[U-Boot] Store ENTER ('\r') character in bootstopkey variable
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?

A patched 1.2.0.

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".
