What would be the best way to see if a u-boot variable is defined with a script? In other words, I want to check to see if an env variable, say 'testvar' is defined from u-boot script (not from the interactive command line.) I tried to use itest and printenv, but doesn't seem to work.

Any suggestions?

If the hush shell is configured you could use something like that:

if printenv testvar then echo "testvar is set" else echo "testvar is not defined" fi
