NFS服务设置正确了吗?可以在PC上测试一下!

【 在 ccliu 的大作中提到: 】 : NFS服务设置正确了吗?可以在PC上测试一下! 应该没问题，测过了 貌似还是板子那边的问题，emac识别要是不正常的话大概就连不上了

nfs应该没问题啊，好像是网卡初始化和启动网卡设备出现的问题（网卡驱动是直接编译进内核的） 网上看到说：“如果驱动程序已经在内核中了，那么多网卡的设置已经有了。但是， 缺省的情况是自动检测一块网卡，这样可以防止在启动时不正常的挂起” 但是看启动信息只有两个网卡都检测到了，并且正确选择了从eth0启动才能正常加载文件系统，而打印出按道理上说应该正确的“EMAC1 can't find phy”的时候就根本启动不了网卡设备

搞不懂为啥eth1也跟着凑热闹,maybe make menuconfig可以把它去掉?

把之前出现的问题也说下,之前内核移植出了好多问题,最后都归结到应该是U-BOOT在给内核传参数的时候出了错,因此往内核代码中将有些参数写成固定值了,写死的地方有(串口的波特率,以太网的MAC地址,内存的大小)现在在想是否因为之前的问题导致内核出现了什么异常,总之太诡异了,郁闷了

那你就重新编译uboot,不设bootargs这个参数,让linux内核用固定的参数!
