指的，也就是没有PHY，
SGM1在没有连接网线的时候状态寄存器是0x3D,link up是1
,
Kevin Cai：
Hi, 您好！
在您的板子上 SGM1在没有连接网线的时候状态寄存器是0x3D,link up是1吗？
谢谢！

我的板子不是0x3D,link up那个bit是0，

我也遇到跟你一样的问题，6678与88E1111的原理图参考EVM，6678连接两个88E1111,两个网口都LINK UP不成功，
请问你现在解决问题了没有？请多多指导
,
zhang zhangyu：
请问你的问题解决了吗，好像碰到这个问题的很多，能给解答一下吗，多谢！
,
heqiang yang：
zhang zhangyu
您好！
解决了，我那个是因为时钟（CDCE62005提供）没有锁定。
,
zhang zhangyu：
我的CDCE62005倒是提示锁定了，有没有可能时钟质量不好，导致这种问题呢？
,
zhuang jiao：
时钟没有锁定，换了时钟芯片吗？还是只是修改时钟芯片配置？最后怎么解决的呢？
,
zhuang jiao：
您好，我测试那个GE的时候三个loopback都可以正常运行，也就是DSP内部运行正常，问题出在外部的网络，这样是不是可以排除是因为SGMII的时钟问题啊，我们的312.5M时钟可以锁定，但是用示波器测量不是很稳定，测EVM上面也不是很稳定，既然SERDES loopback可以正常运行，是不是就可以认为不是时钟的问题啊？
,
zhuang jiao：
Kevin Cai，您好！
我也遇到也类似的问题，连上网线后可以看到LINK和RX的指示灯均正常（LINK指示灯常亮，RX灯闪烁），测试MAC，SGMII和SERDES的loopback也都正常，并且在自己的程序当中，不对SGMII寄存器做配置，直接读状态寄存器时候link up为1，配置之后就变成0了，请问会是哪一块的问题呢，MAC还是PHY的问题呢？希望尽快恢复，项目比较着急，谢谢！！！

changzheng chen：

你好，我和你的现象是一样的，三个loop都可以正常运行，时钟看上去也都锁上了，但是就是link不上，请问你的问题解决了吗，能告诉我吗？
