Hi, I’d like to take the next step in understanding how to connect the chipwhisperer to another board. I have the level 2 kit.
So, I bought a random board that operates on 3.3 volts. It’s been programmed with the arduino client.
All I want to achieve is performing the captures and analysis of the power signals using the chipwhisperer. I don’t want to use the chipwhisperer to program the board etc.
Initially, I thought I could just use the Advanced Breakout Board (CW506) in the following way:
- Connect chip whisperer 20-pin adapter to 20-in adapter on LEFT side of Advanced Breakout Board
- Connect the small 6 pin grouping labelled “AVR/SPI” on right side of Advanced Breakout Board to the correct pins on the target (MISO to MOSI, etc, etc, etc)
- I’m also assuming here that the Chipwhisperer powers the target through the “AVR/SPI” pin labelled VCCIO (?)
Then hit capture in the Chipwhisperer software. But I haven’t attempted this because I noticed that in the tutorials the chipwhisperer doesn’t seem to measure anything through the 20-pin adapter and uses a seperate measuring line. There is no “measure in” / “measure out” on the Advanced Breakout Board, so I don’t know what to do. Do I splice the VCCIO pin? do I do something else entirely?
Here is the exact pin-out I’m working with:
Would anyone be so kind as to take a few minutes out to tell me (in absolute laymens terms) how to wire everything up (e.g. connect whipwhisperer header to Advanced Breakout Board; connect AVR/SPI pin #1 on advanced target board to pin xx on the adafruit board)? If it’s easier to use the UFO board then I do have that also, but that seems more difficult? I don’t know.
I know this sounds a lot like asking someone to do it for me, and I suppose I am in a way, but I’ve been banging my head against a wall for some time and I think (hope?) that if I can see one real world example with a truly external target that I have access to, perhaps then I can get a feel for why things are done the way that they are, and have something I can apply conceptually myself to other projects.
Thanks in advance to whoever pities this message enough to help out an absolute noob trying to learn about SCA.
