Hello all,
I am having trouble mounting to the NFS server on my host Linux machine.
My configuration is as follows.
I am using Ubuntu 9.10 as host OS
I am working with TI DM6446 evaluation board
I am referencing the SPRUE66B document
My evaluation board ethernet cable is plugged directly into the ethernet
port of my host machine, so i configured the ip statically.
I have done the following steps from:
1.) Installed the target linux software on host.
2.) Installed the DVSDK software on host.
3.) Installed CODEC servers on host.
4.) Copied target file system with permisions to location
/home/chris/workdir/filesys 5.) Edit /etc/exports file to read:
/home/chris/workdir/filesys
*(rw,no_root_squash,no_all_squash,sync) 6.) Start NFS Server:
sudo /etc/init.d/nfs-kernel-server restart
7.) Disable firewall using firestarter application
9.) Open terminal session in minicom
10.) Set following environment variables:
EVM # setenv nfshost 192.168.1.100
EVM # setenv rootpath home/chris/workdir/filesys
Make this /home/chris/workdir/filesys and it should work.
