我用的是官方的EVM板，我的SW5的设置是off ,也就是拨码开关都设置为靠近PCIE插座。在这种设置下，当我插了PCIE网卡（x1），上电串口竟然无反应，此PCIE网卡我已经在PC机上测试过了，可以使用。以下是我不插PCIE网卡的时候串口打印信息。

你好，
请参考：http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_PCI_Express_Root_Complex_Driver_User_Guide 中的Taking care of PERSTn部分。 |

cmh8 发表于 2018-6-21 00:30 目前的情况是我的SW5的设置是off ,也就是拨码开关都设置为靠近PCIE插座。在这种设置下，当我插了PCIE网卡（x1），上电串口无反应，我的系统起不来，按照E2E上老外给的说法，当我连接PCIE网卡设备的时候，SW5应该就是这样设置的。 http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/106374.aspx OFF is towards the PCIe slot, that is farther to R195. The switch bank has written "ON" (small font) on it on the opposite side. 我的PCIE网卡在PC机上测试过的，可以用。 |

binro 发表于 2018-6-21 00:45 你好， 由于DM8168不支持PCIE设备的热插拔，而设置SW5为OFF的目的在于，保证EP设备优先于RC设备启动，使用EP设备的复位信号通过SLOT的A11来复位RC设备。 当你的网卡插PCIE slot的时候，你看一下，是否是A11脚的电平不正常，这样导致了DM8168一直处于复位状态，无法正常启动。 同时查一下，你的PCIE X1网卡是否用到了B10 3.3VAUX这个pin脚供电，在EVM上，这个脚是悬空的。 |

cmh8 发表于 2018-6-21 01:04 我给B11飞了一个3.3V供电，现在PCIE网卡能识别到了，也驱动起来了，可以给ethX来配置ip，但是ping不通，暂时不清楚原因，驱动我用的是官方下载的驱动。明天打算用官方推荐的BCM5751测试一下。 同时问一个问题，板子上的PCIE2X是不是可以扩两路千兆以太网？ |

binro 发表于 2018-6-21 01:10 不行，只能支持一路PCIE2X或者一路PCIE1X。 |

好的，谢谢louis，我买的BCM5751明天会到公司进行测试，到时候通了我会再回复一下的。 |

binro 发表于 2018-6-21 01:55 从log信息来看，PCIe 网卡BCM5751已经找到，并且网络link已经建立。PCIe应该没有什么问题，问题应该在网络驱动和使用方面。 网络连接使用dhcp还是静态IP？从log信息看dhcp应该不能工作。你的网络是怎么配置的？ /bin/sh: udhcpc: not found 01:00.0 Class 0200: Device 14e4:1677 (rev 11) …….. tg3 0000:01:00.0: eth0: Link is up at 100 Mbps, full duplex tg3 0000:01:00.0: eth0: Flow control is on for TX and on for RX ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready |

60user112 发表于 2018-6-21 02:21 我工作的时候是设置的静态的IP。 dhcp其实是可以使用的，只是我把udhcpc这个命令去掉了，所以log里面有这么一句/bin/sh: udhcpc: not found。 我也还疑过是驱动的问题，所以我另外尝试了RTL8111C和INTEL82574这两款PCIE 网卡，情况基本是一样的,我觉得不大可能是三家公司的驱动同时有问题。 TI的原理图上，wake脚没有接，我不清楚这个会不会带来大的影响？我看了几个其他平台的PCIE包括笔记本的，都是接了的。 |

60user112 发表于 2018-6-21 02:21 包括SW5的设置，无论是on还是off都尝试过了。 包括这一段 Controlling PERSTn Using I2C Writes Note that this description assumes the above mentioned EVM modification is already done. As mentioned earlier, the PERSTn line on the A11 pin of PCIe slot on the EVM can be toggled by controlling I2C0 writes to IOEXPANDER port 14. This corresponds to performing i2c writes to address 0x20 bit 12. • Setting this bit to 1 makes PERSTn pin high (EP reset de-asserted). • Setting this bit to 0 means PERSTn pin low (reset asserted) and EP will remain in reset. As an example, following commands at U-Boot prompt will toggle reset to EP during boot: TI8168_EVM# i2c mw 0x20 ff ef <--- Set bit 12 to 0 to assert PERSTn (default is 1, de-asserted) TI8168_EVM# i2c mw 0x20 ff ff <--- Set bit 12 to 1 to de-assert PERSTn and get EP out of reset The above sequence can be set as part of U-Boot's bootcmd as shown below to ensure it is executed on every reset and before booting the kernel (assuming kernel is flashed in NAND @0x280000 offset): TI8168_EVM# setenv bootcmd 'i2c mw 0x20 ff ef; i2c mw 0x20 ff ff; nand read.i 81000000 280000 500000; bootm 81000000' TI8168_EVM# saveenv This sequence can also be added to Kernel board file to perform similar i2c writes at boot up. 能尝试的都尝试了。 Dong Yang 谢谢你对这个帖子的关注。 不知道TI能否在DM8168平台上对 TI81XX PCI Express Root Complex Driver User Guide 这篇手册上针对BCM5751的例子再做一次测试，是否能够在寻找网网卡设备的情况下，进一步ping通， |

Louis你好，我有进一步测试，我像eth0发送原始包，发现可以接受到数据，RX bytes:689363584 (657.4 MiB)。 root@luhao:~# ifconfig eth0 Link encap:Ethernet HWaddr 00:10:18:24:40:0C inet addr:193.168.252.10 Bcast:193.168.252.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:538053 errors:0 dropped:538017 overruns:0 frame:1 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:689363584 (657.4 MiB) TX bytes:0 (0.0 B) Interrupt:48 但就是不支持协议栈收发。 |

binro 发表于 2018-6-21 04:03 从你的打印信息上看，RTL8111C并没有在PCI Scan中扫描到，你用的是TI的EVM么？请在PCI SCAN的时候把LTSSM寄存器打印一下。 |
