I have set up the EZSDK with default settings.As it says in the "DM816x C6A816x AM389x EZ Software Developers Guide"
If you accepted the defaults during the setup process, you will now have set up your development host and
target to:
1. Boot the Linux kernel from your development host using TFTP. On your development host the Linux
kernel is fetched from /tftpboot by default.
2. Boot the Linux file system from your development host using NFS. On your development host the
Linux target file system is located at ${HOME}/targetfs
3. Minicom is set up to communicate with the target over RS-232. If you want to use a windows host for
connecting to the target instead, see the #Setting_up_Tera_Term section.
Note! To boot the board from NFS, you may need to change the boot switch settings on your EVM. Please
refer the UBoot user guide in the psp/docs folder for more information on the switch settings.
But I can't find any point on the switch settings in the User Guide.However we just set that SW3---BTM[4:0] ==> 10111 ,SW4---NAND[on],SPI[off].
Because of no router,we use the static ip as ipaddr.
Here is the environment variables:

With these settings ,my groupmate has successfully booted the borad with his computer(host).
Here is his output on the minicom:
