NFS 挂载错误，NFS：未知参数'ip'

Question

我试图按照bootlin的文档进行nfs挂载。我将参数设置如下:

setenv bootargs 'console=ttyS0,115200 root=/dev/nfs rw
nfsroot=192.168.0.1:/nfs,nfsvers=3,
ip=192.168.0.100:::::usb0 g_ether.dev_addr=f8:dc:7a:00:00:02
g_ether.host_addr=f8:dc:7a:00:00:01'
setenv bootcmd 'mmc dev 0; devnum=${mmcdev}; setenv devtype mmc;
mmc rescan; run loadimage; run findfdt; run mmcloados'
saveenv

它没有工作，我得到以下;

[    8.007915] nfs: Unknown parameter 'ip'
[   18.407811] nfs: Unknown parameter 'ip'
[   38.887802] nfs: Unknown parameter 'ip'
[   68.967793] nfs: Unknown parameter 'ip'
[   99.047785] nfs: Unknown parameter 'ip'
[   99.051674] VFS: Unable to mount root fs via NFS.

有什么建议，我应该看看修复它?

正在读取ip作为nfsroot的参数:

setenv bootargs 'console=ttyS0,115200 root=/dev/nfs rw
nfsroot=192.168.0.1:/nfs,nfsvers=3,

----------------------------------
ip=192.168.0.100:::::usb0 g_ether.dev_addr=f8:dc:7a:00:00:02
g_ether.host_addr=f8:dc:7a:00:00:01'

ip应该是一个单独的选项:

setenv bootargs 'console=ttyS0,115200 root=/dev/nfs rw ip=192.168.0.100:::::usb0 g_ether.dev_addr=f8:dc:7a:00:00:02
g_ether.host_addr=f8:dc:7a:00:00:01 nfsroot=192.168.0.1:/nfs,v3'
