[Mehmet]

Hello,
I have a problem in the capture setup section. Although I tried every combination of the code “target = cw.target(scope, cw.targets.CW305, fpga_id=‘100t’, force=False)” (35t,100t,False,True), I receive the same error.

What numbers do the 7-segment displays show on the CW305? Normally it should be 1.00 or very close to it. It may be getting insufficient power from USB. Try a different USB port, or use the DC jack.

If this still doesn’t work, which (if any) LEDs do you see on the board? There should be a red flashing LED just above the FPGA JTAG connector (near the letter “L” on the large Atmel chip).

Hello @jpthibault ,
As you can see in the new picture attached, I use a DC jack for the power, I see 1.00 on the 7-segment display, and 3 LEDs are ON, but none of them are flashing. It must be because of the error I get. In the last trial, I got a different error message. I leave a message here. I am open to every thought. Thank you.

Hello,
I have a “” UndefinedError: ‘bundle’ is undefined “” error. As far as I’m concerned, I am the first person who has this error in this forum. Therefore, I attached a ss and the error code here. Please let me know in this regard. Thanks!

UndefinedError: ‘bundle’ is undefined

Hi,

My best guess for this is that there’s some sort of version mismatch between some of your packages.

Try running the following from jupyter/ChipWhisperer Updating.ipynb:

%%bash
python -m pip pip install -r requirements.txt --upgrade

Then restart and rerun your notebook.

EDIT: Instead of the above, close jupyter and navigate to the chipwhisperer/jupyter in a terminal, then run the Python command. Some packages are in use with Jupyter open, so not everything will be updated if it’s running.

Hi Alex,
Thank you for the suggestion. I tried it and nothing changed(please see the picture and the output). Do you think it is because I didn’t use Xilinx Vivado during the implementation? I wanted to observe the demo, so I just connected CW-Pro and CW-305 to my PC and ran the code without Vivado. Even though I didn’t use Xilinx Vivado so far, I am able to run the attack and get the keys successfully. The only problem is that I get the error while plotting the captured traces. Do you think that I should change some commands for plotting? Thanks.

Hi,

You first need to close Jupyter. Do can do this by going to localhost:8888 in your browser and hitting the quit button at the top right of the page.

Next, run ChipWhisperer Bash, which is installed alongside ChipWhisperer. Finally, run the following command:

cd /home/portable/chipwhisperer/jupyter
python -m pip pip install -r requirements.txt --upgrade

Hi Alex,
It worked, thanks!
