Now set up your terminal program to take input from a file. If you are using minicom, type <ctl-

The next step is to read the u-boot environment file you just modified. If you are using
minicom, type <ctl-A> and Z to bring up the Command Summary. Type “Y” for “Paste file.”

This should bring up the “Select file for upload” window pointing to your home directory. From
here, use the up and down arrow keys to scroll down and select the “u-boot-env-dm810x-
rdk.txt” file you modified and then copied in step (3e). Press the space bar to tag the file.
Then, use the left and right arrow keys to select “Okay”. Press <return>.

say “Saving Environment to NAND…”
