I tried the tutorial : https://github.com/newaetech/chipwhisperer-jupyter/blob/dd4b42baa33f901052b96a626525c64f4e88b66c/Fault_2-Introduction_to_Vcc_Glitch_Attacks.ipynb
with the STM32F0 board.
I spent 4 days playing with the parameters :
width_range = Range(28, 30, 0.4) offset_range = Range(-25, -18, 0.4) ext_range = range(1000, 1005) repeat = 1 # tried with 5 - 10
I am not able to have any good glitch. Only the glitch pin of my chipwhisperer is connected on the target board. I was wondering if someone was successful with this board ? Do you have any strategy to figure out the width / offset / ext_range ?
Sometimes the jupyter script stops without any feedback, the progress bar is red and I can’t figure out what is the problem.
Also when I am trying to brute-force large range of Width / offset/ ext_range , I am not able to retrieve the complete “glitches” arrays. The data seems partial… ( only the last ext_range - 1004 - is included in the array ).
Thank you for your help.
