user input at u-boot for choosing uInitrd

[g00d]

Hello everybody,

 

is it possible in u-boot (boot.ini) to make a user input and let the user choose from A or B and according to the choice load a particular uInitrd? In case a non-valid answer is given a default answer should be used. Best of all would be if I could implement a time-out. When user does not make input answer B should be selected.

 

I would know how to do this in bash but is that also possible in boot.ini somehow?
