挂载Android NFS文件系统出现:nfs: server 192.168.1.229 not responding, still trying

[kangear]

android NFS如下操作方法: 1.chmod 777 /work/a8/android-4.0.3_r1/rootfs_dir

2、重启服务 $sudo /etc/init.d/portmap restart $sudo /etc/init.d/nfs-kernel-server restart

3.setenv root=/dev/nfs nfsroot=192.168.1.229:/work/a8/android-4.0.3_r1/rootfs_dir ip=192.168.1.230:192.168.1.229:192.168.1.1:255.255.255.0::eth0:off rw console=ttySAC0,115200 init=/linuxrc androidboot.console=ttySAC0 mem=512M androidboot.console=s3c2410_serial0 mem=512M skipcali=y ctp=2

这个用SuperBoot来启动NFS Android4 文件系统也会有这个问题，从启动可以看出Android已经挂载上了，只是在在启动到69.25087后出现了问题，网上搜集资料，很可能是android文件系统中启动配置文件中对开发板ip进行了重置，导致的问题。

这个虽然已经不算是Bootloader的问题了，但是记录下来也是有意义的。

挂载部分NFS文件系统（非根文件系统）也出现了这个BUG，但是不影响使用。原来应该是一样的原理。

以前一直是没有怎么做android开发，就把嵌入式linux的一些经验拿到Android上来，比如这次的nfs，工作的时间长了，现在认识到在Android中是一个相当鸡肋的功能。Android提供的adb sync一键同步PC上的文件。甩nfs几条街。
