Ok, I found another command:

watch -n 0.2 gpio readall  which results in (maybe a bit hard to read):

There I saw some GPIO's with value 0 and some with value 1.
I tried again the GPIO's with value 1 with command - gpio wfi 22 falling -
with succes!
This turned out to be GPIO 6 (instead of GPIO 22 as the previous command
stated.

So now GPIO 6 works!

Problem is solved but I still don't understand why some GPIO's (like 12,
13, 16, 17, 18, 19, 20, 21, 22, 23, 26 and 27)  can't be used since their
value is default 0.

Many thanks!
