I met a comprehension problem after reading third party glitch. Indeed, I talk about Hardware Setup section.
What I don’t well understand at first, it’s the purpose of the 7th step (" 1. Add a header pin/wire to RST (First column from the left, third row from the bottom). The CW-Lite needs two connection points, as we’ll be both resetting this pin and triggering off of it.")
because in the wiki glitch tutorial, Pin-16 of the CW-Lite is used for trigger input and because the “trigger_high()” function set the GPIO at high level to trigger it.
So, why the pin-16 of the CW-Lite is connected to the NRST ? Is it specific to the bootloader attack application ?
Then, my other question is about the 6th point of this same topic. I compare the hardware setup with the R3 (12-ohm resistor) between STM32F3 target board provided by New AE Technology and the target board of the tutorial. In the tutorial, it’s explained to “Add a 12-ohm resistor on the 3.3V_CORE jumper” but when the SMA connector is connected to VCC, the glitch output will be automatically connected to the R3 resistor.
And so, by comparing with the following schematic, we don’t have “SHUNTL” after R3 resistor and “SHUNTH” before R3 resistor ?
