I'd like to use the ENTER key to stop autoboot through the variables
"bootdelaykey" and "bootstopkey". How could I do this?
The problem is to type escape characters ('\r') on the prompt line. I
tried with several possibilities, but nothing worked.
Any suggestions?

Try simply doint what you intent to do:
=> setenv bootdelaykey '
'
That should do the trick.
Note that itis a bit tricky to check this with printenv. You will see
this:
...
=> printenv bootdelaykey
bootdelaykey=
=>
or:
=> printenv
...
bootdelaykey=\
...

I tried, but when I press ENTER key after the first ', U-Boot shows me
a new prompt and delete the variable.

This isn't a problem for me.

Which exact U-Boot version is this?
Are you using the hush shell, or the legacy command interpreter?

I think the legacy command interpreter... how could I check this?

Argh... Please update and use recent code.

Try:
echo a || echo b
Hush will echo only "a", the old legacy interpreter will print
"a || echo b".

Dealing with failure is easy: work hard to improve. Success is also
easy to handle: you've solved the wrong problem. Work hard to
improve.
