I followed another thread here on how to make the board boot from tftpboot and use the targetNFS folder as the filesystem here: e2e.ti.com/.../1883525
This is my printenv output:

It stops after that, I did chmod 777 and chown nobody for the targetNFS folder just like the script does for tftpboot. How do I get the board to boot from tftpboot and use the targetNFS as the filesystem?
