Hey there,
I’m very new to the chipwhisperer so most of this problem may very well be me being unable to use it correctly.
I tried the first glitching tutorial (A2 introduction to glitch attacks), but the glitching itself via the “manual trigger” button seemed to be not doing anything. I connected an external oscilloscope that showed a nice clock signal but without any glitches when pressing the button (please mind that I’m very new to hardware attacks so wrong usage of the oscilloscope may also be an issue). I used the values from the tutorial.
When I changed the “glitch trigger” from “Manual” to “Continous” the oscilloscope showed continous glitches in the clock signal, so the hardware setup seems to be working.
When manipulating the glitch width and offset and toggling the glitch trigger from manual to continous and back to manual at the right moment the loop yielded the expected wrong results.
Is it me being seemingly unable to follow a tutorial or is there a real issue with the chipwhisperer software or fpga firmware ?
Thanks in advance,
cyberdemon
