Hi,

 

I built the images using 'bitbake core-image-minimal' and able to boot the EVM using SD Card. Now I am trying to boot the device using NFS.

But during the kernel boot, I was getting following errors:

 

*************************************************************************************************************

*************************************************************************************************************

 

The host PC is configured properly for NFS Server.

 

And the weird thing was, on login prompt when I entered username 'root', it was asking for the password. I am not able to understand why this is happening?

 

Please help me to resolve this issue.

 

Thanks,

Dhaval
