I am running a target board with the application called minicom. This program requires the NFS-Server to be running. However, my NFS-server has quit or ended and is no longer running. Restarting it does not help. Here is the best I can get for an error log:

VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "nfs" or unknown-block(2,0): error -6
Please append a correct "root=" boot option; here are the available partitions:
1f00             256 mtdblock0  (driver?)
1f01             128 mtdblock1  (driver?)
1f02            5120 mtdblock2  (driver?)
1f03          256640 mtdblock3  (driver?)

Someone else asks something similar, but he did not get any answers, so I thought I would try again.

minicom is just a serial console application. Your problem looks like you are trying to bring up an embedded board and don't have the boot paramaters set correctly. Can you post the actual, complete commands you are using and more information about the board? I very much doubt this problem is with minicom, and you don't say if you are actually intending to map the device's root filesystem over NFS.

I don't know what's causing this, but it's quite possible that it's been fixed in a later version of one of your programs. However, Fedora 17 is past its End Of Life date and there are no more updates for it for any reason, including security. My recommendation is that you upgrade Fedora to a supported version, meaning either 18 or 19 and then try again. If the upgrade doesn't resolve your issue, come back here and try again.

I am trying to get this working for a class I am taking. I did not do a very good job explaining this problem. My teacher posted something as well:

That explains the problem better. The essential problem is that NFS-Server is stopped or finished so I cannot mount across it (again apologies if I am butchering the subject here). My teacher correctly pointed out that it is not a problem with the minicom; my apologies for not making that more clear.

I will try to migrate to the latest versions of the OS, and see if that helps things. I am running this on a VMWARE workstation installation on a Windows 7 box.

Thanks to everyone for the help!
