I am trying to glitch the lpc1343, I followed the tutorials:
My glitches are not going to 0V, the minus voltage that I get is 1.05V. Here is the form of the glitch:
But if I compare with a glitch that I did with the UFO board and STM32F3, I can go down 0.5V :
Do you know why without the UFO board, my glitch don’t go under 1.05 V ? Maybe I am doing something wrong with the ground ?
I am using directly the pin 3 (+3.3V) as a voltage source, the pin 2 as a Ground ( from the 20-pin chip whisperer connector )
I am also using the jp11 glitch 3-pins using jumper wires (one on the ground and one on the glitch pin). My jp11 pin is connected directly to the VCC line ( from pin 3 of the CW ).
Thank you for your help.
