Thanks William, but the line in red is just commented out to indicate it is
not part of the working file. I did not work without the hash.
I have followed these instructions
http://elinux.org/Beagleboard:U-boot_partitioning_layout_2.0#nfs_support and
there is no mention of any netargs..
Apologies for my ignorance, but I am brand new to all this and having a
hard time following, would you please clarify how to achieve what you
mentioned.
the display is now not balnking after adding the optargs to uEnv.txt in the
fat boot partition but for learning sake, I would like to know how to
achieve this in the /boot/uEnv.txt
Thanks for the help.
Rob
