I have read the VCC glitching tutorial and have some questions that might sound very stupid.
My understanding from the VCC glitching tutorial was that the glitch should be generated synchronously with the target clock. In the Raspberry PIe example CLKGEN is set to 120 MHZ. I expected that the CLKGEN should be set to the frequency of the Raspberry Pie core. Could you please tell me where 120MHZ is coming from?
Shouldn’t we use the Raspberry’s clock as an input to the Chipwhisperer to be synchronous or clock the raspberry Pie from the Chipwhisperer?
If I want to provide the clock to the Raspberry pie from Chipwhisperer, should the CLKGEN frequency be the same as the XTAL on the board? Should I connect Target HS IO Out in place of the XTAL on the board?
