just press the arrow down key, it will send some control char which interrupts the scrolling. Other keys might work too, it just won't give you a pager like "More" but it's better than nothing. _________________

You don't have to use the U-Boot prompt, you can do nearly everything from an OS4 Shell using the nvgetvar command (for printenv) and nvsetvar (for setenv).

If you use the serial port and redirect the video to it you can use any facility in the terminal program you are using to record all the screen data. Then, it is just a matter of saving the relevant part as a text file.
I don't know if you can do the same thing within Shell using KingCon type logging, but, as an alternative, I have always used the facility of UBoot Prefs to save the settings to a safe storage location.

That's true for print/set/saveenv but if you can't boot at all due to incorrect uboot settings or want to explore the other commands it has to offer with 'help', unless you're using a serial terminal with a scrollback buffer it wouldn't be possible to read most of the text without stopping it somehow.
Another trick which helps pressing the arrow down at the right time is to turn off the CPU cache as that slows down the 'help' and 'pr' text output a lot.
