Hi Alan:
Thank you for your kindly reply.
Last night, after send out the help mail, I have built busybox and try
to run busybox instead of android during boot.
the testing result is:
if I using following nfsroot:
nfsroot=10.67.174.128:/opt/nfsroot
busybox can run normally which seems the nfs works well.
but if I add 'v3,tcp' to the nfsroot like this:
nfsroot=10.67.174.128:/opt/nfsroot,v3,tcp
I got "kernel panic"!!
Following is my board setting and log:
