[En-Nut-Discussion] Demo apps: Yellow LED does go off two seconds after program start, can't establish network link

[Georg Kühn]

Hi Harald,

I used a cheap AC power plug.
Other power supplies (regulated ones) don't work either.

What is the normal behaviour of this yellow LED after start of a demo 
application?
Does it immediately switch on and keep glowing all the time?
