TI中文支持网各位好：
我们使用的AM3352的CPU，现在在我司的板上程序运行起来后，网卡状态都是正常的，可以收到广播包，但是别的机器ping不通板，板也ping不通别的机器，感觉就是发不出包，请各位帮忙分析看看，先谢了。
开发包：ti-processor-sdk-linux-am335x-evm-01.00.00.03-Linux-x86-Install.bin
网络芯片：DP83848J
驱动：cpsw
文件系统：initramfs，使用arago-base-tisdk-image-am335x-evm.tar.gz解压过后编译到内核
启动方式：netboot
网卡模式：MII
PHYID:7
dtb：见附件
启动后，网卡的信息如下(MAC地址是我在u-boot里面用代码设置的）:
eth0 Link encap:Ethernet HWaddr 00:84:00:16:05:05 inet addr:192.168.10.106 Bcast:192.168.10.255 Mask:255.255.255.0

ethtool查看eth0信息如下：

从另外一台机器（192.168.10.12）ping开发板（192.168.10.106），在192.168.10.106上抓包信息如下：

请问有在U-boot下试过网络基本功能么？MDIO访问PHY芯片都是正常的?
Mark Liao：

u-boot下网卡收发是正常的，我是从网络启动的，u-boot从网口加载kernel然后启动系统。
u-boot下mido和phy寄存器如下：
ctrl=0x410000ff alive=0xff000ff link=0xfc000e6 linkintraw=0x0 userintmaskset=0x0 userintraw=0x1 linkintmasked=0x0 userintmaskset=0x0 userintmaskclr=0x0 user[0].access=0x22074615 user[0].physel=0x0 nBMCR =0x3100 nMII_BMSR =0x786d nMII_PHYSID1 =0x2000 nMII_PHYSID2 =0x5c90 nMII_ADVERTISE =0x1e1 nMII_LPA =0xc9e1 nMII_EXPANSION =0xd nMII_ANPTR =0x2801 nMII_PHY_STS =0x4615 nMII_PHYADDR =0x8027
Kernel下mdio和phy寄存器如下：

是否和电源管理有关？我们的单板是固定电压，没有电源管理芯片。
Jian Zhou：
回复 Mark Liao:
如果U-boot下网络工作正常，硬件出问题的可能性不大。
kernel下有量那些信号线有数据输出和输入么？
另外检查下kernel下是否关掉了防火墙。
Mark Liao：
回复 Jian Zhou:
用示波器测量TX数据线没有信号输出，u-boot的TX数据线有信号，这个和防火墙有关？
Mark Liao：
回复 Mark Liao:
防火墙没有编译进内核，但是相同的内核，可以在TI官方的Demo板跑起来，而且网口收发正常。
Mark Liao：
回复 Mark Liao:
内核开了防火墙，其结果一样，user[0].access=0x208701e1这个寄存器的值在u-boot和kernel下不一样，看手册貌似和电源管理有关
Jian Zhou：
回复 Mark Liao:
如果TX信号输出都没有，建议检查下kernel下的pinmux设置。
Mark Liao：
回复 Jian Zhou:
完整的dts文件在1楼的附件中，pinmux设置如下，网卡为MII模式 gmii_sel寄存器已设置为0，这个引脚设置和u-boot一样，只是我们的没有电源管理，所以sleep的没有设置。另外帮忙检查下dts文件中双网卡设置，我们的单板am3352接DP83848J的PHY芯片(PHYID=7)和和IP175D(PHYID=4)交换芯片。谢了。
