I am have installed 'ti-processor-sdk-linux-am57xx-evm-09_03_06_05' and following this documentation to run the setup scripts. Once I run the ./setup.sh the required packages are installed and proceeds normally, the NFS setup is also done successfully installed. After that, while setting  up TFTP I am getting the following error.

--------------------------------------------------------------------------------
Do you wish to run tftp setup (Press (Y) to run, (n) to skip) ? y
--------------------------------------------------------------------------------
Which directory do you want to be your tftp root directory?(if this directory does not exist it will be created for you)
[ /tftpboot ] ./tftp
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
This step will set up the tftp server in the ./tftp directory.

Note! This command requires you to have administrator priviliges (sudo access)
on your host.
Press return to continue
ls: cannot access './bin/../board-support/prebuilt-images/*Image-.bin': No such file or directory
cp: missing destination file operand after './tftp'
Try 'cp --help' for more information.
Failed setup, aborting..
