I just purchased an A20 Lime and I getting started with it, the first issue that I cannot solve is an Oops thrown when I try to check the interrupt table.
I am using debian release 2 image wrote on an 8 GB class 10 microSD.
The behaviour I am talking about can be seen below. Have you seen something similar or could you point me any information which might allow me to see the interrupt table.
