Re: 挂载nfs失败。

做两个测试:
① 用 flash/eMMC 启动 imx6ul,通过你上面的命令行挂载 nfs,看是否正常。
② 在别的电脑,用上面的命令行挂载 nfs, 看是否正常。

Re: 挂载nfs失败。

emmc启动板子,运行deiban,安装nfs-common,可以挂载pc上的nfs文件夹。
所以,还是板子上的环境变量设置有问题。
目前bootargs:

setenv bootargs 'console=tty1 console=ttymxc0,115200 root=/dev/nfs nfsroot=192.168.1.104:/home/any/MPU/imx6ul/nfs/debian,proto=tcp rw ip=192.168.1.108:192.168.1.104:127.0.0.1:255.0.0.0::eth0:off init=/linuxrc'

Re: 挂载nfs失败。

内核参数加上 nfsrootdebug=1 可以看到 nfs 挂载过程的日志。另外,试试 nfsroot 加上 v3 参数(nfsroot=192.168.1.104:/home/any/MPU/imx6ul/nfs/debian,v3),这么新的内核版本默认应该是 v4,我这使用 v4 起不来,也没去细究原因。

加上v3确实有用。感谢。

好象是挂载了,但是没找到/linuxrc文件?

-------------------------------------------

网上搜到的解决办法:

错误现象:busybox做文件系统时,初学者会遇到挂载文件系统错误,Requested init /linuxrc failed (error -2).
解决办法:将busybox编译改为静态编译时,挂载文件系统顺利,这是因为shared方式时,busybox编出来的文件系统不带动态库,或者开发者没有将动态库复制完整,供参考,少走弯路
[ ] Build BusyBox as a static binary (no shared libs) 

但是,我这里是用debootstrip制作的根文件系统啊。

-------------------------------------------------------------------

把bootargs里的init=/linuxrc去掉,可以挂载nfs了。
之前挂载不成功,可能是ip网关设置不正确,我这里是多层路由器,网关不是192.168.1.1。

Re: 挂载nfs失败。

现在又卡debian启动了。
其实一开始挂载成功了,只不过登陆帐号我输入root,总是提示我不正确,连密码都没让我输入。
然后我又去pc上chroot,passwd root冲设了下密码,结果再将这个文件夹复制到nfs目录(用的cp -arf),结果启动debian就一直卡这里。

将nfs目录删除,重新复制debian目录过来,然后chmod、chown给予目录权限,可以登陆了。

Re: 挂载nfs失败。

在nfs启动后,将打包好的跟文件系统解压到/dev/mmcblk1p2上,然后从emmc启动。bootcmd和bootargs按默认的来,结果仍是报错。感觉好像还是和Init=/linuxrc有关,但是不知道环境变量里是那里设置了。

按说,我板子上emmc是ext4分区,PC上建立debian跟文件系统的ubuntu也是ext4格式。

----------------------------

是解压的问题,解压出来竟然还多了个外层目录,将所有文件移出来就好了。

目前有个碍眼的地方:

EXT4-fs (mmcblk1p2): mounting ext3 file system using the ext4 subsystem

-------------------------------------------
bootargs里加上rootfstype=ext4就可以了。
注意uboot默认命令的话,mmcargs会重写bootargs,所以在mmcargs里加上也可以。

Re: 挂载nfs失败。

debian11没有ifconfig和udhcpc,但是有ip命令,执行ip addr后自动分配地址。
