Hardware version here is 1.2
I’ve made the suggested modifications (removed the line resetting successes to 0, and indenting up the attack1_data line) and ran with the following parameters:
offset_range = Range(-49, -30, 0.2)
scope.glitch.ext_offset = 37
scope.glitch.repeat = 10
width_range = Range(-10, 10, 1)
And I indeed got a good bunch of successes, at many different offset/width values actually. Not sure I fully understand the turnaround on this one, but it does finally work. Thanks!
I am still very confused by the increments being different than 0.2 and 1 respectively (?). 1 seems mapped to 6/512 while 0.2 seems mapped to 2/512… Some kind of rounding up to the next step value?
Now trying to figure out the issue with the VCC Glitch tutorial.
By the way, using the same ranges/steps for offset/width in the Attack 2 of the Clk Glitch tutorial, I am getting a ton of “WARNING:root:Timeout in OpenADC capture(), trigger FORCED”, and a few “Timeout happened during acquisition”. Not sure why. But I did get successes as well.
