求助DM8127 IPNC RDK的网络问题

steven Lee1 说：

ipnc rdk版本为3.5

从nand中ubifs启动，进入系统网络不通，必须在相机里ping一下主机ip，然后网络就通畅了，这次ping也是直接成功；从主机ping相机无效，不能通。

uboot args如下两种都试过，不知道是不是参数设置有问题

setenv bootargs 'console=ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=80M vram=4M notifyk.vpssm3_sva=0xBFD00000 ip=192.168.1.168 eth=00.0C.0C.02.39.6F cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk'

setenv bootargs 'console=ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=80M vram=4M notifyk.vpssm3_sva=0xBFD00000 ip=192.168.1.168:192.168.1.37:192.168.1.1:255.255.255.0:::off eth=00.0C.0C.02.39.6F cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk'

uboot、内核用光盘自带的和自己编译的都试过，都是这问题

然后nfs启动不成功，应该也是上述问题导致的，不知道是不是内核的网络驱动有问题，大家指教一下，谢谢

bootargs里ip设为dhcp应该会好了，貌似bootargsi静态IP不传进内核

nfs也是如此，我们也试过很多次，只有dhcp能挂载NFS，使用静态IP始终挂不上

谢谢你的回复

我试了一下，把相机的switch切换到DHCP模式，相机和电脑直连

bootargs参数设置如下：setenv bootargs 'console=ttyO0,115200n8 rootwait=1 rw ubi.mtd=4,2048 rootfstype=ubifs root=ubi0:rootfs init=/init mem=80M vram=4M notifyk.vpssm3_sva=0xBFD00000 ip=dhcp eth=00.0C.0C.02.39.6F cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk'

内核启动的时候打印信息如下：

CPSW phy found : id is : 0x4dd074

上面dhcp自动配置那里会卡上好几分钟，进入系统之后ifconfig如下：

网络当然是不通的，dhcp还没配置到ip，过了几分钟之后会有如下打印信息

net_get_netmask: ioctl SIOCGIFNETMASK: Cannot assign requested address

然后网络才会通，这个情况不知道你们遇到过没？

如果设置为nfs启动模式，设置dhcp，bootargs参数如下：setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs rw mem=80M vram=4M notifyk.vpssm3_sva=0xBFD00000 nfsroot=192.168.1.37:/opt/IPNC_RDK_Release_V3.5/Source/ipnc_rdk/target/filesys,nolock ip=dhcp eth=00.0C.0C.02.39.6F cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk'

会一直卡在下面这一段：

CPSW phy found : id is : 0x4dd074
PHY 0:01 not found

PHY: 0:00 - Link is Up - 1000/Full

不知道是不是因为等待的时间不够长。。。

请帮我分析一下，谢谢

不好意思一开始可能理解错了

ubifs启动bootargs如你一开始设的两种方式，switch选择dhcp要通过路由器，直连应该是无效的，你可以试一下这种

switch用静态ip，启动后默认为192.168.1.168，直连你看一下本地pc网络设置，我们这里是没有问题的

NFS启动貌似bootargs里要设为dhcp，也是要通过路由器

如果用直连的话，才需要设静态ip，但以这种方式不知道为什么总是挂不上nfs

多谢您的回复

那我试试通过路由器设置dhcp模式挂载nfs启动看看

直连静态ip我们这个启动之后网络没连上的问题也不知道是为什么，有时候可以连上有时候不能连上
